SLA
Key Points:
- Industrial (vat) SLA is not equivalent to desktop SLA: peel forces are completely eliminated and even the forces of gravity are countered by buoyancy, negating the needs for dense or thick supports and better ensuring true to CAD accuracy.
- Max single part build volume of 15x15x10" on our Projet 7000HD machine.
- Metal threaded inserts can be added for durable mounting points -- and are always kept in stock.
- Aesthetics are generally top-notch out of the machine, but appearances can be enhanced with minimal amounts of work as needed (wet sanding, paint, clearcoat, etc.).

SLA is a 3D printing technology invented by 3D Systems in which photosensitive resin is selectively cured with a UV laser. Layers are typically 100um (0.004") thick. Due in part to the high layer resolution and also the extreme precision of the laser system and the nature of SLA resin itself, SLA prints are among the most aesthetically pleasing of all our systems.
POP currently offers Accura Xtreme (grey) and Accura ClearVue (clear) materials. |
MATERIAL & COLOR OPTIONS
Due to the nature of SLA printing (in that full ~100kg vats of resin are needed), material options are limited. At this time, POP offers the following material options:
- Accura Xtreme (grey)
- Accura ClearVue (clear -- but not optically clear as-printed)
FINISHING OPTIONS
SLA prints, like Polyjet prints, usually look pretty great right out of the machine. Please note that small white spots/scuff marks can be normal on SLA prints, as they occur during the cleaning and post-cure processes as the supports are removed and the parts are handled. If exceptional finishes (or clarity in the case of ClearVue material) are needed, models can be wet sanded and polished for an even smoother surface, or painted for a precise match with other components in your assembly.
