my dad wants to drop crazy money on a 3D printing car parts business and i am stressing. advice? so my dad has this idea to start a business 3D printing rare and hard to find car parts to sell locally. he wants me to learn the modeling software and basically run the technical side of the project. honestly i am totally down to learn and help out but i am really terrified of this failing because of how much cash he wants to invest right off the bat. he is planning to buy two completely different types of expensive printers right away. the huge red flag for me is that where we live there are literally zero repair shops or technicians for these machines. if something breaks it is going to cost a fortune to fix if we even can. plus getting the actual printing materials and resins around here is super inconsistent and hard to find. on top of all that he said he is going to buy an autocad license. isnt autocad mostly for 2d architectural blueprints?…
