The Complete Workflow

STEP 1

Print

Upload your model to PreForm and let the software automatically orient and generate supports. Then, load the material and start printing.

STEP 2

Wash

Load your part into the Form Wash L and walk away. Automated part cleaning ensures controlled solvent exposure — the most critical step in the post-processing process.

STEP 3

Cure

Post cure to solidify the material properties of your part. Your part is now ready for use.

Medical

"Since we're producing surgical-grade equipment, the biocompatibility of the resins is crucial. The ability for prints to start and finish correctly, along with the duration, can impact patient care if we're working against a deadline. With Form 4BL, we've achieved a 100% success rate on our parts."

Todd Goldstein | Northwell Health

Medical

"I'm blown away by how fast the Form 4BL prints. Using Fast Model Resin on the Form 4BL, we printed an anatomical model of a spine in just an hour and a half and delivered it the same day. Without that speed, we wouldn't have been able to respond to the case in time.

Form 4BL FAQs

What is the Form 4BL build size? What is the largest part I can print?

The Form 4BL has a build size of 13.9 x 7.7 x 13.8 inches. The printer allows you to print parts up to the max build size.

What is the size difference between Form 4B and Form 4BL?

The Form 4BL is a large-format medical printer for biocompatible, sterilizable parts. It’s build size is 4.6x larger than the Form 4B.

What types of materials can I print on the Form 4BL?

Formlabs has over 40 resins ranging from tough and durable, high temp, and flame retardant, rigid and flexible, to silicone and ceramic.

Material Examples:

Tough 2000: Similar to ABS
BioMed Amber: Biocompatible Resin
Silicone 40A: True Silicone
Grey: Most Accurate When Printed and Cured
BioMed White: Biocompatible Resin
BioMed Flex 80A: Biocompatible Resin

Is resin 3D printing strong?

It depends on the material, but resin prints can be surprisingly strong. One key advantage is that they’re isotropic, so strength is consistent in every direction.

Is there an Open Material Mode on Form 4BL?

Yes, Open Material Mode is available for a single lifetime fee per printer. Open Material Mode allows you to print with any third-party 405 nm photopolymer resin.

Can I upgrade a Form 4L to a Form 4BL?

There is no current upgrade path from the Formlabs Form 4L to the Formlabs Form 4BL. If you require biocompatible printing, a separate Form 4BL system is needed.

How can I dispose of unused and expired resin?

To dispose of unused or expired resin, consider using the WRAP Pro to print a solid form that can be safely discarded. Hazardous waste services can be cumbersome and expensive, and the WRAP allows you to deal with this hassle seamlessly.

What equipment is used for post-processing?

The Form Wash L and Form Cure L are part of the Form 4BL workflow. Form Wash L is the second step in the workflow. It automatically cleans printed parts thoroughly with IPA or alternative solvents to leave your parts pristine and ready to be cured. After the parts are clean, they are placed in Form Cure L to be post-cured and solidify mechanical properties.

What is PreForm?

PreForm is Formlabs’ easy to use software included with your printer purchase. PreForm is offered for free, with no licenses, annual fees, or installation limits. PreForm’s automatic algorithms set up your print’s layout, orientation, and supports.

Features Include:

Supports
Add Textures
Remote printing
Automatic support generation
Optimal orientation recommendations
Real-time print estimates
Print settings tuned and validated for Formlabs’ entire materials library
Automatic detection for common issues (gaps, ensuring your models are print-ready)
Customize all settings

What is the purpose of the camera on the Form 4BL?

If the integrated camera is enabled, it automatically saves a photo of each print when it completes. The camera also allows users to take video timelapses of the printing process and snapshots of the build platform from Dashboard.

Can I use Form 4BL offline?

Formlabs printers can operate entirely offline to meet security requirements by using direct USB connections or local area networks (LAN) without internet access. Users can transfer jobs via PreForm, while firmware updates and Open Material Mode activation still require temporary connectivity.
