What is the difference between various FDM materials? The higher viscosity (thickness) or stiffness, the longer the print time or the smaller the layers. The various filaments are also available with varying melting temperature, maximum print temperature, melting agent%, cross-link density and average molecular weight. Before printing, 3D-print filaments should be heated for 20 seconds at 185 degrees Celsius to obtain optimal then durable adhesion at room temperature.

The technical structure of 3D printing is made up of a number of different technologies. On the first layer (generally being laser-cut), epoxy-glass fiber structures are printed in all directions, making up reinforcements, supports, stiffeners and the actual part. A second layer is printed on top of the first, forming a 3D cable, for instance, which is then reinforced by the third layer, etc.
This third layer is the resin. It flows under the direction of the heated nozzle, creating a shell around which your new part is built. The filament profile is melted and thereby filled with liquid resin. Once the print is completed, the cooled resin is then removed to leave a hollow object. The first printing extruder, however, also has a heated head to melt the filament and support its cross-section. This way, the strength of the first printing extruder can be optimized directly related to its support function.
When printing small-scale objects, the stereolithography process often provides the best results. However, large objects do not necessarily benefit from stereolithography technology because areas that are not designed to be sawed do not depend on support. d2c66b5586
