What Is Formlabs Post-Processing?
Every Formlabs 3D print requires post-processing to achieve its final material properties, surface quality, and dimensional accuracy. For SLA resin printers, that means washing away uncured resin and UV curing the part to complete the chemical reaction started during printing. For SLS powder printers, it means recovering parts from the powder bed and finishing the surface for functional use. Formlabs offers a purpose-built post-processing system for each printer so you can build the right workflow from print to finished part.

Form Wash + Form Cure
The Form Wash and Form Cure completes the post-processing workflow for the Form 4 and Form 4B. After printing, parts are automatically washed to remove excess resin before being UV cured to achieve their final material properties. Together, these systems help streamline the workflow from printed part to production-ready component.
Form Wash
The Form Wash automatically removes uncured resin from printed parts before curing. It accommodates build platforms from the Form 2, Form 3/3B, and Form 4/4B printers, allowing you to transfer parts directly from the printer into the wash. By automating the washing process, it helps deliver consistent results while minimizing manual handling.

Form Wash L + Form Cure L V2
The Form Wash L and Form Cure L V2 are designed for the larger build volume of the Form 4L and Form 4BL. They provide the same automated washing and curing workflow as the desktop systems while accommodating larger parts and higher production volumes. Together, they help move large-format resin parts from the printer to finished components with minimal manual handling.
For use with: Form 4L | Form 4BL
Form Wash L
The Form Wash L is the large-format washing solution for Formlabs SLA printers. It accommodates build platforms from the Form 2, Form 3/3B, Form 4/4B, and Form 4L/4BL printers, including larger parts and full build platforms. Using the same slotted mounting system as the Form Wash, it automates the washing process to deliver consistent results while supporting high-volume resin printing workflows.

Frequently Asked Questions (FAQs) About Formlabs Post-Processing
What post-processing system do I need for my Formlabs printer?
The Form 4 and Form 4B pair with the Form Wash and Form Cure, while the Form 4L and Form 4BL require the larger Form Wash L and Form Cure L V2. The Fuse 1+ 30W uses the Fuse Sift for powder recovery and the Fuse Blast for surface finishing. Each system is designed to work directly with its paired printer, accepting the build platform or build chamber without any additional adapters.
