This add-on module is expanding the capabilities of FABtotum’s already impressive all-in-one machine.
You may recall FABtotum from the recent crowdfunding campaign for its low-cost, all-in-one fabrication device capable of 3D printing, scanning, CNC milling and engraving. Following the incredible success of the ATmega1280 powered machine, the Italian startup has returned to Indiegogo with an integrated SLA 3D printing platform.
Dubbed PRISM, the 6.5mm thick module will expand the FABtotum personal fabricator’s functionality by bringing high-resolution, stereolithography-based manufacturing to the desktop of Makers. The add-on features a swappable laser head along with a removable resin vat that can easily be mounted to the printing bed.
With PRISM, Makers can 3D print in a wide range of filaments including the ordinary PLA, PETG and ABS, as well as more advance materials such as nylon, brass, wood and aluminum. Aside from that, its built-in high-res camera, touch probe and laser allow users to acquire 3D point clouds and models via multiple 3D scanning methods.
“PRISM is a new manufacturing technology that merges the advantages of Selective Laser Synthering (SLS) with the precision of Digital Light Processing (DLP). Most DLP printers relies on integrating commercially available DLP home projectors wich are expensive and are not designed for 3D printing,” the team writes.
Resin is cured by shining a light with the right wavelength through an LCD matrix. Whereas similar systems use a simple yet expensive UV LED array, PRISM employs a a mirror and a set of collimated light emitters. This reduces the amount of energy consumed and tremendously speeds up the solidifying time.
Impressively, the PRISM can also produce an unprecedented level of detail at around 80µm in XY and 0.47µm in Z.
Like with the rest of their products, FABtotum has made the module entirely open source and encourages feedback from the Maker community to help further improve the platform and solve any issues.
