  • Max Build Volume: 64 × 40 × 134mm
  • Be mindful working with resin. It's a carcinogen, which means that every time you come into contact with it, it increases the damage to your body.
  • Be gentle with the resin trays. The window can be damaged easily. Only touch it with the rubber spatula when cleaning the tray.
  • Check if your 3D object complies with the Design guidelines
  • Get the workspace ready
    • Get nitrile gloves
    • Get safety goggles
    • Get paper towels
    • Put a Silicon mat in front of the printer
    • Get the alcohol spray bottle
    • Get pots with alcohol (IPA)
    • Get resin and used resin bottle
  • Load model in Print Studio and position accordingly.
    • Uncheck the support-icon in the object browser when you want to print without auto-supports.
    • Select the actual resin you're going to use. This affects the print settings.
  • Roll the resin bottle between your hands to stir the resin without making too much bubbles.
  • Fill tray with resin. Respect the MIN MAX indications.
  • Start the printer
  • Do the calibration

Post-print

  • Open alcohol pots
  • Put an open waste basket near the workstation
  • Put paper towels next to silicon mat
  • Put on goggles and 1 glove
  • Take the print head out and remove the part with the spatula. Keep the blade parallel to the surface to prevent damage to the head.
  • Put the part in the 'dirty' alcohol pot with tweezers and shake the bottle for 3 minutes.
  • Clean the tweezers with alcohol and take the part out of the alcohol container.
  • Dry the part with a paper towel.
  • Clean the build plate and put it back in the printer.

Don't leave resin in the vat for more than 2 days.

  • Pour resin from the resin vat into the 'used-resin' bottle.
  • Clean the resin vat.
    • Do not touch the window with anything other than the yellow rubber spatula.
    • Use the yellow rubber spatula to remove most of the resin.
    • Use a paper towel soaked into alcohol to clean up the remaining resin.

It is possible to store the resin vat in the printer for medium periods of time. For longer periods, put the vat in a air sealed bag and store in a light tight cupboard.

  • stop the printer
  • filter the resin from the vat through a single use funnel
  • with the yellow rubber spatula, gently rub the window of the vat, to make sure nothing sticks to the window.
  • pour the filtered resin back in the tray
  • rethink the 3D model and or the print setup and try again.

When the object is set up in Print Studio, go to the Layout tab, select the Scale tool and select the object. The dimensions appear on the bounding box.


Note one of the dimensions and open the file in Blender. (In this case the Z-axis)


Change the units to Metric, and set Length to millimeters. Scale the model until the size matches the chosen dimension in Print Studio. (The dimension is Y in this case since the object was reoriented in Print Studio)


In the 3D-Print add-on, click the button Volume under Statistics. The volume is reported in cm3. Multiply with 1000 to get mm3.

( resin amount (in liter) * resin cost * material multiplier )
  +
( machine time (in hours) * machine time multiplier )
  • resin amount: calculate the volume of your model in a 3D application. Then calculate this amount in liters:
  • Volume of 3D model (mm3) * ( 10 to the power of -6 )
  • resin cost: €108,00 per liter
  • material multiplier: 30%: material cost *1,3
  • machine time multiplier: €0,55 per hour
  • Make sure the supports do their work during printing (not only at a completed print).
  • Orient faces that need to be clean away from the build platform.
  • Keep wall thickness in mind. It might show up fine in the slicer, but it can ruin the print. As you can see in the example: what should've been a continuous cylinder are now 4 separate walls. The wall thickness on the thinnest parts in the red circles is 0.19mm.
  • Avoid large surfaces coming into contact with the build plate. This creates suction and peeling of the newest layer. Tilt the model on 2 axes and support the islands in the slicer.

Source

  • Keep resin contamination to a strict minimum. Only the following parts can be touched with resin-contaminated gloves.
    • build head
    • spatula
    • tweezers
    • funnel
  • Keep all other parts and surfaces clean!
  • Use a silicone mat to catch resin drips
  • Wear goggles to protect your eyes from accidental splashes of resin
  • Wear nitrile gloves - (throw away after use, or clean them thoroughly with alcohol)

Necessary after

  • a failed print
  • a changed resin tray
  • a changed build head
