Desktop Metal Expands Its Metal 3D Printing Materials Library With Global Launch Of Pure Copper For The Studio System

Now Commercially Available to Studio System Customers Worldwide, Copper Enables High-Performance, Highly Optimized Parts for Oil & Gas, Auto and Consumer Products Industries

December 7, 2020 BURLINGTON, MA – ​Desktop Metal​, a leader in mass production and turnkey additive manufacturing solutions, today announced the launch of copper for the Studio SystemTM, an office-friendly metal 3D printing system for low volume production. With its excellent thermal and electrical conductivity, copper is considered an ideal material for transferring heat or electricity and is used in virtually every electronic device made, as well as in many of the heat exchangers used across a variety of industries, including oil and gas, automotive, and consumer products.

A key benefit for Desktop Metal customers is that the copper material used with the Studio System is pure copper. Unlike laser-based processes, which often print chromium zirconium copper, the Studio System’s proprietary Bound Metal DepositionTM process is able to print pure copper, unlocking the full benefits of the material.

“Known for its excellent thermal and electrical conductivity, copper is a highly desired material for a variety of industries and applications, such as heat exchangers and electrical components for heavy industries to consumer products,” said Jonah Myerberg, CTO and co-founder of Desktop Metal. “Whether for heat sinks, electrical motor and power grid components, or resistance welding electrodes, 3D printed copper on the Studio System is an ideal choice for manufacturing parts featuring complex geometries.”

Early customer applications demonstrating the material’s benefits include:

Manufacturing: Electrode Holder

Electrode holders are used to hold electrodes in position during resistive nut welding. Printed in copper, the part features internal conformal cooling channels to improve temperature regulation. Electrodes are consumable and need to be replaced quickly and affordably when they wear out to keep the manufacturing line up and running. Using copper in combination with conformal cooling channels helps to pull heat off the electrode and the electrode holder to better regulate the temperature, leading to a better weld and a longer part lifetime.

Automotive: Motor Heat Sink

Heat exchangers are designed to help dissipate heat from an electric motor while the motor operates, keeping the motor at a more ideal operating temperature. The Studio System allows for the copper heat exchanger to conform to the motor shape, distributing heat more efficiently from the motor to the surrounding environment. The tall, thin fins in this motor heat sink are easily customized using 3D printing on the Studio System, whereas they are more challenging to manufacture via machining, due to chattering as the fins are cut.

Chemical Processing: Helical Heat Exchanger

Helical heat exchangers are used to cool a hot gas as it flows through a pipe. The Studio System allows for the heat exchanger to be printed with an internal helical channel that enables cooling fluid to flow through it. The complex geometry of that channel can only be made with additive manufacturing.

Electric Power Distribution: Bus Bar

Bus bars are used for local high current power distribution. As power is being transferred, the bus bar begins to get hot, internal cooling channels help to regulate the temperature, and copper’s excellent thermal conductivity value ensures that heat is efficiently transferred from the bus bar to the coolant. The bus bar’s design features complex cooling channels running through its core. Using the Studio System, the bus bar can easily be printed as a single copper part complete with internal cooling features. Using traditional methods, the channels would require a multi-part assembly to create the final part.

Copper is the latest addition to the Studio System materials library that also includes 4140 chromoly steel, H13 tool steel, 316L, and 17-4 PH stainless steels. In addition to materials that are already available, Desktop Metal’s team of materials scientists are continuously working to develop new materials and processes to make 3D printing accessible to even broader industries and applications.

Studio System for Producing Complex Parts In-house

The metallurgy behind the Studio System is built upon the materials science and established powder supply chain of the metal injection molding (MIM) industry. When combined with Desktop Metal’s in-house expertise in material processing, binder compounds, and metal 3D printing, the results are high-quality metal parts with affordable material costs.

