COLOR ENHANCEMENT
Now that the part is thoroughly cleaned, certain post-processing methods can be used to enhance the color if desired . There are
two (2) methods of post-processing: Solvent Wash and Wax Dip . Be sure to weigh the pros and cons of each method and the
desired outcome of your geometry .
METHOD 1: SOLVENT WASH
•
SAFETY NOTE
1: Work in a well-ventilated area. Do not perform this process in a small confined unventilated area.
•
SAFETY NOTE
2: Always use gloves and safety glasses when working with solvents .
•
SAFETY NOTE
3: IPA 99% is a highly flammable liquid; it has a very low flash point of 12°C. Keep away from any possible
ignition source .
Pros
•
Best Surface Finish
•
Simple
•
Fast
•
Good for bulkier parts
•
Good for parts with small holes or "caves"
1 .
Fill a container with enough solvent to fully submerge the part .
• We recommend
Isopropyl Alcohol (IPA)
NOTE: Rubbing Alcohol is typically 70% IPA and 30% water . IPA 70%, and IPA 50% will bring out color in the
parts, but not nearly as effectively as IPA 99% or IPA 91%
Wearing gloves, submerge you model in the solvent to cover all of the surface area for just a few seconds .
2 .
Dip the part in IPA 99% . Fully submerge the part, covering all surfaces evenly with IPA 99%

Cons
•
Requires ventilation
•
Small features may dissolve, deform, or warp
•
May cause color distortion on monochrome
parts .
•
Can bind/lock moving parts .
for a solvent as it is easily attainable, relatively safe, and works well .
