3D Printers, Extruder, Scanners, and cost.
When we imagine, the 3D printed product material comes first. 3D printing material is essential, and it should look like a filament. So the first thing that comes to mind is how we can make the desired filament that can support maximum heating temperature and speed to make a part.
3D-printed hydrogel electronics for biomedical and environmentally friendly applications can lower the device cost.