Key Studio System benefits include:

  • High-quality parts. Users can easily 3D print difficult-to-machine parts with up to 98 percent density and featuring complex geometry-like undercuts and internal channels. Fabricate® software automates complicated metallurgical processes to produce high-quality parts with densities and feature accuracy similar to casting.
  • Easy to use. The Studio System is built to make 3D printing metal parts as easy as uploading a design to Fabricate software and pressing print with no guesswork or manual calculations required. Material changeovers are quick and easy, enabled by a unique, hot-swappable material cartridge design.

  • Designed for the office. The Studio System is designed to seamlessly integrate 3D printing into design and engineering workflows. By eliminating lasers and loose metal powders, the system easily assimilates into a team’s work environment with no third-party equipment and minimal facilities investment required.

Leveraging DfAM for Enhanced FDM Post-Printing Efficiencies with PostProcess Technologies


I. Introduction to Design for Additive Manufacturing

II. FDM Background

III. DfAM Strategies

IV. Results

V. Conclusions


Additive manufacturing (AM) is a powerful technology that lends itself to producing organic geometries, and building parts in short timeframes. Additive technologies are capable of printing shapes that cannot be created by any other means. One of the most salient factors in successfully building these unique designs is the utilization of soluble support material.

As is well-known by anyone who has worked with additive technology, 3D-printed end use parts and prototypes do not come off of the printer “customer-ready.” Virtually every printed part, regardless of print technology, requires some sort of post-printing, whether that be support removal, resin removal, surface finish, or all the above.

As the additive production process has been classically categorized into three separate silos; design, build/print, and post-print, the final step is all too often an afterthought. Rather than considering the additive process a linear, sequential one, PostProcess Technologies embraces the ideology that efficiencies and end part results can be dramatically improved when all of the steps are conceptualized as interdependent.This integrated approach is an advanced ideology that will be necessary to scale additive’s impact, and eventually usher in Industry 4.0.

This paper will identify the ways in which designing for additive manufacturing (DfAM) can affect efficiencies, cost, and support material usage in Fused Deposition Modeling (FDM) printing. Print orientation, support settings within the slicing software, and part design are all aspects which can be leveraged to streamline additive workflows, and facilitate faster, more cost-effective post-printing.

It should be noted that while some of these DfAM for FDM techniques can be applied to other print technologies, this is not the case universally (e.g. self-supporting angles are also useful in DfAM for stereolithography (SLA), but not selective laser sintering (SLS) or PolyJet).

As a rule of thumb, DfAM will have a greater effect in circumstances where there is a higher level of design freedom. While DfAM will have a minimal impact on rapid prototyping or tooling applications (situations with the lowest allowance for design freedom) manufacturing aides and end-use production parts allow for more unique designs, thus making DfAM more significant. The more design principles that are considered upfront, the less time must be later allotted to redesign, or the removal of unnecessary support structures later in the process.



To comprehend the DfAM techniques that will streamline an FDM workflow, it is vital to comprehend the advantages and limitations of the print technology, and why it is one of the most popular 3D printing technologies available today. The process starts with a thermoplastic filament wound in spools. This filament could be ABS, Polycarbonate, or Ultem™*, for example (see the image below for a complete list of Stratasys thermoplastic materials available for use with the brand’s FDM printers). Strength requirements, the temperature that the part will be exposed to, its performance expectations, and the sort of chemical resistance that it requires are all factors that may impact material selection.

The filament is extruded through a heater block, then a nozzle, and computer-controlled motion is used to deposit the melted thermoplastic. As the deposited plastic cools, the z-stage build platform is lowered to create the 3D part. While this layer-by-layer deposition process is ideal for parts with low heights, FDM printers can face challenges printing complex geometries with tall and thin walls. Virtually anywhere there is an overhang on an FDM part, support material will likely be required to prevent build failure, leading to high support material usage. Consequently, FDM processes involve tedious support removal steps, which traditionally involve dissolving support material by using detergents or breaking the supports away manually, depending on the support material used.

