This is a draft for training material for AnyCubic Photon

What is SLA-printing

Risks and security precautions

  • Resin is mildly toxic and an allergen.
  • Use glasses, nitril gloves and only touch things inside the cabinet as soon as you have started working.
  • Wash your hands after you have removed the gloves. only Use soap and water, never use IPA or acetone to wash your skin since it does remove most of the resin it helps the rest of it penetrating deeper.
  • Lift bottles with your hand over the label

Slicing your files

Slicers and slicer settings.

AnyCubic slicer is basically a customized and slightly outdated version of CituBox, better to get the newest version from:

https://www.chitubox.com/

Support:

Auto support does some things automatically but you may need to do some manual adjustment of:

  • Minimas
  • local minimas,
  • Alternate support along edges.
  • Support density that needs to be "enough" to resist the suction forces of the layer separation and gravity.
Model management
  • Slicer works "upside down"
  • Avoid horizontal faces at all costs,
  • Avoid horizontal edges if possible
  • Try to center the model for flow-reasons
  • Hollowing: Reduces resin-use, makes curing quicker and reduces the number of supports needed.
  • Citubox: Hollow does an OK job but can cause un-supported artifacts
  • MeshMixer: and then import STL into CituBox does usually do a much cleaner job
  • If possible add a small air-hole at the top of the model(towards the build-plate) in order to avoid vacuum and that the model gets ripped of its support
  • Add a drain-hole near the bottom of the model to avoid getting resin trapped inside. It is not the end of the world but increases resin use, cure time and might look bad
  • Under exposure: Print fails or loss of small details
  • Over exposure: print gets to thick, loss of small details
  • Common errors: To few supports, missed minimas or maximas

Preparering the machine

  • Put your gloves on.
  • Insert USB-stick before handling any resin
  • Give the resin a stir and check that it flows evenly.
    • If it doesn't, filter it into the bottle and refill the trough
  • Run the _rubber_ scraper gently along the bottom and check for resistance
    • if there are resistances, empty the vat and use the rubber scraper to remove any stuck resin.
  • Cleaning the build plate:
    • Use the metal spatula to remove any stuck resin
  • refill the resin upp to 1/3 of the depth of the vat

Finishing the printed object

  • Take your USB-stick before handling any resin
  • Let the model it drip for a little while.
  • Try to get all of the resin to drip back into the vat, if there is still resin inside the model pour it out and discard before washing.
  • Run it in Resinaway, first pre-wash then final wash.
    • Resinaway is expensive but doesn't make the model as brittle as IPA, further more it isn't flammable and can be used many times
    • Unless it starts to feel goopy it is probably fine, as a rule of thumb, don't replace it.
  • Let the model sit for a few minutes on a paper-towel before moving it into the UV-chamber
  • Let it sit in the UV-box for about 20 minutes

Cleaning the printer

  • Wipe the printer and the work-surfaces with IPA, throw the ragg away.
  • If something seems to have broken off the model: Filter the resin!

The things i filmed

Here is an album with the various things I filmed.. It needs to be cut and made into proper instructional videos. https://photos.app.goo.gl/xnDX69vvJ3vtqjoa7
