so as i am in the process of giving my ultimaker origonal a serious overhaul (dual fans, heated bed, enclosed build chanmer and multiple new parts) I realise that to print some of these new parts (espcially parts that will be subjected to a lot of heat or strain and pressure) its best to print them in ABS
so as someone who has never used ABS, only using PLA, what is the best method to
1) prepare your printer to print ABS, so purging it etc
2) best wat to get ABS parts to print and stick to your heated bed
3) getting my printer back to printing PLA
also any advice on characteristics of ABS, i have heard it can smell quite nast. i keep my 3D printer in a cupboard in the middle of my house, could this cause any problems?
Many thanks everyone!