As reported by the PostProcess Technologies’ 2020 Annual Additive Post-Printing Trends Report, material extrusion printing methods (e.g. FFF, FDM, MEM) are utilized by 71% of additive manufacturing users, making them the most popular print technology. The top challenge of material extrusion technology was found to be the length of time to finish parts, while the runner-up answer was damaged parts, both issues that DfAM can help mitigate. That being said, additional research has found that 23% of the average part cost for polymer 3D printing is attributed to the post-printing step alone (Source: 2019 Wohler’s Report). Finally, keeping support material to a minimum is ideal in lowering the build time required for a part, the material cost of a part, as well as the time and resources which must be allocated to the post-printing step.


Depending on the geometry of your part, orientation may play a paramount role in DfAM. Usually a sole aspect like part strength, support structures, print speed, or surface quality must be prioritized to determine the best orientation of the part. Strength is most often the driving factor for orientations, though priorities may change depending on print materials used, or time restraints. Considerations regarding part orientation should be explored during the design phase to proactively ensure minimal support material requirements, as well as printing and post-printing speeds.

Figure 1 shows a L-bracket printed on its end and Figure 2 shows the same L-bracket printed flat on its side. Utilizing GrabCAD Print software, the green represents the model material of the part and the orange represents the support material required to print the part in that orientation. This change in build orientation accounted for a 58% reduction in build time, and a 91% reduction in support material usage, equating to cost, material, and time savings.

Part Design
Knowing the advantages (and limitations) of a print technology is vital in designing the most efficient, structurally-sound part possible.

Self-Supporting Angles

FDM is one of the only technologies that leverages self-supporting angles. Typically, as long as there is at least a 45° overhang to the build platform, support materials will not be needed. This strategy can also come into play by implementing chamfers and/or fillets, for example see Figures 3 and 4. Also by using the SMART support settings within GrabCAD Print or Insight on Stratasys printers, the software will automatically utilize self-supporting angles when developing support structures, which will help to reduce the amount of support material needed in comparison to other support styles. The actual self supporting angle value will vary based on the printed model material and the slice height that the printer is set at. For example, on a Stratasys Fortus 450mc, loaded with ASA material and printing at a slice height of 0.010” / 0.254 mm will have a self-supporting angle of 43°, whereas Nylon 12CF is 50°.

FIGURE 3: Overhanging Geometry Example
FIGURE 4: Self Supporting Geometry Example

Implementing Strategic Holes
Designing vertical, non-critical holes as diamond or teardrop-shaped instead of round will reduce the amount of support material required (see bearing block image below). Critical diameter holes should be printed in the XY plane if possible. If the vertical holes require tighter accuracy, they may be drilled out in a post-printing step. When using an automated support removal system it is best practice to reduce the amount of blind holes and cavities. Rather, when possible implement through holes and open cavities, allowing the support removal detergent to flow through those areas more freely, and remove support material faster.

Material Usage
In certain circumstances, utilizing model material as support material can decrease build time, specifically by reducing wait time caused by the printer switching between model and support material. However, this time reduction is only realized if the entire layer’s support material can be changed to model. Whenever you slice a part in GrabCAD Print or generate support material in Insight, the software automatically generates support material and will interface directly with the model material, giving it a good foundation to build model material on. When changing the support material to model material, you will want to leave the three or four support material interface layers, or the layers below where the model material starts, as support material. Otherwise, the model support may end up fused to the finished part,
subsequently causing damage to your overall part.

Surface Finishing
Orientation can also impact the surface finish of a part. Exterior contour toolpaths will result in a better surface finish than exposed raster toolpaths, as rasters are more likely to cause air gaps, which can prove difficult to remove. While flat orientations may print faster, particularly with FDM, horizontal orientations with exterior contour paths will take significantly less time to post-print (see example in image below). FDM parts will also always have a “seam”, which is the start/stop point of each build layer. Utilizing the slicing software to determine where a seam should be placed can help reduce surface finishing time on specific part areas.


As a result of implementing the various DfAM techniques that this white paper covers, small-scale FDM parts were able to achieve significant build time and material savings, thus streamlining the entire additive process. Below is a step-by-step explanation of what part features were changed in the CAD modeling software, and what settings were changed in GrabCAD Print to achieve the desired results, reducing build time and support material usage.

Sensor Bracket Part

Part features added:
– Interior and exterior fillets added to increase the strength of the bracket.

