Understanding the Two Platforms

Although both printers create highly accurate dental parts, they were designed around different philosophies.

Asiga

Asiga has built its reputation around open-material compatibility. Users can select from hundreds of validated resins rather than being restricted to a single manufacturer's ecosystem.

This flexibility appeals to laboratories that frequently switch between restorative, orthodontic, implant, and surgical applications.

Common uses include:

Crown and bridge models
Surgical guides
Splints
Custom trays
Denture bases
Orthodontic models
Gingiva masks
Castable patterns

Because the platform is open, technicians can optimize material selection based on clinical performance, pricing, or availability.

At Repair.Dental, we often see laboratories choose Asiga specifically because they want freedom from proprietary resin limitations.

NextDent

NextDent has traditionally emphasized a validated workflow where hardware, software, and materials work together as an integrated ecosystem.

Rather than offering unlimited flexibility, the platform focuses on:

Predictable printing
Regulatory compliance
Consistent material performance
Simplified workflows
Clinical repeatability

For many dental practices that print the same applications every day, this consistency can be a major advantage.

Neither printer has a decisive quality advantage for everyday dentistry.

Instead, workflow preferences become the deciding factor.

Every calibration performed by Repair.Dental reinforces one important lesson: even premium printers only maintain their advertised accuracy when properly maintained and calibrated.

Material Flexibility

One of the biggest differences between these platforms is resin compatibility.

Asiga

The open-material approach provides tremendous flexibility.

Benefits include:

Hundreds of compatible resins
Lower operating costs
Greater supplier choice
Easy adoption of new materials
Reduced dependency on one vendor

For larger laboratories, this flexibility often translates into significant long-term savings.

NextDent
