Form 4B Use Cases

Dental Models

Produce accurate dental and orthodontic models for restorative planning, treatment planning, aligner and retainer workflows, and patient communication.

Surgical Guides

Produce surgical guides and drilling templates using validated biocompatible materials designed for dental and medical applications.

Dental Appliances

Manufacture splints, denture components, temporary restorations, and other patient-specific dental appliances in-house using compatible dental materials.

Medical Applications

Create anatomical models, patient-specific devices, and medical prototypes using Formlabs’ portfolio of biocompatible materials.

Form 4B Features and Benefits

The Form 4B supports Formlabs’ portfolio of biocompatible BioMed materials for dental, medical, and healthcare applications.     From surgical guides to temporary restorations, you can choose materials designed for a wide range of patient-specific workflows. The Form 4B can also use General Purpose and Engineering resins for non-biocompatible applications. 

The Low Force Display (LFD) print engine helps produce dental and medical parts quickly without compromising accuracy or surface quality. Faster print times can help reduce turnaround times for patients and clinicians. 

The Form 4B is built for healthcare professionals with validated materials, print settings, and workflows developed specifically for dental and medical applications. Formlabs also provides material-specific manufacturing and sterilization guides for applicable BioMed materials. 

Formlabs’ BioMed and Medical Device Resins are manufactured in an FDA-registered facility within an ISO 13485-certified quality system and ISO Class 8 clean room environment. 

 

Explore Formlabs Biocompatibility & Certifications

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. 

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.  

The Form 4B works with PreForm, Formlabs’ print preparation software for part orientation, support generation, print setup, and printer management. Automated print preparation and material-specific settings help simplify the path from scan or CAD file to finished part. 

Form 4B Compatible Materials

The Form 4B 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 4B Post-Processing Workflow

The Form 4B integrates with the Form Wash and Form Cure systems for 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 4B
