Post-print steps

This tutorial will walk you through the steps to remove and clean your printed part and prepare Ember for the next print.

Process overview:

  1. Remove your model
  2. Rinse your model in IPA
  3. Post-cure your model with a UV lamp
  4. Clean the build head
  5. Clean the resin tray

Step 1: Remove your model

  WARNING When handling resin, always wear protective gloves, protective clothing, eye protection, and face protection.


  1. Remove the build head by rotating the locking lever counter-clockwise
  2. Place the long edge of the build head onto the cutting mat
  3. With one hand, clasp the build head by the protruding section, making sure that your hand and fingers are behind the build plate
  4. In your other hand, take the scraper and gently remove the part from the build head



Improper use of the scraper could result in a gouging injury to your hand that's holding the build head.

To prevent injury, always keep your fingers and hands out of the line of motion of the scraper, as shown.

NOTE: If your model contains nested cavities, use a can of compressed air (such as this) to blow away the residual resin from within these spaces before rinsing your part in IPA. This will enable the IPA to clean the internal surfaces.

Step 2: Rinse your model in IPA 

  1. Place the printed parts into a container of isopropyl alcohol
  2. Gently shake the container and allow it to soak for 5 minutes
  3. Remove the part and leave to dry

NOTE: Models with complex geometries (e.g., nested cavities) may require rinsing in a second bath of IPA for an additional 5 minutes, in order to clean away all of the liquid resin. Therefore, we recommend doing this second IPA rinse, soaking for a total of 10 minutes.


DANGER Keep isopropyl alcohol away from heat, sparks, open flames, and hot surfaces.

Your part is now ready for supports to be removed and to finish.

Step 3: Post-cure with UV lamp 

Use a UV lamp (such as this model) to post-cure the part for at least 5 minutes. This will help to create an optimal surface finish by removing any tackiness and assuring the there is no residual liquid resin on the model. 

NOTE: Models with nested cavities require a longer post-cure time. If your model has internal holes, you may need to expose it to a UV lamp for up to 30 minutes in order to cure any residual liquid resin on the model.

Step 4: Clean the build head

After removing the printed part you should clean the build head so that it is ready to be used again.

  1. Using the scraper, remove any supports or other cured resin that is on the build plate
  2. With a paper towel dipped in isopropyl alcohol, wipe anyway any excess resin
  3. Return the build head to Ember

Step 5: Clean the resin tray

As a general rule, resin trays should be cleaned with isopropyl alcohol after each use and wiped with a paper towel (except for the PDMS window, which should be wiped with a KimWipe or microfiber cloth). This is especially pertinent if you're using a non-Autodesk resin, as some of these resins can damage the tray, cure into a solid block, or cloud the PDMS window. Even Autodesk PR-48 (Standard Clear) will cloud the window, and the pigment in our PR-57 series can settle to the bottom if it's left sitting in a tray too long.

The exception to cleaning a tray after use is if you'll be using that same resin again later that day. 

To clean your tray, follow these tutorials:
