The main objective of the 3D Laboratory at the Department of Physics is to provide university students and academic and research staff from other departments with the knowledge, skills and tools to use various 3D technologies to solve problems of varying complexity. It is a purpose-built workplace equipped with advanced 3D technology, software, and skilled staff, set within the academic ecosystem of the University.
The Department of Physics currently has four high-quality 3D printers that use two additive manufacturing technologies.
Fused deposition modeling (FDM) technology
The basic principle of FDM 3D printers is that the printer applies the molten material in layers onto a work platform until the part is completely finished. FDM technology uses digital design files that are uploaded into the machine itself and transformed into physical dimensions. Materials for FDM printing include polymers such as ABS, PLA, PETG and PEI, which are fed as filaments through a heated nozzle.
The Department of Physics currently uses a Zortrax M300 Dual printer for FDM printing, with a build volume of up to 265x265x300 mm and an Ultimaker S7 printer with a build volume of up to 330x240x300 mm, allowing the printing of both quite large parts or many small parts. Layer heights are 0.15-0.30 mm and 0.06-0.30 mm respectively. Printing smaller layers produces smoother parts and more accurate reproduction of curved geometries, while printing larger layers allows parts to be produced faster.
Liquid-crystal display (LCD) technology
The basic principle of LCD 3D printers is that the working platform is lowered into a resin tank with a transparent bottom. The printer uses a digital projection screen located under the resin tank to project an image of the layer across the platform, simultaneously curing all points at once. Parts are built upside down, layer by layer, until the part is completely finished. The LCD printing process uses a liquid photopolymer resin that has the property of curing when exposed to light of a certain wavelength.
The Department of Physics currently uses a Zortrax Inkspire printer with a build volume of up to 132x74x175 mm for LCD printing, designed for detailed printing of small and medium-sized objects. Layer height ranges from 0.025-0.100 mm. Printing smaller layers produces smoother parts and more accurate reproduction of curved geometries, while printing larger layers allows parts to be produced more quickly.
