[Video] 3D Print Custom Parts Without 3D Modeling!

There is just one week left in the campaign! First of all, I want to thank you very much for your support. I am very happy about the reception of the campaign, and I hope that the kits that will be delivered fulfill all your expectations. In this update we show the manufacture of a keychain based on an image with the text “Thank you!”. Lite3DP allows the possibility of “hacking” the sections that we print (unlike most current MSLA 3D printers, which use a print file without modification possibilities). Click through to the full update for details and a tutorial video. Read the full update.

Here's a brief history of how I came to design the Lite3DP S1. Read the full update for more. Read the full update.
