Figure 1 Additive manufacturing principles

Source: (Dilberoglu, 2017) Figure 1 shows the following basic types of AM technology (shown from left): 1) Material Extrusion - laying molten material layer by layer 2) Vat Photopolymerization - selective lighting of light-curable material dissolved in a liquid 3) Material Jetting - laying the material in layers and subsequent curing 4) Binder Jetting - selective dosing of the binder for the connection of powder laid in layers 5) Powder Bed Fusion - melting of powder laid in layers COMTES FHT has available various types of AM technologies, Fused Deposition Modeling (FDM), Powder Bed Fusion (PBF) and Directed Energy Deposition (DED) technologies. FDM Technology uses the extrusion of plastic material and our parts are deposited by 3D printer Průša I3 MK3S. Another device called Aurora uses PBF technology is for depositing smaller metal parts and the last technology DED are available on two machines by Korean producer InssTek. There are two machines in our lab, InssTek MX 600 for industrial application and MX-lab for fundamental research. We are currently proposing to solve the AM process in the whole chain: part design, numerical simulation, additive manufacturing and finally evaluation of properties of additive manufactured parts. In each step there are many substeps, see Figure 2. (Darabi, 2021) (Urbánek, 2022) 6) Directed Energy Deposition – direct melting of powder material 7) Sheet Lamination –- glueing of individual sheets of material
