CENTER OF ADDITIVE AND REGENERATIVE MANUFACTURING AND ENGINEERING (CARMEN)

Responsible person: prof. Ing. Radovan Hudák, PhD.
Location: Letná 9, main building, ground floor B-block, room B-P008

Focus of the laboratory

The laboratory is primarily intended for 3D-bioprinting of heterogeneous objects and hydrogel constructs based on a digital CAD model, using an additive manufacturing method. We are currently developing our own biomaterials based on polymer cross-linking and testing them in the 3D bioprinting process. Within the laboratory, we have the technology of Fused Deposition Modeling (FDM), Injection pore filling (IPF) and Injection volume filling (IVF).

FDM – the principle of this technology consists in melting the filament in the print head. According to the so-called He applies the G-code to the mat and the object is created layer by layer.

IPF - technology of injection pore filling (IPF) allowing to select specific layers on which cells will be injected into selected pores. This also allows the injection of controlled amounts that may even be different in each individual layer. This technology increases and guarantees the survival and viability of cells in extreme conditions, such as in the case of working with thermoplastic polymers at high temperature.

IVF – it is a technology that uses 3D-bioprinting directly of the hydrogel from the injection cartridge.

The laboratory was created with the support of CEMBAM and OPENMED projects

LABORATORY OF COORDINATE METROLOGY

Responsible person: doc. Ing. Teodor Tóth, PhD.
location: Letná 9, main building, ground floor B-block, room. B/P012

Focus of laboratory

Coordinate measuring machines enable touch and non-touch assessment of the accuracy and quality of component production. the Contura G2 CMM is a gantry type for high-speed scanning. It is designed for measuring specific elements, in a number of positions with different angles and for small sensor configurations. The rotating Zeiss RDS measuring head allows measurement in 20736 positions and rotates in 2.5° increments, and with the support of Vast XXT technology it can scan in all positions. Computer-Aided Accuracy (CAA) technology ensures correction of kinematic deviations to achieve extremely accurate results.
Calypso evaluation and service software, based on CAD technology, enables object-oriented creation of CNC measurement programs. Fast and accurate scanning of known geometric shapes (circles, cylinders, cones, planes, ...) is ideal for efficient measurement of parts with a large number of tolerated parameters. Scanning known profiles (contours) of curves and general surfaces, as well as unknown curves, is ideal for digitization in tool and mold manufacturing. The HOLOS and GEAR superstructures are used to measure general surfaces and gears.
With the help of a coordinate measuring machine, it is possible to check the dimensions, shape and positional deviations of the parts.
