“Here at Mimaki, we do not stop at developing disruptive technologies – we make it our business to look even further beyond this, continually striving to find ways in which we can then accelerate the adoption of these technologies and drive the wider industry forward,” comments Danna Drion, Senior Marketing Manager at Mimaki Europe. “Our new 3DUJ-2207 3D Printer is a prime example of this. We had already raised the bar in 3D printing by delivering the world’s first 3D printer with over 10 million colours – but now, with the introduction of our new 3DUJ-2207 3D Printer, we are bringing these 10 million colours to a host of new customers, which in turn means new applications and an even quicker uptake of 3D printing technologies as a whole.”

Set to be commercially available worldwide from January 2021, the 3DUJ-2207 has been designed with functionality at its core, with the compact design and reduced 203 x 203 x 76mm build space just two of many key features which demonstrate its unique versatility and make it ideally suited for office environments. The 3D printer’s quiet performance and optional deodoriser minimise some of the primary disruptions usually associated with 3D printing technologies, ensuring maximum workability in busy workspaces.

Utilising UV-curing inkjet technology, the expansive high-definition colour expression made possible with the Mimaki 3DUJ-2207 3D Printer is around twice that of powder bed manufacturing methods. This provides new possibilities for prototyping and enables the accurate reproduction of subtle colour differences which are critical for many industrial design applications such as medical and architectural modelling. Additional applications include small-scale models for design offices and educational settings, as well as collectible figures.

Drion concludes, “By combining our technological expertise with a wealth of industry experience and market insight, we have been able to create an innovative, inspired solution that merges functionality, affordability and design in a way that really will be game-changing for a lot of creators. This launch will deliver a world of new possibilities to designers and product developers, for many of whom the idea of high-definition full-colour 3D printing might previously have been out of reach, and that is something we are extremely proud of.”

Envisiontec Speed and Castability: What Factors Affect Final Casting Results?

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.

IT’S SUPER-FAST — CONTINUOUS DIGITAL LIGHT MANUFACTURING

  • 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.

Application Note: Chemistry Advancements for Automated Resin Removal: PLM-403-SUB

CONTENTS

I. Summary
II. Testing & Validation of SLA Resin Removal Solution
III. Conclusion

I. SUMMARY
This paper examines PostProcess Technologies’ newly released resin removal chemistry, PLM-403-SUB (referred to as 403 from here on), as part of its comprehensive Automated Resin Removal Solution. It will review the effectiveness across a range of materials, safe operations, and process optimizations as compared to traditional alternatives isopropyl alcohol (IPA) and tripropylene glycol monomethyl ether (TPM).

The goal of the new 403 chemistry is to, in concert with the software and hardware components of the resin removal solution, ease the multiple burdens that typically arise when removing uncured resin following various Vat Photopolymerization processes. With this solution, users can dramatically reduce cycle times, process steps, and the typical operational risk factors that come with legacy resin removing solvents.

II. TESTING & VALIDATION
The PostProcess 403 chemistry is a new formulation that improves upon the performance of the previously released PLM-402 SUB (referred to as 402 from here on). The primary benefits of the solution are the same as those identified previously with the 402 detergent, including industry-leading cycle times and reduction of required process steps. Unlike previous methods which may have required both TPM and dirty IPA baths followed by various rinse steps, cycle times with 403 in PostProcess’s patented hardware technology are frequently less than 10 minutes. Additionally, the process takes place within just one piece of equipment. This effectively cuts down on both attended and unattended process time. The user can simply load and unload from the system, and perform a quick rinse before moving to the post-cure step. This is compared to cycle times of 20+ minutes in multiple TPM/IPA baths which involve operator intervention throughout the cycle to move from one step to the next.

The 403 chemistry has been successfully used to remove uncured resin from the model materials listed in Table 1 (as of publication date noted in the footer). Ongoing validation tests for additional resins are being conducted with the intention of covering the vast majority of resins available, and will be updated periodically in this document available on the
PostProcess website.

