Layer adhesion for high grade plastics
With higher grade plastics the main problem is layer adhesion.
Because these plastics have a higher glass temperature, the ambient temperature needs to be higher for a good layer adhesion.
Old way of getting around this
With most printers this is done by printing in an enclosed chamber with a higher room temperature (an oven).
New method of getting better layer adhesion between printed layers on FFF type of 3D printing machines
Heating a specific part of the previous printed layer to "x" degrees.
- "x" degrees should be the temperature just under glass temperature of the material that is being extruded.
- The specific part that is heated, is just in front of the filament that is going to be deposited.
