3-D tiskanje trajnih magnetov

Buh, Robert (author), Marinšek, Marjan (mentor)

Trenutne oblike magnetnih materialov za elektromotorje so zelo enostavne zaradi tehničnih in ekonomskih razlogov. Tehnologije dodajalnih procesov, med njimi tudi 3D tiskanje, pomenijo korak k novejšim, bolj naprednim oblikam elektromotorjev. Za to nalogo moramo imeti ustrezen magnetni material, ki odgovarja izbranim parametrom obratovanja. Tak material nato z ustrezno tehniko 3D tiska pretvorimo v trajni magnet v poljubnih dimenzijah ali oblikah, ki jih je z ustaljenimi metodami zelo težko izdelati ter ob tem ne pridelamo veliko odpadkov. Za uspešno vpeljavo 3D procesov v industrijo morajo tridimenzionalno natisnjeni izdelki konkurirati konvencionalno proizvedenim. Za ustrezno primerjavo sem iz dosedanjih študij 3D tiska izbral najbolj obetavne in jih primerjal z obstoječimi po času in natančnosti izdelave, fizikalnih in mehaničnih lastnostih magnetov ter magnetnih lastnostih. Za zaključek sem poskusil napovedati, če se bodo tehnologije 3D tiska uspešno integrirale v industrijo ali pa bodo ostale na nivoju izdelovanja protitopov in modeliranju.

• Title: 3-D printing of permanent magnets

Abstract

For its technical and economic reasons, current designs of magnetic materials for electromotors are fairly simple. Technology of add-on production, involving 3D printing, represents a step towards newer and more advanced electric motor shapes. For that we have to provide a certain type of magnetic material, which is transformed into a permanent magnet via 3D printing, which is capable of creating certain shapes of magnets, nearly impossible to create with conventional methods, and produce next to zero waste. If we want 3D printed permanent magnets to become a part of the industry, three-dimensional products must compete with conventional products. To have an adequate comparison, I compared magnets, made by add-on production with conventional production, by comparing creation time, accuracy, physical, mechanical and magnetic properties. To conclude I tried to predict whether 3D printing technologies will succesfully integrate themselves in the industry or will remain as a prototype and modelling tool.
