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.
