EnvisionTEC will now offer XY resolution of 25 microns ― equivalent to about half the cross-section of a human hair — in two of its largest 3D printers:
The improved performance is made possible with a new FPGA (field-programmable gate array) control that allows EnvisionTEC to turn its laser on and off in the Y scanning direction with lightning-fast speed.
“With this hardware upgrade, EnvisionTEC can now offer the same level of resolution in our 3SP family that we are known for with our Perfactory printer family,” said CEO Al Siblani.
A demonstration board 3D printed on a Vector UHD 3SP will be on display this week in Fort Worth, Texas, at Rapid + TCT, the premier event for 3D manufacturing in North America. EnvisionTEC will also be showcasing other new 3D printer and material innovations in Booth 1304.
The recent hardware upgrade makes 3SP printers an ideal choice for applications requiring high accuracy, fine detail or ultra-smooth surfaces, such as medical devices, parts with fluidic chambers, tooling for molds, large investment casting patterns and detailed prototypes.
About 3SP Technology
Launched in 2013, EnvisionTEC’s patented 3SP (Scan, Spin and Selectively Photocure) technology uses a unique laser-based process to cure photopolymers in a large vat.
While conventional SLA systems use an expensive solid state laser to draw out parts layer by layer, often reflecting the beam off galvo mirrors in a large build area, the 3SP approach is simple and efficient.
A multi cavity diode laser is reflected off a spinning mirrored drum that can efficiently scan across a very large vat to cure material. Essentially, the laser draws in straight lines in the Y direction, with the beam simply turning on or off to cure the necessary shape as the complete laser assembly moves in the X direction.
A white paper detailing how 3SP is superior to SLA for manufacturing and production can be found at EnvisionTEC.com/learn3SP.
Adoption of 3SP continues to grow as knowledge about the technology and portfolio of materials expands. The 3SP line is popular among dental laboratories printing large volumes of dental models, but users also include manufacturers in a variety of industries, including medical devices, automotive, aerospace, consumer goods and more.
