Formlabs Form 4B 3D printer

Description

Form 4B is Formlabs' fast dental 3D printer for clinics and laboratories that want high production capacity, a broad material portfolio and a validated digital workflow. Low Force Display™ technology combines a high-resolution display, uniform LED illumination and a flexible resin tank to reduce separation forces and enable fast, repeatable printing across the build area.

Advantages

• Most prints can be completed in under two hours, with maximum print speeds up to 100 mm/h.
• 50 µm XY resolution provides fine details, sharp edges and smooth surfaces for dental models and appliances.
• Automatic resin identification, level sensing, dispensing and mixing reduce manual handling.
• A Z-axis force sensor adapts the process to geometry and material for stable print quality.
• Formlabs reports 98.7% print reliability in independent third-party testing.
• Open Material Mode enables compatible third-party resins in addition to Formlabs' dental material library.

Dental applications

• Diagnostic and orthodontic models
• Restorative models with removable dies and implant analogues
• Surgical guides
• Occlusal splints and retainers
• Temporary and permanent restorations depending on selected resin
• Denture bases, denture teeth and complete denture workflows
• Indirect bonding trays and other orthodontic applications

Workflow and software

PreForm Dental is used for orientation, support generation, material selection and print preparation. Dashboard enables remote monitoring, print history and fleet management. The integrated camera supports remote monitoring and timelapses and can be disabled or covered when required.

Materials

Formlabs currently lists support for 38 Formlabs materials on Form 4B, including 15 biocompatible materials, as well as third-party materials through Open Material Mode. The library covers applications such as models, surgical guides, splints, dentures and restorative indications.
