About LittleRP

Meet the LittleRP, an affordable, flexible, and open 3D resin printer that lowers the barriers to entry for those looking to get into the exciting world of stereo-lithography printing.

The LittleRP has been designed from the ground up to simplify the resin printing process. Our focus on smaller high quality prints means complicated peeling mechanisms are not required.

Being open is one thing, but we wanted to make the LittleRP easy to self source. Lasercut materials and standard T-Slot extrusion means building your own from scratch, or simply modifying an existing LittleRP is an exercise you can take on yourself!
Inexpensive quality stereo lithography prints are possible thanks to the use of high quality components such as linear slides and integrated leadscrew steppers. The LittleRP might be inexpensive but corners were definitely not cut
