Post-Processing Guide for Support Material Removal

This guide provides the standard procedure for removing support material. Actual results may vary slightly based on specific conditions.

Preparation:

Ensure the following items are ready before starting:

1. Magnetic Agitators
2. Isopropanol (99%)
3. Protective Glasses
4. Beakers- 1.65 Liter
5. Dust Masks
6. Wire Mesh Basket
7. Rubber Gloves

Note: Ensure the de-waxing area is well-ventilated or equipped with a ventilation system.

Procedure:

1. Softening the Support Material:

   • Place the build plate on the heated platform of the magnetic agitator.
   • Carefully remove models one by one as the support material softens. 
   • Note: Wear protective glasses, a dust mask, and rubber gloves before handling.

2. Isopropanol Baths for Cleaning:

   • Prepare three separate beakers, each filled with 99% isopropyl alcohol, and place them on a heated magnetic stirrer.
   • Maintain the temperature below 37°C in all baths.
     • The first bath removes the majority of support material.
     • The second and third baths are for rinsing and final cleaning.

3. Model Immersion:

   • Place models in the wire mesh basket, avoiding overstacking to prevent collisions.
   • Lower the basket into the beaker, ensuring it maintains a safe distance from the stirrer.

4. Adjust Stirring:

   • Start stirring at a low speed, gradually increasing to enhance cleaning. Avoid overly high speeds to prevent model movement.
   • Check the dissolution level of support material every minute.
     • Note: As alcohol becomes saturated, its effectiveness reduces. It is recommended to dissolve no more than 100-120 grams of support material per liter of alcohol.

5. Rinsing:

   • Remove models as soon as the support material is fully dissolved; do not leave them immersed for extended periods.
   • Place the models in the second bath for 2-10 minutes for rinsing.
   • Transfer models to the third bath for an additional rinse of about 20 seconds.
     • Note: Use a thin wire or tweezers to handle delicate wax objects.

6. Drying:

   • Dry the cleaned models using a small air gun or allow them to air dry. Place them on a paper towel or cloth to absorb any residual alcohol.
