Product information "n-Butyl Acetate | 5L"

n-Butyl Acetate is a clear, colorless solvent with a fruity smell that is suitable for the used for speeding up the evaporation rate of PGDA Wash Solvent on 3D-printed parts.

Combine with PGDA Wash Solvent for faster post processing.

Formlabs Polyurethane Materials produce pliable and tough polyurethane parts that can withstand extreme impacts while maintaining true shape long-term. Due to there chemical composition they can only be washed with PGDA Wash Solvent. To speed up the evaporation rate of PGDA wash the part in n-Butyl Acetate.

Recommended and tested quality by Formlabs

3D-Basics is the global Solvent distributer for Formlabs. Purchasing n-Butyl Acetate from 3D-basics ensure maximum compatibility with Formlabs Resin and Machines. n-Butyl Acetate with a purity of ≥ 99% is highly effective at removing uncured resin from Polyurethane 3D-printed Models and help wash of left PGDA Solvent.

How to use n-Butyl Acetate

Always wear Nitrile Gloves when handling n-Butyl Acetate.
n-Butyl Acetate is only tested for use with Formlabs PU Rigid 650 & PU Rigid 650.

This guide is based on washing parts with PGDA Wash Solvent.
n-Butyl Acetate is used in the final step of the process.

For removing uncured Resin from SLA or DLP printed parts fill your cleaning container with the amount specified by the manufacturer. To minimize waste, it is suggested to pre-clean the parts before placing them in the cleaning container to expand the lifespan of your fresh PGDA. This can be done in a separate container with either "dirty" PGDA from previous cleaning cycles. Place the finished print in the cleaning container and clean the parts for at least 2 min or according to the material manufacturers guidelines. After the cleaning cycle, blast the PGDA coated part with compressed air and Wash with n-Butly Acetate to speed up evaporation. Let the model dry and check for a tacky surface, repeat if necessary, till the surface is not tacky anymore. If it is still tacky it might be a sign to replace the PGDA.

Optimal Cleaning stages
  1. Preclean in small container to remove uncured resin and minimize amount of saturated Wash Solvent
  2. First Stage Cleaning: Run Wash cycle in Form Wash with "dirty/used" PGDA Wash Solvent
  3. Second Stage Cleaning: Run Wash cycle in Form Wash with fresh PGDA Wash Solvent. Due due to the prior wash cycles this PGDA can be used for an extended period of time. If performance deteriorates use in first stage.
  4. Final Stage: Remove any PGDA Wash Solvent with compressed air and rinse in n-Butly Acetate to speed up the evaporation of PGDA Wash Solvent.
