4. Check the model every 15 minutes to evaluate its progress. It may be necessary to adjust
the heater control up or down slightly to maintain the bath within the ideal de-waxing range
of 50°C - 55°C without exceeding the 55°C maximum bath temperature. It may also be
necessary to flip or rotate certain designs to facilitate faster, more efficient de-waxing.
(Tweezers are a good tool for this.)
5. De-waxing is complete when the last residue of 3Z Support has dissolved off the model.
The slowest sections to dissolve are those that are in the least amount of contact with fresh
VSO, e.g. deep holes, channels, corners, etc.
6. It may be necessary to rotate or turn over certain models in order to allow them to de-wax
completely. Do this gently using tweezers or tongs or by hand (Wearing gloves is
recommended.)
7. Periodically during the de-waxing process lift the strainer out of the bath to inspect the
models. It is recommended also to raise and lower the strainer in and out of the bath a few
times in order to rinse the models of any debris that may be accumulating in the basket or
on the models.
8. Once the model is free of 3Z Support, gently remove the model(s) from the VSO bath and
place it on a paper towel to dry. (Small tweezers are a good tool for this.)
9. Turnoff the Heater Stirrer device unless you have additional models to de-wax.
10. At this time the models can be cleaned using soft bristled brushes and/or compressed air
depending on the robustness of the model geometry.
11.5 Post Processing Tool Kit Suggestions
 Soft brushes of various sizes (¼”, ½” and 1” wide) with natural bristles for general parts
cleaning
 Pipe cleaners (1 package) for cleaning small holes
 Small picks (dental style probes) for cleaning small holes and tight spots
 Syringe bulb (2” diameter “rubber” material) for spraying heated solvent in holes and
tight spots
 Alcohol swabs for cleanup and polishing parts
 Clear acrylic nail polish for mending and gluing parts
 Soft shop paper towels for cleanup and drying
 Wire strainer to isolate small parts in solvent bath
 Canned or compressed air to blow off excess solvent
 Rubber gloves (100 nitrile medical exam gloves) for working at length in solvent
 Magnifying glass or 10X eye loupe for inspecting parts and offset calibration results
 Drill bits (various sizes- size 16 to ¼”) to remove wax material from models
11.6 Model Evaluation
1. Use the following factors to evaluate model quality performance:
a. Printhead offset calibration is successful: Result is a good surface finish
b. Printhead volume calibration is correct: Result is sufficient build and support material in
the model, e.g., no voids on top surfaces or ‘spikes’ on bottom surfaces.
