Why ETEC?

High Accuracy + Feature Detail

High-resolution printing with Industrial DLP Chips

DLP chips come in a variety of configurations, from industrial chips designed for 3D printing to less expensive chips intended for video projectors found in many offices. While some DLP print technologies choose to use these inexpensive chips to reduce costs, ETEC only uses true industrial DLP chips, which allow for higher contrast ratios, resulting in finer part details.

High-resolution printing with CDLM Domeless Printing

https://etec.desktopmetal.com/wp-content/uploads/2022/01/MS_DM_EnvisionTec_E1_CDLM_320.mp4

To print continuously (without peeling) requires flowing oxygen through a permeable film just above the print bed to create a “dead zone”. Within this ‘dead zone’ the polymerization process is inhibited ensuring the layer being printed adheres to the layer above and not the printing bed film. This ‘dead zone’ is what enables continuous printing, where the build plate can continually move in the Z axis, leading to faster, more reliable prints.

On competitor “dead zone” printers, by comparison, air pressure from the flowing oxygen causes the film to dome up. Printing parts on that domed surface greatly impacts resolution along the Z axis, as well as the ability to print flat parts on the build plate.

ETEC’s CLDM technology uses over 200,000 pillars to hold the film perfectly flat, resulting in significantly better Z-axis resolution and allowing for the printing of flat parts straight to the bed with no supports.

Smooth Surface Finish

Smooth surface finish with Pixel Shifting

Projectors deliver light in square-shaped pixels, which creates volumetric pixels, or voxels, as resin cures.

Along curved edges, however, square pixels create a jagged edge – what the industry often refers to as “stair stepping.”

As the size of printed objects and build volumes increase, stair stepping becomes more pronounced.

ETEC printers use patented pixel-shifting technology to move pixels at the edge of parts half a pixel in both the X and Y directions, cutting stair-stepping by half and delivering significantly improved surface finish.

Smooth surface finish with Pixel Tuning

Anti-aliasing technologies are ubiquitous today — used virtually everywhere digital images appear, from cell phones to TV screens and more.

ETEC brings the same technology to the 3D realm by using anti-aliasing techniques at the edge of print layers to improve surface finish. Since voxels grow from the center of a part to the edges, applying less power to these outside pixels ensures they only grow to the desired edge of the part and not beyond. (Less power = slower polymerization growth)

Called pixel tuning, that process dramatically reduces pixelation on the edges of parts, resulting in a surface finish that requires little to no post-processing.

Smooth surface finish with CDLM and Top-down Printing

https://etec.desktopmetal.com/wp-content/uploads/2022/02/top-down-1-1-1.mp4

Most forms of DLP require each layer to be peeled off the film between each layer as the build plate moves up. As each layer is peeled, a small lip is formed on the part, which roughens the surface finish.

The patented CDLM process of the Envision One and top-down printing of the Xtreme 8K eliminate the need for peeling. With no peeling, lipping does not occur, resulting in a significantly better surface finish than other DLP processes.

During top-down printing, parts are fully submerged in the resin. With the parts supported by the resin, fewer support structures are needed, ultimately resulting in a better final surface finish.

High Throughput

High throughput via Large Build Volumes

With a variety of build volumes, ETEC DLP printers are capable of printing a wide variety of part sizes, from large single parts to high volumes of smaller parts in a single build.

Since build times are entirely dependent on Z-axis height, having large build volumes in the X- and Y-axes allow for potentially thousands of parts to be printed at once, in the same time required to print one part.

High throughput via Faster Polymerization

DLP build times are determined by Z-axis height because much of the print time is related to the time it takes to cure, or polymerize, each layer.

ETEC’s DLP technology enables the fastest layer polymerization through the use of the highest-power projectors and a highly efficient optical train.

By allowing for shorter exposure times per layer, ETEC systems ultimately deliver shorter print times and higher throughput.

High throughput via CDLM or Top-Down Printing

https://etec.desktopmetal.com/wp-content/uploads/2022/02/MS_DM_EnvisionTec_E1_CDLM_1080-1.mp4

Many forms of DLP require each layer to be peeled off the film as the build plate moves up between layers. This peeling takes time and must be done slowly to ensure parts are not damaged.

The patented CDLM process of the Envision One and top-down printing of the Xtreme 8K eliminate the need for peeling, reducing the time needed to print each layer and overall print times.

High throughput via Lights-Out Manufacturing

https://etec.desktopmetal.com/wp-content/uploads/2022/01/MS_DM_EnvisionTec_X8K_320_v043. mp4

Get the most out of your ETEC DLP system with high throughput, 24/7 manufacturing designed to rival the volumes of traditionally-manufactured plastic parts.

An automated system for lights-out manufacturing and a dashboard for monitoring all operations and remote control of each machine, further increase uptime for each system.

Superior Part Properties

Superior part properties with New Backbone Chemistry

For decades, polymer 3D printing has been used for prototyping and tooling applications, but the technology hasn’t been widely adopted for the production of end-use parts.

One key to unlocking those end-use applications is the ability to create long-chain molecules in printed parts, resulting in significantly improved material properties, including isotropic strength – a key factor for many end-use parts.

ETEC printers and the DLP process include a number of hardware features – including high-powered projectors, custom-designed optics that minimize power loss– ensuring the creation of those long-chain molecules.

Superior part properties with Isotropic Material Properties

Isotropic material properties are essential for end-use components, but until recently have rarely been achievable with polymer 3D printing.

With FDM printing, very weak mechanical – not chemical – bonds form between each layer, resulting in anisotropic properties, or greater weakness along the Z axis than on the X or Y axes. This lack of uniformity has long kept FDM parts from being used as end-use parts.

With DLP printing, by comparison, each layer is left in a slightly uncured state, allowing it to chemically bond with the next layer as it prints. That bonding helps to create long chain polymers throughout parts, resulting in truly isotropic parts which are strong enough for end-use applications, and rival the properties of injection molded parts.

Superior part properties with 385nm Wavelength

All UV-curable resins require the addition of photoinitiators to start the polymerization process. Resins cured with 385-nm wavelength light require significantly less than many other materials, because the 385-nm wavelength is where absorption peaks for most common photoinitiators. Limiting the amount of photoinitiator in a part is particularly important for clear materials, because higher concentrations of photoinitiator result in parts with a yellow tint.

Quality Materials

Quality materials via Industry-Leading Material Suppliers

ETEC is determined to provide its customers with the best materials in the 3D printing industry. To do it, they utilize a world-class material science team to produce ETEC-exclusive materials, and partner with world-leading material suppliers. The printer systems are designed to be selectively open, giving users flexibility.

Quality materials via 190+ qualified materials

With more than 190 materials, from hard plastics to high-performance elastomers to high-temperature materials, ETEC’s material portfolio can address the widest range of applications.

Quality materials that break the stigma of resins

Though they have been available to print for decades, resins have long been stigmatized as brittle and possessing mechanical properties that deteriorate quickly. A new generation of resins is emerging to erase that stigma, and open the door to a host of new applications.

The superior properties delivered by this new generation of resins includes vital features for end use parts, including mechanical properties that remain stable over time, highly ceramic-filled materials for added toughness and improved surface finishes, and high-temperature materials without brittleness, which are ideal for demanding environments.

In addition to those materials, ETEC offers resins with high wax content, making them ideal for casting jewelry and other products.

Easy To Use

Easy to use Software-Controlled Workflow

https://etec.desktopmetal.com/wp-content/uploads/2022/02/materiial-switch-1.mp4

With the ability to swap between any of ETEC’s 190-plus materials in just minutes, users can tailor their material choice to each specific application.

All ETEC materials come in a single pot, with no two-pot mixing required, simplifying the process of adding resin to the printer.

While the short shelf life of many competitor resins means they must be used within hours of being opened, all ETEC materials feature shelf lives of more than a year, ensuring no material ever goes to waste.

· Key Features

High-speed continuous printing

Finish an entire 3L build volume in just 4. 5 hours – 30% faster than competing systems and 10x faster than desktop SLA.

Best-in-class part performance

The Envision One leverages long-chain polymer chemistry to produce strong, stable parts. The result is isotropic parts suitable for end-use applications and capable of standing up to the most demanding conditions.

High accuracy and resolution

Featuring patented “domeless” printing technology, the Envision One eliminates any concerns about how “doming” may impact accuracy on the Z axis. High-resolution (60 um XY) printing and patented pixel tuning technology make it easy to create fine features and smooth surface finishes suitable for end-use parts.

