exocad vs 3Shape vs Blender for Dental: which CAD to learn
exocad vs 3Shape vs Blender for Dental compared by a certified trainer: licensing, openness, learning curve and which dental CAD fits a lab or freelancer.
Technicians starting digital work and lab owners choosing where to invest ask me the same question: which dental CAD should they learn or buy. No single program suits everyone. The right choice depends on the scanners the clinics use, the indications the lab produces and how the person designing likes to work. This comparison of exocad vs 3Shape vs Blender for Dental covers those three factors.
My own position first. I am an exocad Certified Trainer and a Blender for Dental Accredited Instructor. I handle 3Shape files every day but I do not teach 3Shape, so the 3Shape section is a user’s view.
The three platforms at a glance
| exocad DentalCAD | 3Shape Dental System | Blender for Dental | |
|---|---|---|---|
| Approach | Open and modular, sold through resellers and OEM partners | Integrated ecosystem around 3Shape scanners and services | Dental add-ons on free, open-source Blender |
| Workflow | Guided wizard, very fast on standard indications | Guided workflows, tight integration with TRIOS and 3Shape tools | Free modeling with dental tools and full control |
| Licensing | Perpetual or Flex subscription | License and service plans from 3Shape and partners | Modules bought individually, no yearly fees according to the developer |
| Learning curve | Low to medium | Low to medium | Medium to high |
| Strongest for | Daily lab production, implants, wide range of indications | Labs working mainly with TRIOS clinics | Free-form design, bars, custom solutions, limited budgets |
exocad DentalCAD
exocad is the most widespread open CAD in dental labs. It imports standard mesh formats and integrates with a long list of scanners, implant libraries and CAM systems. It is sold through a reseller network, including OEM versions branded by other manufacturers.
Its wizard makes standard indications fast and repeatable: crowns, bridges, inlays, abutments and bars. The software is modular, so implant, virtual articulator, smile design, model creator or denture modules are added when the lab needs them. The implant library ecosystem is very large, and exports include metadata for CAM (see the .constructionInfo file).
The limits show on free-form work outside the wizard, which is possible but less flexible than in a true 3D modeler. Costs grow with each module, so the license model matters (see perpetual vs Flex).
exocad fits labs and milling centers that want predictable daily production and freedom in choosing scanners and manufacturing partners.
3Shape Dental System
3Shape builds intraoral scanners, lab software and cloud services designed to work together. Dental System is the lab CAD in that ecosystem, with guided workflows for the main indications and tight integration with TRIOS scans and 3Shape communication tools.
When both the clinic and the lab work in 3Shape, the path from TRIOS scan to lab design is very smooth, and the range of 3Shape applications around it is broad. The advantage shrinks in labs that receive scans from many different systems. License and service terms depend on 3Shape and its partners, and they deserve a careful comparison.
3Shape fits labs whose main clinics send TRIOS cases and who prefer a single integrated vendor.
Blender for Dental
Blender for Dental (B4D) adds dental modules to Blender, the free open-source 3D suite. You get tools for crowns and bridges, bars, models, guides and more, on top of a complete 3D modeler.
The strength is modeling freedom: sculpting, boolean operations, mesh repairs and shapes no wizard offers. The total cost is low, since Blender is free and modules are bought one at a time. It handles bars and complex implant work very well, for example with iBar (see designing Toronto bridges with iBar), and it has constant development and an active community.
The learning curve is steeper, especially for technicians who have never used 3D software, and routine indications take more steps than in a wizard-based CAD. The extra freedom also leaves more room for mistakes, so it rewards a disciplined way of working.
Blender for Dental fits technicians who enjoy 3D modeling, freelancers and small labs watching costs, and it works well as a second tool next to exocad or 3Shape.
Other dental software you will meet
Dentbird is a browser-based tool that generates crowns with AI. It is useful for simple single units and does not replace a full lab CAD (see my review). Blue Sky Plan offers free implant planning and guide design with pay-per-export (see the guide). Meshmixer is still used for mesh edits, but it is no longer developed (see what replaces it). Dental Wings, a long-established lab CAD, is now part of the Straumann group.
How to choose a dental CAD
- Look at what arrives: which scanners your clinics use and which formats they send.
- Look at what leaves: which milling centers and printers you work with, and what files they need.
- List your indications. Mostly crowns and bridges favors a wizard-based CAD. Many bars and custom shapes favor adding Blender for Dental.
- Count the learning time. Software that nobody in the lab masters is expensive whatever its price.
- Try it on your own cases, with a trial or a guided session, before you buy.
The software multiplies the knowledge of the person using it. Anatomy, occlusion and material limits are the same in every CAD, which is why training on real cases matters more than the choice of platform.
Frequently asked questions
Which dental CAD software is best for beginners?
exocad is usually the easiest start for crown and bridge work thanks to its guided wizard. Blender for Dental is very capable but asks for more 3D modeling habits. 3Shape is a natural choice if the lab already works in the 3Shape ecosystem.
Is Blender for Dental free?
Blender itself is free and open source. The Blender for Dental modules are paid, bought individually and, according to the developer, without yearly license fees.
Can I use exocad with any intraoral scanner?
exocad is open software that imports formats such as STL, PLY and OBJ, and many scanner makers integrate with it directly. Check the export options and integration of the specific scanner.
Should a lab run more than one CAD software?
Often yes. A common setup is exocad or 3Shape for daily production and Blender for Dental for free-form work, repairs and special cases.