GrabCAD Print Settings:
– Orientate the part with the “L” profile in the XY plane of the build platform (see picture below).
Reduce the amount of support material required by selecting “Do not grow supports” in the Support Settings.

Bearing Block Part

Part features added:
– Modified the mounting holes from round to diamond shaped, making the geometry self-supporting.

GrabCAD Print Settings:
-Orientate the part with the diameter of the large vertical hole in the XY plane of the build platform (see picture below).
– To place the layer seams on the back of the part (a noncritical surface) select the surfaces where you don’t want the seam placed (critical surfaces), and select “Avoid Seams” in the Model Setting section. This will help to reduce surface finishing time on critical surfaces. This feature only works for parasolid part files that are imported into GrabCAD Print, and will not work with STL files.

Coupling Part

Part features added:
Changed the angle of the coupling from 35° to 45° to make the geometry self-supporting.
Added a fillet between the base of the part and the vertical cylinder to help strengthen that area.
Added a chamber under the top tabs to make the geometry self-supporting.

GrabCAD Print Settings:
Orientate the part with the round base in the XY plane, as shown below.

V. Conclusions

  • To utilize additive to the best of its ability, it is essential to recognize that the design, build, and post-print steps are heavily integrated. It is most strategic to consider support removal and surface finishing during the design phase.
  • When designing an FDM part for optimized post-printing, factoring in material selection, part orientation, self-supporting angles, contour toolpaths, as well as chamfers and fillets as needed, can contribute to time, cost, and materials savings.
  • Automated post-printing solutions from PostProcess Technologies can further enable efficiencies within additive workflows, and cut down on overall time and money spent on the AM process. The proprietary Volumetric Velocity Dispersion technology for soluble support and Suspended Rotational Force for surface finishing both leverage various chemical and mechanical energy sources for optimal post-printing for FDM.

Over the past few years, 3D printing has been transforming the jewelry industry. The introduction of 3D printers gives jewelers the capability to produce castable, high detailed parts in a fraction of time. But not all 3D printers are created equal, and casting results may vary widely, leaving some custom jewelers and manufacturers frustrated.

Additive manufacturing cuts production time dramatically when compared to traditional hand-carving methods and lately there has been a race for developing faster 3D printers for jewelers to produce rings in a matter of minutes and not hours. But does build speed really matter in 3D printing?  Should you have to sacrifice quality to achieve it?

With a long standing history of 3D printing innovation, EnvisionTEC focuses on real solutions to real application problems. The company introduced its patented Continuous Digital Light Manufacturing (cDLM) technology so that jewelry professionals wouldn’t have to choose between speed and quality.

DLP technology, which was first developed and patented by EnvisionTEC, has been the gold standard for 3D printing jewelry.  A standard DLP 3D printer builds parts in layers, one layer at a time. Each layer must be exposed to the light source and the time of exposure is defined by layer thickness and material reactivity. Once a layer has been exposed, and the specified layer is formed, a layer separation procedure is performed to peel the layer from the bottom of the material tray and replenish fresh resin to cure the next layer.

Over the years, EnvisionTEC has perfected a number of patented methods of minimizing the effects of this peeling separation, with highly castable options available to the jewelry industry that are widely used from custom designers to large manufacturers.  But there are limits to the amount of wax that can be used with DLP 3D printing.

When using wax-based materials, the exposure times are typically three to four times that of regular plastic acrylic polymers. The higher the material castability (i.e. wax content), the slower the exposure time. A number of other 3D printer manufacturers claim that they can produce rings in minutes using a standard layer peeling process. However, their resins contain much more plastic than wax, resulting in less than optimal casts with significant surface roughness and porosity.

EnvisionTEC’s cDLM technology works by adding an air gap (similar to the air gap below the puck on an air hockey table surface) between the part being built and the bottom of the material tray.  By building a floating layer, the separation forces are completely eliminated – so there is no peeling at all.  With no separation forces, cDLM 3D printers are able to print resins with up to a 90% wax fill (Easy Cast 2.0), allowing for patterns that are as easy to cast as any traditional hand-carved or injection molded wax pattern.

On top of all of this, the cDLM process is fast, allowing jewelers unprecedented manufacturing turnaround times. Traditionally, 3D printing castable materials would take hours to build. However with the cDLM technology, bridal and fashion rings can be designed, grown, and ready for investment casting the same day, which is a huge advantage for the jewelry market.

If you need a solution for 3D printing premium quality wax patterns for jewelry quickly that can also be easily casted, view EnvisionTEC’s cDLM technology. For more information visit:  EnvisionTEC Castables.


  • Parts built as the platform moves continuously without separation, which leads to a drastic reduction in the building time as well as allowing for highly wax-filled resins to be used.
  • A drastic reduction in separation, forces delivery of highly accurate parts, with detailed feature resolution.
  • Better castability, as the wax based resin is cured twice as much during the build process, when compared to building using non continuous traditional DLP 3D printers. This delivers a porosity-free casting from EnvisionTEC’s ash free castable materials.
  • And more rings printed in Easy Cast 2.0 at 15 µm on the EnvisionTEC Vida UHD cDLM.

Syqe Medical reaps benefits of sustained high temperature parts with XJet Additive Manufacturing

Rehovot, Israel – November 4th, 2020 – XJet Ltd. has revealed today how Syqe Medical, the manufacturer of a revolutionary medical inhaler, is using XJet NanoParticle Jetting™ (NPJ) technology to create parts impossible to produce with other manufacturing methods.

Syqe Medical’s Selective-Dose inhaler aims to increase the effectiveness of patient treatment by delivering a range of drugs in breakthrough precision levels. This new level of precision allows patients to reach the coveted optimum balance between symptom relief and adverse events, and regain their quality of life.

Finding a need to build a high-precision, high-temperature and electrically insulated test facility for product development, Syqe Medical first looked to PEEK materials and traditional manufacturing methods because of the heat resistance requirements. However, according to Syqe Medical Founder and CEO Perry Davidson, design processes were constrained, requiring many adjustments and consequently, production costs were high, delivery times long and yet still the materials were not durable enough.

“Realising we needed another solution, we turned to XJet,” elaborates Itay Kurgan, Product manager at Syqe Medical. “We have a wealth of experience with additive manufacturing technologies and whilst the polymer materials don’t have the heat resistance we needed, XJet ceramic materials are resistant to temperatures even higher than our requirements and of course they are electrically insulated. Minor design adjustments are very easy, and results are precise and repeatable, so we can achieve optimum accuracy and delivery times are very fast. Where all other options were flawed in at least one aspect, XJet provided the perfect solution.”

The XJet Carmel 1400 AM system – featuring the company’s patented NanoParticle Jetting technology – enables the production of ceramic parts with the ease and versatility of inkjet printing. Using ultrafine layers, the Carmel system produces ceramic parts with superfine details, smooth surfaces and high accuracy which are preserved with the use of soluble support material which simply washes away.

“Syqe Medical is making life-changing advancements in the field of patient care so we’re delighted to see them reaping the rewards of XJet’s unique capabilities. Ceramics have some very valuable material properties, but it can be difficult to exploit them due to difficulties in the manufacturing process. XJet delivers all the benefits of ceramic materials, with accuracy and precision, but without the difficulties of traditional manufacturing,” says XJet CBO Dror Danai.

Desktop Metal receives multi-million dollar award to mass produce cobalt-free hardmetal parts

Metal 3D printing company Desktop Metal has been awarded a three-year $2.45 million dollar project from the U.S. Department of Defense (DoD) to develop a high-volume 3D printing process for the mass production of Cobalt-free hardmetals.

Desktop Metal’s proprietary Single Pass Jetting (SPJ) technology will be used to mass manufacture the cobalt-free hardmetal parts, made from a novel, iron-based nano material, at a rate of 200,000 parts from a single machine, per day.

