Compact and ultra-precise MSLA 3D printer for both beginners and professionals. Completely open source.

Oliver uses a mask stereolithography technology (MSLA) to create detailed and precise objects. UV light is shined through a mask and then absorbed by a photopolymer resin. This liquid resin solidifies when exposed to strong UV light. The object gets build layer by layer.

Such process has several advantages compared to traditional FDM machines, namely increased precision, speed and reliability.


Oliver has XY plane resolution of 47.25 microns (thanks to 2K LCD  – Sharp LS055R1SX03) and Z axis resolution of 25 microns. This is way more precise than any consumer FDM 3D printer.


Thanks to MSLA technology Oliver can print one layer in just 20 seconds[1].

Despite being an amateur device, Oliver was designed to be a reliable workhorse. We have developed custom electronics and cooling system to improve reliability. Aditionally, most parts are easily swappable.
