This is my project.
I have designed a TOP DOWN resin printer.
It uses a projector to project the slices onto the resin surface
I tried getting hold of the Chi tu controller board, but they are discontinued.
Will it be possible to control the slices via the projector onto the resin bath using an arduino Mega?
I can use the various slicing software like Chi Tu Box
Kind Regards to all
Most anything would be possible. You, yourself, has to be capable of doing it. The first clue is having to ask if something is possible.
Yes , I figured it out. I will simply just write my own program in Delphi to time and display the images. The projector will be connected as the second screen output to receive the "slide show".
The arduino board will control the Z axis.
This is such a simple solution. Found it here:
Good! Let us know the results.
I also want to see the results.
Progress so far:
- Wrote a Delphi program to "print" the slices to the projector.
- Arduino will do the progressive lowering of the build plate at my settings ( After every 6 seconds of projector exposure, the stepper will lower the build plate 200 microns (will increase or decrease after experimentation).
- Busy building the 1M x 1 M x 1M bath.
- The bath will require 1000 liters of resin.
This is beyond my budget. So I tried to fill the tank with close to a 1000 litres water and floating a 2mm layer of resin. It failed and all fell to the tank bottom. I tried to increase the water density with a salt mixture. IT WORKED!!!!.
The resin layer floats beautifully on the surface. 5 days so far and still floating.
Final task now is to devise a system to continuously float a 2mm layer on the surface. I have some idea like the "pigeon feede3r system" but could do with some suggestions.
Once the project is completed I will post a video.
Keep well all!