“The novel Co-free hardmetal grade is expected to yield a high strength, high toughness, high hardness, and high wear resistance material,” said Dr. Nicholas Ku, materials engineer at CCDC Army Research Laboratory (ARL). “We believe combining this novel material with Desktop Metal’s Single Pass Jetting technology will have major applications not only in the defense sector but also in the commercial sector.

“Further, we believe this combined method will dramatically improve sustainability, reduce the use of a conflict mineral and provide an environmentally-friendly process to mass produce parts with superior properties.”

Desktop Metal’s SPJ technology 

The Desktop Metal Production System is a large scale machine which utilizes SPJ technology – an inkjet and powder-based method of metal 3D printing. In comparison to conventional binder jetting methods, which use multiple carriages and pass over a build box to print each layer, Desktop Metal’s patent-pending bi-directional SPJ technology consolidates these steps into the motion of a single print carriage. This significantly reduces print time and removes unnecessary steps to increase the Production System’s mechanical efficiency.

In fact, the company claims the Production System can achieve print speeds up to 100 times those of legacy powder bed fusion 3D printing technologies.

Chicago-based advanced digital manufacturing company Fast Radius was one of the first companies to receive Desktop Metal’s Production System in 2019, as it looked to further expand its global metal additive capabilities. Shortly after, Ford Motors also integrated the Production System to accelerate prototyping and manufacture limited scale production parts, after leading a $65 million investment round for the firm.

Most recently, Desktop Metal merged with blank check company Trine Acquisition Corp to go public with its 3D printing business, a move which will see it listed on the NYSE with an estimated equity value of $2.5 billion. Following the announcement, 3D Printing Industry investigated what this transaction could mean for the wider additive manufacturing industry.

Mass manufacturing cobalt-free hardmetals

Cobalt is a naturally occurring element typically used as a metallic binder material for cemented tungsten carbide. While a critical component in items such as lithium-ion rechargeable batteries, Cobalt has also been linked with negative respiratory and dermal side effects, particularly to those who are mining it. The mining of Cobalt also poses environmental issues, such as increased radioactivity levels and polluted rivers and drinking water.

The ARL has therefore been investigating a replacement for Cobalt, culminating in the development of a patented cobalt-free hardmetal material that uses a novel iron-based nano material as its matrix.

Once the material had been developed, the U.S. Army Contracting Command tasked Desktop Metal with providing a cost-effective, high volume process able to print the novel hardmetals, on behalf of U.S. Army Research Laboratory to the National Center for Manufacturing Sciences (NCMS) and the Advanced Manufacturing, Materials and Processes (AMMP) consortium.

During the project, Desktop Metal will develop a feedstock and binder system for the cobalt-free hardmetal. Without the use of tooling, the firm’s SPJ process will print the novel hardmetals into complex, net, or near-net shaped parts. The goal of the project is to print at least 200,000 parts per day from a single machine.

Desktop Metal will also deliver a cost analysis to step up its SPJ technology for the manufacture of at least 500,000 prototype parts. The company believes its SJP process will “lead the development” of a dual-use technology suitable to various commercial and DoD applications.

Desktop Metal’s decision to go public could raise it $575 million in additional funding. Image via Desktop Metal.

The carbide hardmetals sector

According to Desktop Metal, the carbide hardmetals market is projected to grow to $24 billion by 2024. Carbide hardmetals are used in multiple dual use applications spanning sectors including oil and gas, chemical and textile, agricultural tools, aerospace, defense, construction, and more.

Dr. Animesh Bose, vice president of Special Projects at Desktop Metal, will serve as principal investigator of the three-year project. A fellow of ASM International and APMI International, Bose has amassed 40 years’ experience in processing particulate materials.

“The success in this project will not only provide the hardmetal community with their eagerly desired Co-free hardmetal solution, but also result in the development of a tool-free processing technique capable of fabricating this class of materials into extremely complex shaped parts at speeds that can rival most other high-volume manufacturing techniques, opening op new horizons in the area of hardmetals and its applications,” he said.

It’s expected by the relevant parties that this project will aid in providing a more environmentally friendly way to mass produce metals, alloys, and other composite parts for both DoD and commercial applications.
