1. What does 3D printing actually mean?
3D printers apply materials layer by layer.
The control is done by a 3D printer software, the Slicer Program.
The Slicer Program generates a Gcode that the 3D printer can process. The basis for this is a 3D model which can be designed or downloaded.
The 3D printer software can be used to set various parameters. For example Layer height, temperature, speed and much more...
2. Which filament is best?
Each material has its advantages and disadvantages.
PLA has the advantage that it is easy to print and no unpleasant odours occur.
ABS has the advantage that PLA has a higher temperature resistance, but a closed build chamber is recommended.
ABS is somewhat more difficult to process and has a slight plastic odour. However, a high-quality ABS can also be processed very well.
There are now many other filaments with great properties, e.g:
PET, PETG, TPU, TPE, Nylon, Polycarbonate and many more.
3. Which filament diameter do I need?
We distinguish between two filament diameters: 1.75 mm and 2.85 mm.
There is no right or wrong diameter.
Depending on the 3D printer model, a different filament diameter is required.
4. Where can I download free 3D models from the internet?
There are many 3D printing databases. The most important ones can be selected here:
5. Which 3D printing processes are available?
There are different 3D printing methods. The most frequently used 3D printer method in the desktop area is FDM printing, since printers and printing materials (filament) are inexpensive. FDM stands for Fused Deposition Modeling.
Other common printing methods are:
DLP - Digital Light Processing
SLA - Stereolithography
SLS - Selective Laser Sintering
MJP - Multijet Printing
6. What materials can a SLA/DLP printer handle?
SLA and DLP printers use synthetic resin.
7. How can I get better adhesion of my components?
A heated prin bed and a print surface are recommended so that 3D prints adhere better to the printing bed.