· Feature 1

High-speed continuous printing

The cDLM process allows for continuous printing without the need to peel each layer off the film after it is polymerized.

A ‘dead zone’ is formed by flowing a thin layer of oxygen above the film of the printing bed. Within this ‘dead zone’ the polymerization process is inhibited ensuring the layer being printed adheres to the layer above and not the printing bed film. This ‘dead zone’ is what enables continuous printing, where the build plate can continually move in the Z axis, leading to faster, more reliable prints.

Made Possible By:

Patented CDLM print process

Patented domeless print basement

· Feature 2

Best-in-class part performance

The Envision One cDLM produces end-use parts with properties that meet or exceed that of traditionally manufactured plastic components, such as injection molded plastics

Unlike most plastic additive manufacturing methods, parts created via CDLM are made up of entangled long-chain polymers, making them fully isotropic. This is vastly different from processes like FDM, which create anisotropic parts with few, if any, polymer chains between each layer. To create those long-chain polymers, printers must be able to process highly viscous resins which require large amounts of power to polymerize. Their high viscosity means these resins cannot be jetted (PolyJet), and would take too long to process with vector based polymerization methods (SLA).

Made Possible By:

Long-chain molecules

Isotropic material properties

High-power projector

· Feature 3

High-resolution printing

The Envision One cDLM delivers best in class part resolution and accuracy to print incredibly crisp features and hold tightest tolerances.

DLP is known for having incredibly high resolution parts and the EnvisionONE CDLM takes accuracy to new heights.

By using industrial DLP chips, verus cheaper consumer grade chips, and a custom designed optical train enable high contrast and minimal distortion for the projected picture resulting in accuracy down to the micron level.

The cDLM domeless printing process eliminates the “dome” effect to deliver incredible Z accuracy.

Made Possible By:

CDLM domeless printing

Industrial DLP chips

Custom-designed optics

· Feature 4

Easy to use software

The brains of the Envision One cDLM is EnvisionONE RP which streamlines the entire fabrication process, ensuring optimal part orientations, print settings, and printer productivity.

Intuitive, easy-to-use Envision One RP software automates support generation and part orientation, while an integrated file repair tool patches meshes and readies the parts for print. Cloud software allows users to remotely manage the system, send jobs to multiple printers and monitor job progress, while over-the-air software and firmware updates ensure users have access to the most up-to-date tools and processes.

Made Possible By:

Build it print profiles for each material

Automated support generation

Optimized part orientation calculator

New EnvisionTEC cDLM technology makes precision casting a matter of five minutes

News

Recently, EnvisionTEC introduced a new amazing technology cDLM or Continuous Digital Light Manufacturing (“Continuous Digital Light Processing”), for which it has already filed a patent.

The presentation took place at the international exhibition of jewelry and watches JCK Las Vegas, which runs from 3 to 6 June.

The first cDLM-powered 3D printer, dubbed the Micro Plus cDLM, was designed for precision jewelry casting and completes set tasks in minutes, not hours. The company demonstrated its capabilities to the visitors of the exhibition, right before their eyes, growing products from industrial injection molding material for 3D printing of its own PIC 100 and QView polymer, which currently cures faster than all EnvisionTEC materials.

“The advent of the Micro Plus 3D printer based on continuous digital light processing technology could be a turning point for the jewelry industry,” says EnvisionTEC CEO Al Siblani. “It usually takes a few hours to make a 3D printed molded material like our PIC 100. With the opening of cDLM, wedding bands are designed, manufactured and pre-cast in one day, which is a huge advantage in today's jewelry market. ”

On average, the Micro Plus cDLM grows 2.5 cm in the Z-axis in 10-20 minutes depending on the media selected, with the full working volume of the printer (45mm x 28mm x 75mm). The Micro Plus cDLM uses the same industrial UV LED light source. It also has a built-in PC with Wi-Fi and a user-friendly touch screen.

“The focus of our R&D team is to find real solutions to existing problems,” Siblani adds. “By adding the speed capabilities of continuous digital lighting technology to our range of services, we are ready to offer our customers the highest level of service in the jewelry market.”

Micro Plus cDLM will begin shipping in August 2016.
