Dirty cheap 3D printer base on TFT ,If the cost of resin is not included, the whole machine costs less than $40. Work is ongoing and is expected to end in March 2019.
Thank you for your reminder. We got this idea on November 21, 2018 and signed up for the competition in the Arduino open source community in China. Sean Hodgins has done a good job, and my partner and I feel a little frustrated at the news. We will continue to open source. Thank you again for your attention.
Interesting - did you see Sean Hodgins' resin-printer-in-a-Christmas-ornament build (https://hackaday.com/2018/12/24/have-yourself-a-recursive-little-christmas-ornament-that-prints-ornaments/) from a couple weeks back? Looks like you're both on the same page.
