DMD-31

Non-brittle 3D resin for dental models
32.00399.00 excl. VAT

Also available at our resellers

AmeraLabs dental model resin DMD-31 was developed with the help of experienced dental technicians. Designed to be the most accurate with minimum shrinkage. Additional additives make it non-brittle and dimensionally stable for challenging applications and smooth fitting of implant and dies. Pigmented to attractive beige (A2) and light grey colors for customer-facing cases.

Primary applications:

– implant supported and tooth borne fixed restoration models
– digital wax-up printing with excellent quality of surface and attractive color
– accurate removable dies and base of alveolar model (Willi Geller model)
– orthodontic models
– study models

Key Features

Used by

Designed for DLP 3D printers

Designed to perform best on professional DLP 3D printers equipped with 385nm – 405nm UV light (e.g. Asiga UV MAX).

Also compatible with monochrome LCD 3D printers (e.g. Phrozen Sonic Mini 8K, Elegoo Mars 3, Anycubic Photon Mono X 6k, Epax DX Pro). 

We have recommended 3D printing settings for many 3D printers here: AmeraLabs resin settings

DMD-31 DLP dental model resin produces dimensionally accurate and stable prints. That makes it perfect for various dental applications. Due to its stiffness and a fair amount of hardness it can sustain straight edges, produce accurate implant models and print out even the most complicated features. Supports do not bend during printing, keeping the model in place throughout the whole printing session and giving a higher rate of success with complex prints. Also it exhibits low shrinkage of less than 0.9% so the print will not deform during post-curing stage and will not crack over a long period of time.

Material is available in beige (A2) and grey colors. Carefully pigmented to get ideal color that expresses the most intricate details. Color is almost fully opaque. Surface is glossy and hard (90 Shore D). After post-cure it does not feel sticky or tacky and is pleasant to touch.

Post-curing slightly changes the color of 3D printed models. Longer post-curing will make models a bit more yellow. If you want to keep the original color, post cure for 5-10 minutes only.

Beige LAB color values:

  • before post-curing: L = 76, a = 2.2, b = 14
  • after 30 min. post-curing: L = 76, a = 2.6, b = 13.5

Grey LAB color values:

  • before post-curing: L = 76, a = -2, b = 0
  • after 30 min. post-curing: L = 74, a = -1, b = 2.8

Water absorption is around 0.2%. This means, that your models will not deform due to moisture or exposure to IPA.

For a successful print, we recommend:

Viscosity of this material is relatively low – around 400cps at 25°C – so cleaning is quite easy.
If you do not have ultrasonic cleaner or prefer cleaning with ordinary IPA baths, here is our easy 4 steps cleaning procedure:

  1. After taking your printed object off the build plate leave it submerged in the IPA bath for 2 minutes.
  2. Swirl the IPA bath with printed part in it actively for another 2 minutes.
  3. After swirling, leave it still, but fully submerged for another 2 minutes.
  4. Finally, swirl the bath actively again for 2 minutes.

Evaluate cleaning results and repeat this procedure only once (if needed) with clean IPA.

If you prefer cleaning with ultrasonic cleaner, we recommend to put a printed part into the container with IPA, close it well and put
the container into the ultrasonic cleaner filled with water. Leave it for no more than 5-10 minutes without additional heating.

If you use Wash and Cure station, leave the printed object submerged in IPA for 5 minutes. Depending on the results, you can repeat this step again and leave for additional 3 minutes.

It is easier to remove supports before post-curing. However, you can also post-cure a print with supports and remove them later. Depending on the model this can help to obtain better geometries if you have such goal. Post-curing time depends on your curing station, it can vary from 5 to 20 minutes. You should post-cure immediately after cleaning and drying. After proper post-curing, surface of DMD-31 printed objects should be completely non-sticky and very hard to scratch.