One of the most important factors for users, after ability to clean parts, is the detergent life, or longevity. This typically determines the frequency of labor-intensive equipment cleaning efforts. Longevity for resin removal detergent is typically defined as the amount by weight that the chemical solution can hold and still effectively remove resin. As most users look to remove resin as quickly as possible, the longevity of various solvents are compared while holding 10 minute cycle times. From the data depicted in Figure 1 and in Table 2, 403 has significantly better longevity (capacity by weight of resin in solution at 10 minutes) than all other typical solvents (i.e., IPA, DPM, TPM) used to remove uncured resin from printed parts. Likewise, 403 has 6% improved longevity versus PostProcess’s previously released industry- leading chemistry, 402.

Figure 1: Saturation of various chemical solvents for resin removal

The saturation of the 403 chemistry with removed resin can be measured using the hydrometer (see Figure 2 and Table 3 below), which is provided with every PostProcess Automated Resin Removal Solution.

WASTE CONSIDERATIONS
Due to its increased longevity, 403 offers a significant reduction in waste generation compared to other solvents. Subsequently, the lower frequency of chemistry changeouts reduces the required maintenance labor hours in the process.

The detergents used in the resin removal process will also contain the uncured resins in solution. These resins do not become less hazardous after removal, and are all considered hazardous materials in the chemicals used to remove them. The frequency and volume of waste disposal will be a factor in the total cost to dispose of the exhausted chemicals.

MECHANICAL PROPERTIES OF SLA PARTS AFTER RESIN REMOVAL
An initial set of tensile testing has been conducted to show mechanical property integrity compared to existing solvent cleaning methods. Accura ClearVue, Accura 60, and Accura Extreme Grey were all subjected to a resin removal process using 403 and IPA, along with a control group in which the uncured resin was carefully wiped off. Following these procedures, all tensile bars underwent a curing step according to manufacturer recommendations. Key properties have been compared below.

As shown above, tensile strength at yield is within 5% of the control group for both 403 and IPA processed parts. Values for tensile at break are also nearly identical for 403 and IPA. While elongation varies slightly, it still lies within the manufacturer specifications (3-15% for ClearVue, 5-13% for 60, and 14-22% for Extreme Grey) for both 403 and IPA. In summary, when moving from an IPA cleaning process to the PostProcess solution utilizing the 403 chemistry, mechanical properties will not be significantly affected.

SAFETY CONSIDERATIONS
Inhalation and combustion risks during the resin removal process are a widespread concern for all resin removal users. Additionally, regulations can significantly limit the amount of combustible resin removal liquids that can be stored on site in a facility. The 403 chemistry has improved safety and environmental characteristics that address these issues, as seen in Table 5 below.

The high flash point of 403 (220°F, 104.4°C) means far less vapor will end up in the air near the machine, especially when compared to a volatile solvent like IPA. With typical process temperatures ranging from ambient temperatures (75 – 85°F, 23.9 – 29.4°C) up to 120 – 130°F (48.9 – 54.4°C) for the PostProcess Resin Removal Solution, there is still a very large gap before reaching the ¼ LEL temperature of 163°F (72.8°C).

STORAGE
For higher volume resin removal, where large volumes of chemical are required to remove the resin, 403 addresses storage limitation issues with flammable liquids.

The amount of flammable/combustible resin removal liquids that can be kept on-site is limited by various regulations. Liquids with a flashpoint below 200°F (93.3°C) are usually limited to 120 gallons (454 L). Conversely, liquids with a flashpoint greater than 200°F (93.3°C) can usually be stored in quantities up to 13,200 gallons (5000 dekaliters). Because 403 has a flashpoint of 220°F (104.4°C), it can operate and be stored in much larger quantities than other resin removal chemistries, as summarized in Table 6. Table 6 is specific to the United States. Please refer to your local regulations when outside of the US.

ENVIRONMENTAL & SUSTAINABILITY
The new 403 chemistry is an environmentally-friendly alternative. It has a much lower vapor pressure than other solvents, and a 220°F (104.4°C) flashpoint that makes it much safer to use. In 402, D-limonene was used to help with resin removal. Although generally safe to use, it has been replaced in 403 with a more environmentally-friendly option that reduces risks following the waste removal step.

