Harz Labs Cast Resin Review

About company

Company HARZ Labs was founded in 2017, in Moscow, after many years of research and development in the field of polymer materials. Putting high-quality raw materials, its own innovative developments and modern industrial production at the head of the company’s values, HARZ Labs in three years was able to conquer not only the Russian, but also the world market of polymer materials.

More details about how the company HARZ Labs was created, Andrey Adamov told in an interview to Alexander Kornveits, which you can watch on our youtube channel .

Now HARZ Labs supplies its products to more than 50 countries around the world and offers a wide range of materials for DLP, LCD and SLA printing.

Materials for 3D printing

The main difference between all HARZ Labs photopolymers lies in the very high level of detail and precision in printing. They give virtually no shrinkage, making the print result stable and predictable.

Another feature of resins is the almost complete absence of odor, which is what everyone who works with a photopolymer 3D printer dreams of. The hypoallergenic and safe for health composition makes HARZ Labs materials the most comfortable to work not only in laboratory conditions, but also in rooms without special ventilation.

Basic photopolymers

The HARZ Labs standard line consists of Model Resin, Basic Resin and Art Glow decorative resin.

Basic Resin is the basic, easiest to use material for daily use. Even mistakes in print settings will not prevent you from getting a decent result. That is why it is recommended to be used in educational institutions, in the office and at home for those who are just starting to master 3D printing.

Model Resin – Designed to print rigid, durable models for functional use. Finished products are resistant to both mechanical and physical stress, for example, to high temperatures (up to 100 C). And HARZ Labs even has videos of them hammering Model Resin nails into a log.

Model Resin is available in five intense shades: black , white , gray , blue and cherry . And also in natural transparent and pure transparent . The latter, by the way, is perfectly tinted and can be the basis for creating your own color.

Art Glow resin is intended for printing decorative patterns. It contains an intense fluorescent pigment that provides a bright green glow for up to two hours. With Art Glow, you get very effective glow-in-the-dark models!

Dental photopolymers

HARZ Labs timely estimated the lack of proposals on the dental photopolymer materials market. With a focus on dentistry, they have created a line of high-precision photopolymers at the most affordable cost among the competition. Largely due to the availability of high-quality consumables, laboratories have begun to actively introduce 3D printing into their daily work.

HARZ Labs’ extensive line of dental resins includes 9 materials for a variety of applications. All of them are certified, made from class 1A biocompatible raw materials and meet the requirements of GOST-ISO 10993.

Dental RO is the latest innovation from the company. It is a radiopaque polymer specially developed for the manufacture of computed tomography templates. CT scan results with a Dental RO resin template help to more accurately match the position of the teeth and the simulated model that will be used during surgery. It is impossible to use a template made of this material during the operation, since it has a dense white color and does not give the desired view. But to make sure of the accuracy of the model – you can, thereby, dentists exclude the possibility of any mistake when creating a surgical template.

It is logical to assume that there is a special polymer for printing the surgical templates themselves. This material is Dental Yellow Clear resin . It has a transparent yellowish color for good visibility of the work area. And the finished models have a very high accuracy and special rigidity, allowing you to firmly fix the template in the patient’s mouth.

Andrey Adamov has successfully tested the accuracy of his polymers on himself.

Another transparent polymer in the line is Dental Clear . The polymer has a transparent color, without any shades, which somewhat expands the scope of its application. It is used to print not only surgical templates and demo models, but also aligners and aligners. Now more and more laboratories are choosing to print aligners on a 3D printer instead of vacuum forming technology. Not surprisingly, 3D printing saves not only time, but also resources, making the service itself more cost-effective and efficient for both the clinic and patients.

Dental Peach is exactly the same photopolymer that is suitable for thermoforming aligners and other corrective devices. It has a short-term stability at a temperature of 180 C, and a long-term one at a temperature of 100 C. It also has mechanical strength, which makes it possible to make demonstration models and master models from it.

Photopolymer Dental Pink – used for 3D printing models of gums and gum masks. The resin has a pink color very close to the natural color of the gums. It is quite easy to work with, so it can be used for printing and other products.

Dental Sand series A1-A2 , A3 and Bleach photopolymers are designed for printing temporary crowns and bridges. It is a composite polymer with ceramic micro-filling, similar in properties to PMMA material. Finished products are highly resistant to aggressive environments such as acids and alkalis, as well as mechanical stress. The colors correspond to the Vita scale.

Dental Cast is a photopolymer for creating models for direct casting. The resin has very high detailing and zero ash content. The resin burns out quickly at high temperatures, no residue. It allows the manufacture of high-precision metal and ceramic crowns, bridges, dental implants, arch prosthesis, etc.
