Intro
Awesome 3D printer that uses lasers and resin to print, rather than heat and filament.
Rules
- Please donate $0.25 per milliliter or per gram of resin, whether or not the print succeeded. This covers both replacement cost of media, and maintenance costs.
Instructions
Model Prep
- Get an STL file of your model
- Use MeshMixer to shell the model
- Printing solid objects is liable to fail
- The only thing that sticks the part of the bed, versus the bottom of the vat, is a differential in surface area
- Add support material as needed in MeshMixer as well
- Export an STL of the modified file from MeshMixer
Slicing
- Import your model into RetinaCreate
- Use RetinaCreate directly to send the job to the printer over the network
- The job will be transferred in full to the printer prior to printing
Printing
- Go to the printer
- Keep in mind that the resin is exceedingly sensitive to blue-to-UV light
- Turn off all the lights in the Fab Lab, and close the door
- Turn on the red light over the printer using the standard wall switch (as opposed to the strike plate/motion sensor)
- Open the cover and remove the yellow acrylic vat cover
- Carefully fill the vat to the middle of the three steps on the fill indicators in the rear corners
- Close the cover and tightly close the resin bottle
- Use the touchscreen to acknowledge that you have added resin, and to start printing
- Once the cover is closed, you can turn the room lights back on
- Keep an eye on the printer--it will pause for resin refill every 50mL or so of resin
Finish
- Several hours after the job started, it will be finished
- Keep in mind that the resin is exceedingly sensitive to blue-to-UV light
- Turn off all the lights in the Fab Lab, and close the door
- Turn on the red light over the printer using the standard wall switch (as opposed to the strike plate/motion sensor)
- Put on nitrile gloves
- Open the cover and gently remove the print from the bed with a metal scraper
- Put the yellow acrylic plate over the vat and close the cover
- Once the cover is closed, you can turn the room lights back on
- Soak the print in isopropyl alcohol for around 15 minutes
- Rinse off the part under a lot of warm water
- Put the part in a container full of water
- Put the container under the EPROM eraser
- Do not look into the EPROM eraser when it is on
- The part will probably be fully cured in a few minutes--check it regularly, and stop curing once the part is no longer tacky
Maintenance Info
Daily
- Gently scrape off resin from build plate
- Wash off vat cover if needed; dish soap and hot water work OK
Weekly
- Ensure bed is level and calibrated.
FAQ
@Liz on slack is available to answer questions on operating this machine, she has the most experience on it.
ToDo
- Mechanical mounts for beaglebone to front panel
- 1-2" vent ducting to main vent
- Edit firmware to make prints take less time
- Laser calibration to try fixing edge non-linearity
- Replace hood
- DC power switch