Once saturated with resin, 403 can be recovered for reuse by distillation. Under a typical vacuum distillation, up to 90%+ of 403 by saturation weight (amount of resin in solution) can be recovered for reuse of the detergent. This makes 403 a particularly sustainable option.

With reduced waste generation, lower vapor pressure, and higher flashpoint than any other option on the market, the 403 chemistry is the most sustainability-friendly solution available.

III. CONCLUSION
PostProcess Technologies’ new 403 chemistry as a part of its comprehensive Automated Resin Removal Solution is a definitive improvement over current mechanical and chemical technologies used to remove resin in Vat Photopolymerization 3D post printing. Through a combination of breakthrough chemistry, patented hardware technology, and proprietary software, uncured resin removal can be accomplished in 10 minutes or less for simultaneous trays of printed parts. This newest formulation offers a much higher resin capacity, yielding a longer useful life compared to other chemical methods. With intuitive software controls and process monitoring, the speed and ease of use of the solution results in increased consistency at levels required for production volumes. Ultimately, the attended operator time is greatly reduced and the 403 chemistry is inherently safer to use and store.

New collaboration to accelerate adoption of industrial metal AM

Desktop Metal has announced a new collaboration with Cetim, the France-based Technical Centre for Mechanical Industry. The partners will work together to promote and accelerate the global adoption of metal additive manufacturing across industrial sectors by identifying market opportunities for AM and supporting innovation across Cetim’s customer network. As part of the partnership, Cetim has already become, in last August, one of the first adopters of Desktop Metal’s new Shop System metal binder jetting platform.

Cetim was inspired to work with Desktop Metal after successfully installing and utilizing the Studio System at its facility in Cluses, France. The center will continue to leverage this system for rapid prototyping and low-volume production while has also added the Desktop Metal Shop System’s capability for low-volume prototyping or mid-volume runs of complex metal components. These resources will enable Cetim customers from across the aerospace, oil and gas and automotive sectors, to name a few, to explore new AM applications and opportunities.

“As the demand for metal AM continues to grow, it is challenging for many of the mechanical industry companies we work with to identify the right solution that meets their needs and then to implement it in an effective and cost efficient way,” explained Pierre Chalandon, COO at Cetim. “Desktop Metal technologies with both the Studio System and new Shop System completes our additive manufacturing machines park. From a general point of view, Metal Binder Jetting Technology is promising for a large part of our clients. Desktop Metal solutions portfolio covers the full metal product lifecycle, which is complementary to our experience on sintered material and finishing operations.”

The fine detail of a part 3D printed using the Shop System

The Desktop Metal Shop System, unveiled at Formnext 2019, is a metal binder jetting technology designed specifically for machine shop use and is capable of producing complex metal components with both speed and quality. The solution is also notable for its relative affordability: the Shop System starts at $150,000. Desktop Metal says the system is designed to enable shop manufacturers to “tap into new opportunities to reduce their costs and increase revenue.”

Through the partnership, Desktop Metal and Cetim will also work on a range of research projects involving Desktop Metal’s metal AM technologies, including design for metal AM processes, post-processing and finishing technique qualification, workflow optimization and materials development. Cetim brings to the table its extensive knowledge of metal AM processes (including LPBF, WAAM, MBJ), which it has built up over the past 15 years. In recent years, Cetim has been particularly involved in the development of metal binder jetting, which it believes creates new opportunities for production capacity and material range. The French center is also actively involved in the normalization of metal AM, coordinating the Additive Factory Hub (AFH) with the aim of implementing AM to address industrial and economic challenges.

“When it comes to empowering industrial companies with the additive manufacturing technologies of the future, Cetim is truly one of the leaders in Europe,” concluded Ric Fulop, CEO and Co-Founder of Desktop Metal. “We are excited to partner with Cetim as one of the first customers for our ground-breaking Shop System and are eager to collaborate with Cetim on our shared efforts to change the way that companies manufacture around the globe.”
