Blender for Dental (B4D)

Blender for Dental (B4D) is a commercial set of dental CAD modules that runs inside Blender, the free open-source 3D suite. It is aimed at dental technicians and labs that want to design crowns, splints, trays, bars and surgical guides without a traditional closed CAD system. When people search for “blender for dental”, this is usually the product they mean: a user interface that launches Blender with dental menus, plus modules you buy one by one.

It is important to separate the two parts. Blender itself is free and open source under the GNU GPL, maintained by the Blender Foundation. The B4D modules are paid and sold by Blenderfordental, so B4D is shareware (conditionally free): Blender and the B4D interface installer are free to download, but the dental tools need purchased modules. B4D is an independent project and is not affiliated with the Blender Foundation.

Blender for Dental at a glance

What it does

• Adds dental menus to Blender through modules such as Model Designer, Crown & Bridge, Denture Designer, Splint & Layers, Tray Designer, Guide Designer, WaxUp, BlockOut, Gum Designer and Bleaching Trays.
• Model Designer, the prerequisite module, turns scanned arches into printable models with bases.
• Implant-related modules (All-On-X Hybrids, Implant Bars, iBar, iAbutment & Bar) cover bar and hybrid restoration design.
• Articulator & Facebow and ICP Alignment modules help mount and align scans.
• Guide Designer handles surgical guide design and DICOM-based implant planning, according to the vendor.
• Exports STL for 3D printing and milling, and keeps Blender’s own mesh tools available for sculpting, Booleans and remeshing.
• Tooth libraries and articulator models are sold as add-on content in the B4D shop.

How dental teams use it

Printable model from an intraoral scan

1. Export the arch from your intraoral scanner as STL or PLY.
2. Launch Blender through the B4D User Interface and open Model Designer.
3. Import the scan, trim it, set the occlusal plane and add a base.
4. Hollow the model if your printer workflow calls for it, then export STL to the slicer.

Occlusal splint

1. Import upper and lower scans and align the bite (ICP Alignment if needed).
2. Block out undercuts, then build the splint shell with Splint & Layers.
3. Adjust thickness and occlusal contacts, then export STL for printing.

Crown and bridge design

1. Load the prepared scan and mark margins in the Crown & Bridge module.
2. Place teeth from a library and adapt shape and contacts.
3. Export the restoration for milling or printing.

Install and first run

• Windows: Windows 8.1 64-bit or newer. The vendor’s minimum is a quad-core CPU, 8 GB RAM and a graphics card with 2 GB VRAM; an 8-core CPU, 32 GB RAM and 8 GB VRAM are recommended.
• macOS: macOS 11.2 or newer with 8 GB RAM; macOS 14 on Apple silicon with 32 GB RAM is recommended.
• Install the B4D User Interface, log in with your blenderfordental.com account, install Model Designer first, then the modules you have bought. The interface launches Blender with the B4D menus loaded.
• B4D modules currently target Blender 4.5 LTS, and new scripts are not compatible with older Blender versions. A newer Blender 5.x from blender.org is not the version B4D expects, so start your dental work from the B4D interface rather than from a separate Blender install.
• A licence can be installed on three stand-alone computers. A fast, stable internet connection is needed for installation and updates.
• If you are moving from the older Blender 3.6 LTS setup, finish open cases first: the vendor warns that 3.6 project files may not be fully compatible with 4.5.

Limitations

• The dental modules are paid; Blender alone does not include dental tools.
• No Linux version of the B4D interface.
• Learning curve: you work inside Blender’s general-purpose interface, which takes time for users coming from dental-only CAD.
• The vendor states that CAD work done with B4D is at the user’s own risk. B4D says it is listed as a Class I medical device in the EU; it makes no FDA claim on its site.
• The vendor does not offer refunds on software purchases, so review module descriptions and tutorials before buying.

Blender for Dental vs alternatives

B4D vs exocad: exocad is a full commercial dental CAD platform with broad scanner and milling integrations; B4D is modular, cheaper to start with and built on an open 3D tool, but relies more on the user’s own skill. Around any dental CAD, MeshLab is a free way to repair and decimate scans, and Blue Sky Plan is a common choice for implant planning and guides. FreeCAD suits mechanical parts rather than organic tooth shapes. Free, open-source Blender add-ons also exist, for example BDENTAL by Issam Dakir for CBCT viewing and implant planning, and OrtogOnBlender by Cicero Moraes for orthognathic surgery planning.

FAQ

Is Blender for Dental free?

No. Blender is free and open source, and the B4D interface installer costs nothing to download, but the dental modules are paid. That makes B4D shareware (conditionally free), not freeware.

Is there a Blender for Dental free trial?

The official site does not describe a trial. It offers free digital samples and tutorial videos; the modules themselves are purchased individually.

How does Blender for Dental pricing work?

Modules are bought one at a time and owned without annual licence fees, and module updates are free. Model Designer is required before other modules. Check the official shop for current terms.

Blender for Dental vs exocad: which should I choose?

Choose exocad if you need a mainstream, fully supported lab CAD with wide scanner and milling integration. B4D fits technicians who are comfortable in Blender and want a modular, lower-entry setup.

How do I install Blender for Dental?

Install the B4D User Interface for Windows or Mac, log in with your account, install Model Designer, then add your modules. The interface starts Blender 4.5 LTS with the dental menus.

Does Blender for Dental run on Windows 10?

Yes. The vendor lists Windows 8.1 64-bit as the minimum, so Windows 10 and 11 are covered.

Where can I find a Blender for Dental tutorial or course?

Each module comes with tutorial videos, and the official site lists accredited tutors, events and a certification programme.

How do I make teeth in Blender without B4D?

You can sculpt teeth or import a tooth-library mesh in plain Blender, but you will not get margin, insertion-axis or thickness tools. For clinical work, use dedicated dental modules or dental CAD.
