Use a resin made for the exact laboratory workflow

A dental model resin, a castable pattern resin, and a material intended for patient contact are different product categories. Their documentation and processing controls must remain separate.

Dental arches, working models, removable dies and castable patterns produced by resin 3D printing
Model production is a complete material workflow. Printer exposure, resin condition, part orientation, washing, drying, post-curing and inspection all contribute to the final model surface and repeatability.

Washable Dental Model Resin

A clear resin direction for dental model and transparent model workflows. The word “washable” must not be interpreted as permission to use water alone. Confirm the approved cleaning medium and process in the current TDS or IFU.

  • Published appearance: clear
  • Cleaning method requires document confirmation
  • Do not substitute an unapproved washing liquid
Green translucent dental castable pattern resin and detailed 3D printed casting patterns Castable Pattern Resin

Dental Castable Pattern Resin

A green translucent resin positioned for dental casting models and castable pattern workflows. Printing success does not by itself confirm casting performance. Burnout behavior, residue, investment compatibility and dimensional results require validation with the intended casting process.

  • Published appearance: green translucent
  • Positioned for patterns rather than direct restorations
  • Casting workflow testing remains necessary
Four selection controls

Do not select dental resin by color or price alone

Begin with the intended printed output and then confirm the complete equipment and post-processing chain. A material that prints successfully on one machine may require a different exposure profile or may not be supported on another system.

01

Intended output

Define whether the part is a working model, verification model, display model or castable pattern.

02

Printer matching

Confirm printer model, light source, resin profile, vat system and supported exposure range.

03

Inspection needs

Select color and opacity according to surface observation, scanning, photography and technician preference.

04

Post-processing

Verify the permitted cleaning medium, drying method, curing equipment, curing conditions and acceptance checks.

Printer and resin compatibility

Confirm the exact printer–resin combination

Public product descriptions provide an initial wavelength and printer-technology direction. Production approval still requires testing with the target printer, resin batch, model geometry and laboratory process.

  • Exact dental 3D printer model and light-source specification
  • Current resin SKU, batch and supported wavelength range
  • Approved layer thickness and exposure profile
  • Platform, vat and release-film condition
  • Cleaning and post-curing equipment compatibility
  • Representative sample print and documented inspection
Material comparison

Material category Published appearance Primary model workflow Cleaning position Documents to confirm
Gray dental model resin Gray Dental working models, verification models and related non-intraoral laboratory model production Follow the cleaning medium and procedure stated for the exact resin SKU TDS, SDS, printer compatibility information and post-curing instructions
Yellow dental model resin Yellow Dental arches, crown-and-bridge model workflows and laboratory model visualization Do not copy a cleaning process from another resin TDS, SDS, exposure profile, cleaning instructions and curing requirements
Washable dental model resin Clear Clear or transparent model workflows and model verification Confirm the permitted washing medium; do not assume water-only cleaning Current TDS, SDS and written cleaning instructions
Dental castable pattern resin Green translucent Dental casting models and castable pattern preparation Follow the resin instructions before investment and burnout TDS, SDS, casting-process guidance and internal burnout validation

This comparison is intended for initial material screening. It does not replace the controlled product documents supplied for the selected SKU.

Cleaning and UV post-curing

Keep the documented post-processing sequence unchanged

Cleaning removes uncured surface resin, while post-curing completes the specified material workflow. The correct washing medium, duration, curing wavelength, time, temperature and model orientation depend on the exact material and equipment system.

Step 1

Drain and handle

Remove the build carefully and allow excess resin to drain according to the documented procedure.

Step 2

Clean

Use only the washing medium, equipment and sequence authorized for the selected resin.

Step 3

Dry and inspect

Confirm that recesses and internal surfaces are clean and fully dry before post-curing.

Step 4

Post-cure

Use compatible UV equipment and the validated curing cycle for the exact resin and model.

Storage and safe handling

Treat uncured resin and contaminated cleaning liquid as controlled materials

Read the current SDS before opening a container. Workplace controls, personal protective equipment, spill response, storage conditions and disposal procedures must follow the resin documentation and applicable local requirements.

Wear the personal protective equipment specified in the SDS.
Avoid direct skin and eye contact with uncured resin.
Work in an appropriately ventilated resin-processing area.
Keep containers closed and protected from uncontrolled light.
Separate resin types, batches and contaminated tools.
Do not pour uncured resin or contaminated wash liquid into drains.
Application boundary

Separate dental model printing from direct intraoral use

Yidimu supplies 3D printing equipment and materials. It is not a hospital, dental clinic or treatment provider. Model-resin descriptions on this page do not establish suitability for patient-contact parts, diagnosis, treatment or clinical use.

Do not describe a resin as biocompatible unless the claim is supported by documentation for the exact product and intended use.
Do not infer FDA, CE, ISO, MDR or other regulatory status from a general product description or an unrelated material certificate.
Guide, temporary, denture or other patient-contact applications require matching intended-use documents, printer compatibility and validated post-processing instructions.
A qualified dental professional is responsible for confirming the final application under the applicable instructions and local regulations.
Application-specific resin requests

Submit the intended use before requesting a specialized dental material

For surgical-guide, temporary, denture, restoration or other patient-contact applications, provide the exact intended use, target market, printer model and required documentation. A material should only be proposed after its product scope, compatibility, processing instructions and regulatory information have been reviewed.

Frequently asked questions

Dental resin questions

Which resin should I use for printed dental models?

Select a model resin according to the required model color, surface observation, printer compatibility, dimensional requirements and post-processing workflow. Run a representative sample before approving repeated production.

Does “washable dental resin” always mean water-washable?

No. The product name alone does not define the permitted cleaning liquid. Confirm the current TDS or IFU before using water, alcohol or any other washing medium.

Can dental model resin be placed directly in the mouth?

A model resin must not be treated as an intraoral material unless the exact product has documented intended use, applicable regulatory status, biocompatibility evidence and a validated printing and post-processing workflow.

Are these resins compatible with every LCD or DLP printer?

No universal compatibility should be assumed. Confirm the printer model, wavelength, light intensity, resin profile, vat system and exposure settings before production.

Why are dental model resins available in different colors?

Color and opacity affect visual inspection, photography, scanning and the visibility of surface details. Color does not by itself establish accuracy, strength or suitability for a particular dental application.

How long should dental resin models be washed and UV cured?

There is no single time that applies to every resin. Use the instructions for the exact resin, model geometry, printer and curing unit. Do not copy washing or curing settings from another material.

What documents should a professional buyer request?

Request the current TDS, SDS, IFU when applicable, printer compatibility information, exposure guidance, cleaning instructions, UV post-curing requirements, storage conditions, shelf-life information and any application-specific regulatory documents.

What information should I send for resin matching?

Provide the printer model, model dimensions, intended output, required color, quantity, critical details, expected post-processing workflow, target market and any documentation required by your organization.

Request resin documentation and compatibility review

Send the printer model, dental model type, dimensions, resin color, expected quantity and post-processing requirements. Yidimu can review the available material direction and identify which technical documents still need confirmation.
