Removing the Build Platform

  • When the model has finished printing, wait at least 10 minutes to allow excess resin to drip out before opening the lid.
  • Insert a 9.5"x14.5" cutting board and place it on top of the vat. Always insert the cutting board before removing the build platform to avoid dripping resin inside the machine.
  • Remove the build head as described Part 2: Getting Started.
  • Rotate the platform to face upward or hold a container under the platform to catch any resin.
  • Scrape excess resin off the build platform into the tray before transferring to the finishing station.
  • Make sure you keep the cover closed to protect the resin from external UV light.

Finishing Steps

General Steps

  • Transfer the platform to your self-prepared finishing station.
  • Use the corner of the paint scraper to release some part of the base of your model, then remove the whole model. The scraper may be sharp. Please be careful not to hurt yourself. Sometimes you may find it useful to use a rubber mallet in conjunction with the scraper to remove the part.
  • To rinse excess resin from the model, fill your container with 99% Isopropyl Alcohol (IPA) and place your model inside. Let it soak for 15 minutes. You may try holding the model with tongs and swirling the model inside the container filled with IPA to remove any loose resin. We recommend you cover the container with a plate to prevent excessive evaporation of the IPA.
  • Take the model out of the IPA using the tongs after soaking for 15 minutes.
  • Remove the supports carefully.
    • Use the flush cutters to snip away supports or chisel them away with the paint scrapper and rubber mallet.
  • Put the model on some paper tissue to dry.
    • You may use 220-1500 sandpaper to sand away any unwanted marks after the model is fully dry.
    • Clean sanding dust from the model with IPA.
    • You may want to clear-coat or paint the model as desired.
  • Wash the build platform with IPA. Allow to dry. You should wash the platform right away after each print. Leaving it exposed to air will make it very hard to clean later.
  • Do not wash the vat with any chemicals. Cleaning the vat with alcohol may cause it to crack.
    • You don’t need to wash the platform if you use the same resin for your next prints. In this case, put the platform back in the printer right away.


  • Printed objects are by design cured to about 90% strength to extend the useful life of the non-stick layer of the vat.
  • To cure fully, you may place the models in sunlight after cleaning them.
  • Placing models in sunlight to cure may cause the models to turn slightly yellow as sunlight contains a wide spectrum of light that breaks down color additives in the resin.

Repairing Imperfect Prints

Follow instructions below to repair imperfect models. Repair can only be done for small holes or fractures.

  • Prepare: A toothpick, resin, natural sunlight (or a 405nm laser pointer), 220-1500 grit sand paper.
  • Dip the toothpick in the resin and fill the hole completely with the resin. Try to be accurate in order to reduce sanding afterwards. Do the same to glue parts and put them together.
  • Leave the model in the sun to cure. You may instead use a laser pointer, which is faster.
  • Once fully cured, sand the area to create a smooth surface. Wash with IPA to clean off any dust.
