— It dissolves in esters, acetone, ethyl acetate.
— The density is 1.02-1.06 g / cm³.

— Preparation of parts for 3D printing.











FDM (Fused Deposition Modeling)  — production technology, widely used in the creation of three-dimensional models, in prototyping and in industrial production.

FDM technology means the creation of three-dimensional objects by applying consecutive layers of material that repeat the outline of the digital model. Typically, as materials for printing are thermoplastics, supplied in the form of coils of yarns or rods.


— The process of printing to a 3d printer.











3D printing is finished.


For the prototype, also, another type of 3D printing was applied (SLA technology)

SLA (Laser Stereolithography) — one of the technologies of rapid prototyping.

This method differs from the others in that it uses as a «building material» not powders, but photopolymers in the liquid state. In a container with a liquid photopolymer, a mesh platform is placed on which the prototype is «grown».

With the help of this technology, a three-dimensional object designed on the computer is synthesized from the liquid FPK by successive thin (0.05-0.2 mm) layers formed under the action of laser radiation on a moving platform. As a rule, the processor for forming horizontal sections preliminary transforms the description of the 3D model of the future object from the STL-file format into a set of stratified sections with the required pitch in height.

  • Accuracy of printing — 35 microns;
  • Material — standard photopolymer.
