3D Printing
3D printing facilitates the creation of three-dimensional solid objects from digital data. Widely used methods include Fused Deposition Modeling, where the model is formed by small beads of thermoplastic, and Multi-Jet Modeling, which builds a model layer-by-layer using a print head. ColorJet Printing uses a color binder to solidify a core material. The different 3D printing techniques differ significantly in printing speed, resolution, color ability and costs.
The IPS 3D printer (3D Systems ProJet HD 3500Plus) uses Multi-Jet Modeling technology to produce high quality, durable plastic parts. Three different resolution modes (HD, UHD & XHD) are available. The printer is primarily employed to create solid models from microtomography volumes acquired at TOPO-TOMO and IMAGE. After the reconstruction of tomographic image stacks, segmented data from the volumes are converted into polygon surface meshes. Before printing, these digital models may be further manipulated by using specialized software packages. Another application is the production of specialized sample holders used for experiments at the different IPS beamlines.
