Formlabs Form 4BL

Medical & Dental Large-Format MSLA 3D Printer 

Form 4BL Overview

Formlabs Form 4L and 4BL Product Image

The Formlabs Form 4BL is a large-format MSLA resin 3D printer designed for high-volume dental, medical, and healthcare production that is too large for the Form 4B. Powered by Formlabs’ Low Force Display (LFD) print engine, the Form 4BL combines a large build volume with high-speed printing and compatibility with dental, BioMed, general purpose, and engineering materials. It enables laboratories and healthcare organizations to produce more patient-specific parts, models, and appliances in a single build.

Form 4BL Use Cases

High-Volume Dental Models

Print large batches of full-arch and quadrant models in a single build for aligners, restorative workflows, and high-volume dental production.

Surgical Guides

Create large surgical guides, orthopedic guides, and other patient-specific devices using validated biocompatible materials.

Large Anatomical Models

Produce full-scale anatomical models for surgical planning, medical education, and patient communication without splitting large parts across multiple builds.

Batch Medical Production

Print multiple surgical guides, dental appliances, anatomical models, and other patient-specific parts in a single build to increase throughput for busy labs and healthcare organizations.

Form 4BL Features and Benefits

The Form 4BL combines a 24.2-liter build volume with Formlabs’ portfolio of validated biocompatible materials, allowing larger parts and higher production volumes than desktop healthcare printers. 

The Low Force Display (LFD) print engine helps produce large biocompatible parts and full build platforms with consistent speed, accuracy, and surface quality. 

The Form 4BL supports Formlabs’ portfolio of Dental and BioMed materials for dental models, surgical guides, restorations, anatomical models, and other healthcare applications. The Form 4BL can also use General Purpose and Engineering resins for non-biocompatible applications. 

The Form 4BL is designed for healthcare professionals with validated materials, print settings, and workflows developed for dental and medical applications. Formlabs also provides material-specific manufacturing guides with information on processing, handling, and applicable sterilization requirements. 

When using biocompatible materials, users must maintain separate consumables, including dedicated build platforms, wash equipment, and tools, to help maintain biocompatibility. Formlabs provides material-specific manufacturing guides with requirements for consumables, processing, and sterilization.

orientation, support generation, print setup, and printer management. PreForm includes material-specific print settings and automated preparation tools to help streamline the path from CAD model to printed part. 

The Form 4B and Form 4BL are backed by Formlabs Medical Service Plans, which provide priority support, preventative maintenance, and service options designed for healthcare environments. 

Form 4BL Compatible Materials

The Form 4BL is compatible with Formlabs’ portfolio of Dental, BioMed, General Purpose, and Engineering materials, designed for patient-specific devices, anatomical models, surgical planning, prototyping, and other healthcare and manufacturing applications.  

Form 4BL Post-Processing Workflow

The Form 4BL integrates with Form Wash L and Form Cure L systems to streamline resin post-processing. Washing and curing help achieve the final material properties, surface finish, and dimensional performance required for production-ready parts. 

Frequently Asked Questions (FAQs) About Formlabs Form 4BL

The Formlabs Form 4BL is a large-format MSLA resin 3D printer built for medical and dental production. It combines the biocompatible material compatibility of the Form 4B with the expanded build volume of the Form 4L. This makes it well suited for high-volume healthcare workflows requiring larger parts or increased throughput. 

The Formlabs Form 4BL is the large-format version of the Form 4B designed for larger medical and dental applications. Its expanded build volume accommodates larger anatomical models, surgical guides, and patient-specific devices. This can reduce the need to split models across multiple builds or assemble printed sections. 

The Formlabs Form 4BL is a large-format MSLA resin 3D printer designed for medical and dental applications. It supports Formlabs’ portfolio of validated biocompatible materials while providing a larger build volume than desktop healthcare systems. This allows teams to produce larger patient-specific parts and more parts per build. 

The Formlabs Form 4BL is designed for high-volume dental production using validated biocompatible materials. Its larger build area allows more models, guides, and appliances to be produced in a single print job. This can help increase throughput while simplifying production planning and scheduling. 

The Formlabs Form 4BL is a large-format healthcare printer designed to consolidate production into fewer print jobs. Its expanded build volume enables larger batches and higher throughput from a single system. This can help reduce printer management overhead while supporting growing production demands.
