The Complete Guide to Dental 3D Printing Resins

Walk into any digital dental lab today and the story is the same. The printer gets the attention, but the resin is what actually determines whether a case succeeds. Fit, shade match, biocompatibility, how a part behaves during cementation or delivery: all of it comes down to choosing the right photopolymer for the job.

The problem is that “dental resin” isn’t one product. It’s more than a dozen distinct categories, each engineered for a different clinical purpose, and naming conventions differ by manufacturer. This guide breaks the entire category down so you always know exactly what you’re ordering and why.

What Is DLP Resin Printing?

Every resin in this guide is formulated for DLP (Digital Light Processing), the print technology behind Asiga’s dental printers and the standard the dental industry has converged on for chairside and in-lab production. Instead of tracing each layer with a single laser point the way SLA does, a DLP printer flashes an entire cross-section of the model at once, using a digital micromirror device to cure the full layer in one exposure.

For a dental lab, that difference matters in three practical ways:

  • Speed at volume.
    Because DLP cures a whole layer per flash instead of point-by-point, print time depends on the height of a job, not how many parts are packed onto the tray. That’s why labs can nest a full arch of crowns or a plate of guides in a single run without a meaningful time penalty.
  • Consistent accuracy across the build.
    Every point in a layer is exposed for the same duration, which reduces the layer-to-layer variability that can show up in laser-based systems, especially over a large build volume.
  • Resin chemistry built around light, not lasers.
    DLP resins are formulated for a specific wavelength and light engine. That’s why cure profiles are matched to both a resin and a printer model. A resin engineered for one DLP light engine won’t necessarily perform correctly on another without a validated profile.

Every resin category below (model, guide, appliance, denture, temporary, permanent) is a DLP resin formulated to run on Asiga’s dental printer line.

Why Resin Choice Actually Matters

Every DLP resin trades off the same three variables: accuracy, mechanical strength, and biocompatibility. A model resin is optimized for dimensional stability on a dry lab bench, not for sitting in a patient’s mouth. A surgical guide resin is certified biocompatible but isn’t built to hold the fine detail of a preparation margin. Picking the wrong category doesn’t just cost you a reprint. It can cost you a clinical outcome.

Below, we walk through every resin category we carry, from Asiga, TopCore, Detax, Dentona, Bego, and Saremco, organized the way a lab actually thinks about a case: model, guide, appliance, denture, temporary, permanent.

1. Model & Study Resins

The workhorse of any lab. These resins print dimensionally stable, ivory or tan-shaded models that hold up to trimming, articulation, and repeated handling.

  • Asiga DentaMODEL: the industry benchmark for accuracy and layer adhesion.
  • TopCore Model PRO: our house brand, and a genuine alternative to DentaMODEL rather than a compromise. Same dimensional accuracy class, same handling on the build platform, comparable price. If you’re evaluating a second model resin to dual-source against supply issues, start here.
  • TopCore Model ECO: the most cost-efficient model resin in our catalog, roughly half the per-bottle cost of DentaMODEL. A solid default for high-volume diagnostic models where every dollar of consumable cost matters.
  • Detax FREEPRINT Model 2.0: a premium option favored for crisp margin definition.
  • Dentona Optiprint Model: a golden-brown shade engineered to process like classic plaster models, with strong abrasion resistance.
  • Asiga DentaSTUDY and Dentona Optiprint Match: purpose-built for orthodontic study models.
  • FunToDo Dentifix-3D Modelling HR: a high-resolution option when fine anatomical detail is the priority.

2. Try-In & Diagnostic Resins

Asiga DentaTRY is engineered specifically for prototypes and try-ins with thin, removable sections, a job standard model resin isn’t built to survive.

3. Surgical Guide Resins

Biocompatible and rigid, these resins hold the tight tolerances implant placement demands.

4. Custom Tray Resins

5. Splints, Night Guards & Orthodontic Resins

This category covers occlusal splints, night guards, retainers, and orthodontic appliance components, all of which need to survive months of intraoral wear.

6. Bite Registration (IBT) Resins

7. Denture Bases, Teeth & Gingiva Resins

Full and partial denture workflows typically combine a base resin, a tooth-shade resin, and a gingiva or soft-tissue resin.

8. Casting & Burnout (Wax Pattern) Resins

For labs still casting frameworks in metal, these resins burn out clean with a standard wax burnout schedule.

9. Temporary Crown & Bridge Resins

10. Permanent Crown & Restoration Resins

This is the newest and highest-stakes category in dental 3D printing: materials rated for long-term intraoral function, not just temporaries.

  • Bego VarseoSmile Crown plus: a tooth-colored, ceramic-filled hybrid material, and currently the
    only resin in our catalog rated for permanent single crowns, inlays, onlays, and veneers.
    If your lab is exploring permanent restorations printed rather than milled, this is where to start.
  • Saremco Crowntec: premium permanent restoration resin.
  • Detax FREEPRINT Crown: the highest price point in the category, positioned for high-end permanent casework.

Choosing Between Brands: A Quick Framework

With five manufacturers and a dozen categories, the decision usually comes down to three questions:

  1. Is this resin going in a patient’s mouth long-term, or staying on the bench?
    Bench materials (models, trays, casting patterns) have more room to shop on price. Anything intraoral for more than a few days should stay within a manufacturer’s clinically validated line.
  2. Do you print a high volume of one category?
    If models are your single biggest resin spend,
    TopCore Model PRO and Model ECO
    are worth qualifying as your default. They hold the accuracy labs expect from Asiga DentaMODEL at a lower cost per case, and stocking a second qualified brand also protects you against single-supplier backorders.
  3. What’s already validated on your printer’s exposure library?
    Asiga’s open-material system supports all the brands in this guide, but always confirm the correct cure profile before running a new resin in production.

FAQ

What’s the difference between DLP and SLA resin?
Dental resins are largely formulated for one technology or the other, depending on the printer’s light engine. All resins in this guide are formulated for Asiga’s DLP printers.

Are these resins biocompatible?
Categories used intraorally (guides, splints, temporaries, permanent restorations, trays) are certified biocompatible per their manufacturer, with CE Class I/IIa ratings where applicable. Bench-only resins (models, casting patterns) are not intended for intraoral use.

How long does an opened bottle of resin last?
This varies by resin chemistry and storage conditions. Check the technical data sheet for your specific product, and store resin away from UV light and heat.
