Form Wash System Overview

Form Wash automatically cleans uncured liquid resin from 3D printed parts’ surfaces.

  1. Platform Mount. Holds the build platform when washing parts on the platform.
  2. Basket. Holds parts to wash without the build platform.
  3. Basket Mount. A single hook secures the basket to raise and lower.
  4. Outer Lid. Limits IPA evaporation. Keep the lid closed when not in use.
  5. Inner Lid. A hinged, secondary lid opens and closes to contain IPA while allowing parts to be lowered or raised from the bucket.
  6. Wash Bucket. Removable container holds a maximum of 8.6 L of IPA. A rotating impeller at the bottom circulates IPA.
  7. Display. Shows status, time, and options for configuring Form Wash.
  8. Knob. Turn or push to adjust time and to start, pause, or end a wash cycle.
  9. Tool Storage. Each side has designated locations for storing each tool.
  10. Power Supply. Provides power to Form Wash. Specifications: 24 V, 2 A
  11. Isopropyl Alcohol (IPA). Not included. Dissolves liquid resin from printed parts’ surfaces. Start with 10 L. Concentration must be 90% or higher.
Additional Supplies
  • Isopropyl alcohol (IPA), 90% or higher
  • Powder-free, chemical-resistant, disposable gloves
  • Paper towels

Tools & Storage

Form Wash includes storage space for commonly used tools during the part cleaning process.

  1. Flush Cutters. Use to carefully remove support tips from printed parts.
  2. Removal Tool. Apply pressure under the base generated by PreForm to release the base of your parts from the build platform.
  3. Hydrometer. Float in IPA to measure the IPA’s resin concentration, based on previous calibration in fresh IPA.
  4. Scraper. Can be used to remove parts from the build platform, as well as to carefully clean and inspect the resin tank for cured material.
  5. Tweezers. Use to handle small parts or to manipulate supports after printing.
  6. Siphon Pump. Transfer IPA between the wash bucket and an IPA storage container.


Practice safety when using Formlabs products, including Form Wash. These resources may be helpful:

  • Safety Data Sheets (SDS) for Formlabs Materials
  • Considerations when using Isopropyl Alcohol (IPA)


As more parts are cleaned, the IPA gradually becomes more concentrated with liquid resin, reducing the effectiveness of Form Wash. The hydrometer indicates when the IPA’s resin concentration has reached 10-12%, however parts may feel slightly tacky at 5-10% concentration. As IPA evaporates, add fresh IPA to keep the fill level between the minimum and maximum lines. Use the hydrometer to check the IPA’s resin concentration between cleaning cycles, and replace IPA as needed for the cleanest parts.

Basic Care

Clean the hand-held tools with fresh IPA, then store them in the rear storage on the right and left sides of the Form Wash.

Use separate wash baskets and wash buckets to preserve part color and quality. Spare Wash buckets will be available to purchase soon through the Formlabs store. Maintain separate equipment to meet biocompatibility requirements for some resins, such as Dental SG Resin.
