3D printing materials

New 3D-printing materials based on SVPE and Al

Together with Technopark Slava and LLC Russian Mechanisms, the developer and manufacturer of the first Russian industrial SLS 3D printers, InterPolyMech is developing new, advanced polymers based composite materials for use in 3D printing by selective laser sintering (SLS).


For materials intended for use in 3D printing, there are quite stringent requirements regarding the reological properties, size and shape of particles, their toxicity and other characteristics that can affect the manufacturing process and the final performance of the products.

The fluidity of the powder – the ability of the powder to move under the influence of gravity or rake in the printer, is due to its shape and will be maximum for spherical particles. To ensure optimal parameters of the printing process, powder particles should not exceed 100 microns.

We developed the first batches of the material and conducted tests on SLS technology, which showed the promise of using high-filled composites based on polyethylene (PE), ultra-high-molecular polyethylene (SVPE) and filler from dispersal Al (aluminium) to produce products based on them. Such composites are obtained by the technology of polymerization filling (PN). The fusion technology is similar to the existing industrial PE synthesis technology (SVPE) in the solvent environment.

Printed details from SVMPAnd al have shown truly unique insulation properties, as well as heat drain. and strength.

Areas of use

Developed composites are promising to use as thermal conductive dielectrics in the areas listed below.

Heat-leading materials for electric and hybrid car batteries

Thermoregulation is a pressing problem facing engineers today as electric car battery designers. The constant development of lithium-ion battery technology makes fully battery-powered electric vehicles an increasingly attractive option.

Heat-scattering dielectric composite materials as hulls of powerful batteries in electric cars

The battery module is placed between the plates of the thermal electrical insulation material, then this structure is placed in a metal body, which serves as a radiator at the same time. Depending on the battery used, it is possible to cool the radiator ribs with convection of air (forced), or with the help of winding from tubes, which carry the flow of the coolant.

 Application in LED technology

Developing materials to effectively drain heat and protect against electrical breakdown is an important task in the field of electronics and electrical engineering. This issue is most acute in the development of modern LED lighting devices. The current problem that scientific groups around the world are trying to solve is the low-efficiency diversion of heat from the warming elements of LED devices. Most of the electricity (about 75%) consumed by THE EDD is converted to heat and only 25% to light.
