3D printing nozzle, Multi-material 3D printer, Fab academy
Normally, FDM 3D printer can just be used for plastic. It has problem in metal. So this final project is a 3D printer nozzle for Sn, which will give more opportunity to designers to make their own demo, for example, it will push multi-material 3D printer to manufacture 3D PCB (print plastic structure and metal PCB together in 3 dimension)
This project is a multi-material 3D printer (it is called DM here) which can print plastic (PLA or TPU) and metal (Sn) in one model. This basic practice will help 3D PCB manufacture in future (in an ideal situation, the designer can print the structure and PCB together in 3 dimension which would save prototype’s space and time).
It would operate as the following:
- In fusion 360, we can design two parts (part 1 as plastic and par 2 as Sn), and then the output is in STL format;
- In Slice software(Cura), deal with the machine setting;
- Transport data to machine;
- In every lay, print plastic (nozzle 1 prints structure) first and then prints Sn(nozzle 2 prints Conductive Sn on PCB path);
- In special heigh(1 -3 position), pause the machine, and go to low default position;
- Sold component on model by hand;
- Continue to print
- Finish
