Sun Beam 3D+ Mestra: professional UV post-curing unit for dental 3D printing
The Sun Beam 3D+ Mestra is a professional UV post-curing unit designed to complete the curing of resin-printed parts. It secures the most critical stage of the digital workflow: post-processing.
Result: dental models and 3D printed dental appliances that are stronger, dimensionally stable, and more reliable during finishing, try-in, and clinical use.
Why is it essential? Right after printing, resin is only partially cured. Final post-curing is required to achieve the hardness, stability, and safety expected in a professional dental laboratory.
improved flexural resistance and wear performance.
better dimensional stabilization of printed parts.
reduced tackiness for a cleaner, more professional finish.
helps follow resin manufacturer post-curing protocols.
Why post-processing matters for 3D printed dental models and appliances
In dental 3D printing, print accuracy alone is not enough. Without controlled post-processing, a part may look correct but remain mechanically unstable or change over time. Final UV post-curing completes the resin’s polymerization reaction and secures the performance of the finished device.
- Mechanical properties: surface hardness, strength, durability.
- Dimensional stability: accuracy and fit.
- Hygiene and safety: fewer uncured resin residues on the surface.
- Finish: more consistent surface and easier polishing.
Recommended post-processing protocol (wash + dry + post-cure)
Remove uncured resin using isopropyl alcohol (often referred to as IPA). Effective washing reduces surface residues and improves the quality of the final cure.
Lab tip: follow your resin manufacturer’s recommendations (times, method, and bath renewal).
Ensure the part is fully dry. Proper drying prevents curing inhibition and helps achieve even exposure during post-curing.
Place the part in the Sun Beam 3D+ to complete polymerization. The 400–405 nm LED range matches the standard used by most modern dental resins.
Goal: final properties—strength, stability, clean surface, and a professional finish.
Applications in the dental laboratory
The Sun Beam 3D+ supports post-processing for photopolymer dental resins used in additive manufacturing workflows:
- Study models and working models.
- Surgical guides and planning devices.
- Orthodontic aligner workflows (models for thermoforming).
- Temporary restorations, try-in parts, and validation pieces.
- Castable resins (investment and casting workflow) according to manufacturer protocol.
- Denture bases and prosthetic components depending on resin indication.

Investing in controlled post-curing: immediate benefits for the dental lab
A reliable post-curing unit is not an accessory—it is a quality tool that secures every print. By controlling post-processing, you increase productivity and reduce risks (fragile parts, adjustments, remakes, and long-term instability).
In practice: uniform post-curing supports repeatable results and helps meet resin manufacturer protocols—especially important for devices intended for clinical use.

Frequently asked questions
Why is final post-curing essential in dental 3D printing?
Because a printed part is only partially cured when it comes off the printer.
Post-processing completes polymerization and improves mechanical strength.
It stabilizes dimensions and leaves a cleaner surface.
This is the step that turns a “raw” print into a reliable dental laboratory device.
Is the Sun Beam 3D+ suitable for common dental resins?
Yes, its 400–405 nm LED range matches the wavelength used by many dental photopolymer resins.
It is suitable for models, surgical guides, temporaries, and castable resins according to manufacturer protocols.
How does proper post-processing affect accuracy and fit?
It limits micro-deformation and stabilizes geometry.
This supports more reliable fit, especially for surgical guides and orthodontic workflows.
Parts maintain dimensional accuracy more consistently over time.
What is the maximum part size the unit can process?
The usable chamber size is Ø 260 mm × 140 mm (height).
It fits a wide range of printed parts.
Multiple items can also be post-cured at the same time depending on their footprint.
