Harz Labs Dental Sand 3D Printing Resin

Description

3D printing resin Harz Labs Dental Sand is a resin with PMMA-type ceramic micro filling, made of biocompatible raw materials. Available in shades: A1-A2, A3. It has high durability and high tensile strength, resistant to mechanical and chemical effects. Recommended for printing models of temporary crowns and bridges. The slight odor and lack of hazardous monomers allow for using it even in a small laboratory.

 

Russian certification. Product without european certification, to be used only for models.

COMPATIBLE WITH MAIN DLP/LCD 3D PRINTERS

Advantages

 

• STABLE COLOR

  Depending on postcuring condition. Bleach color is achievable. It is stable for a long time even in aggressive media.

• DURABLE

  Pigments and fillers are well stabilized, no sedimentation and flocculation occur ang no foam appears.

• LOW SHRINKAGE

  Shrinkage less than 0.5% gives you the same size of the 3D model on your computer.

• SAFE

  Resin does not contain solvents and volatile monomers, irritating compounds. No fumes, odor and allergic reaction. Сan be used in lab or even at home. 

• BIOCOMPATIBLE

  Produced from biocompatible raw material used in photopolymer teeth fillings. Meets the standard ISO 10993.

• UNIQUE MECHANICAL PROPERTIES

  Very high hardness, tensile strength, abrasion and scratch resistance due to ceramic fillers.

• CERTIFICATION

  Biocompatibility was confirmed by the third-party laboratories. Material was successfully tested in accordance with ISO 10993 with the provision of the MA No. RZN 2020/12007.

Finishing Instructions

 

1. To clean and remove excess resin, flash the 3D printed part for 30 seconds, several times until excess resin is removed, in an ultrasonic cleaner with TEK1960* .

2. Do not soak in acetone. Do not leave the 3D part soaking in the liquid. Use a soft brush if necessary.

3. Clean off any excess of liquid with a cold blowdryer or compressed air.

4. Leave under the sun or in a UV lamp to cure. The resin is fully cured when fingernails do not leave scratch marks on the object.

*We do not recommend the use of denatured or isopropyl alcohol (IPA). It is very aggressive on the polymerized resin and it could weaken the structure of the 3D part. It is also flammable and potentially harmful to people and the environment.

Store the resin in a dry, cool, shaded place out of direct sunlight.
