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, 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.

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AnyCubic slicer is basically a customized and slightly outdated version of CituBox, better to get the newest version from:

Support:

Auto support does some ground-work but needs quite some lay on hands.

  • Minimas
  • local minimas,
  • edges
  • "Enough" to resist the suck and the 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
  • Drainage: Air-holes and drain holes.
  • 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

Checking and refilling the 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 resitance
    • if there are resitances, empty the vat and use the rubberscraper to remove any stuck resin.
  • Cleaning the build plate:
    • Use the metal spatula to remove any stuck resin

Finishing the printed object

  • 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 prewash 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!
