$10 Top Down Build SLA. Testing for Bottom Up Build
Posted: Wed Mar 11, 2015 11:39 am
Hey guys,
Just did some testing this weekend on my new printer that I put together. I wanted to quickly throw something together to see what SLA is all about and also to see if my projector works without any modification. Turns out it does ACER 5360 720P. I did have to remove the focus screw so that I could pull out the focus wheel more and focus on to my build plate. I still need to fine tune the focus. I'm using FTD Standard RED
How I print:
I don't have a Z axis Limits so I just set my build plate slightly above the resin surface with some resin poking out of my perf board holes. I then start my print.
8 Second Exposures on first 3 layers
2.5 Second Exposures on all other layers.
Printing at 0.05mm/Layer
Parts:
Arduino Uno $5 (Ebay) - Running HTL's Code. Super simple code. I made some slight modifications to it.
A4988 Stepper Driver $2(Ebay) - Soldered directly to the pins and shrunk tubed the whole thing. Added connectors so I can remove it easily. Running at 1/16 Micro Stepping
Glass Vat $2 (Dollerama) - Nice thick glass and its square. Perfect size for what I wanted to acomplish
DVD Drive Laser Rail $1 (Ebay) - Got 10 Broken DVD drives for $10 on ebay. Took it apart for just the rail.
12AWG wire and Perf Board which I had used for build plate.
Below are some pictures:
