Desktop Metal, Inc., a global leader in additive manufacturing technologies for mass production, has expanded its partnership with Henkel on the development of photopolymer materials, beginning with the qualification of Loctite 3D IND405 Black and Loctite 3D 3843 from Henkel for use on the Xtreme 8K, the world’s largest digital light processing (DLP) printer for high-volume production of end-use parts.
Loctite 3D IND405 Black and Loctite 3D 3843, two popular engineering materials in the 3D printing industry, are both stiff, strong and durable, making them ideal for a wide range of manufacturing parts use final and consumer goods. Parts produced in IND405 have exceptional impact resistance and can be machined, tapped and polished.
Loctite 3D IND405 and 3843 are already offered in the ETEC Envision One desktop DLP printer, as well as high temperature photopolymers (Loctite 3955 HDT 280 FST, IND 147 and IND 406), elastomers (Loctite 475 and IND 402) and Loctite Med 413, a biocompatible plastic used for medical devices and equipment.
Now customers will be able to print Loctite 3D IND405 and 3843 on the Xtreme 8K, which features a build area of 450 x 371 x 399 mm (17.72 x 14.61 x 15.71 inches). This new combination of material and large build platform will allow users to deliver all new part sizes and throughputs without tooling.
“Our team is thrilled to partner with Henkel and offer its Loctite materials on our truly differentiated DLP printing systems,” said Ric Fulop, Founder and CEO of Desktop Metal. “By printing Loctite 3D IND405 HDT50 High Elongation and Loctite 3D 3843 HDT60 High Toughness on the ETEC Xtreme 8K, manufacturers will be able to produce on-demand end-use parts in all-new sizes and at higher throughputs. which help reduce the per-cost of the part.Plus, they won’t have to pay or wait for tools to get the job done cheaply.
“A while ago I saw the Xtreme 8K before its release and knew it would excite the industrial additive space with the large build volume. I’m pleased with the work our teams have done to bring Loctite resins to platform with initial workflow validations,” added Sam Bail, Head of Business Development and Partnership Management for Loctite 3D Printing at Henkel.
DLP harnesses the power of light from a projector to cure liquid resins into layer-by-layer part designs, one rapid flash at a time. It is one of the most mature 3D printing methods, and has been used for high volume manufacturing for years.
While most DLP printers feature a projector below a build plate, where parts must hang from a build plate while they are printed, makers interested in high throughput have begun to appreciate the challenges of this approach to DLP. Extremely large parts, especially those with heavier or elastomeric properties, are difficult to suspend from a build plate. This build strategy also requires more support structures that need to be removed, a challenge when dealing with a higher volume of parts.
The ETEC Xtreme 8K, which is already used to make end-use parts for consumer goods, is one of the few commercially available top-down DLP printers in the 3D printing industry, with dual projectors industrial suspended. The different approach allows extremely heavy parts to be 3D printed on a tray in a vat with thicker viscosity materials. This simplifies workflows, as parts do not require mechanical removal from the build plate.
Additionally, this approach allows light or energy from the projector to penetrate directly into the photopolymer, eliminating the barrier of a plateau that exists in bottom-up DLP printing. This makes it possible to process different types of materials, which can offer new properties.
In addition to Loctite IND405 and 3843, the Xtreme 8K prints an entirely new class of durable, high-strength DuraChain photopolymers that provide two-part material strength in one pot, such as FreeFoam, Elastic ToughRubber and Soft ToughRubber. DuraChain materials are available exclusively on ETEC printers.
