  • For die casting, it is post processing. After the part comes out of the mold there is the sprue, overflow tabs, and flash (extra material at the parting line) that needs to be cleaned up. Then the parts are often chromate conversion coated and then finished with either a wet paint or powder coat. Plating is also an option.

    For injection molding, parts typically come out of the mold fully finished (or just requiring gate removal). The vast majority of parts are only textured where the final finish is part of the mold. You can do anything from a high polish to rough textures, or even any crazy pattern or simulated material you can imagine. For graphics you can apply in-mold decoration where a film is placed in the mold before the plastic is injected. There are some post processing finishes that are pretty frequently done such as wet painting and plating.





  • The article more or less covers it. Asian countries without a credit card culture mostly transitioned to QR because it was easy with minimal equipment changes required. Those with widespread credit cards accept tap and QR (e.g. Taiwan widely accepts QR payments, Google pay, Apple pay, credit cards, and transit cards).

    Since the western world has been on credit cards for decades that is the solution that is accepted there with QR payments being almost exclusively in businesses that have a customer base from Asian countries. Even then the US is odd compared to other countries since they never really adopted chip and pin.



  • Not uncommon but lots of printers on the market (especially hobbyist ones) are kits that you need to assemble. Bambu printers are pretty much remove the printer from the box, remove some brackets, tape and protective packaging before installing the build plate and spool holder and turning it on.

    I’d recommend going for the P1S if you can swing it over the P1P for the enclosure.


  • I agree with the suggestion, Bambu A1mini is the only printer in that price range I would be willing to purchase and expect for it to work properly. While there are plenty of people happy with their Creality and Sovol printers, they often end up being project printers that require a lot of tinkering to keep them running well and those that aren’t prepared for that shouldn’t buy them.

    I like to say there is two different hobbies here, if you want 3D Printing to be you hobby, then spend the money on a known reliable printer, if you want 3D Printers to be your hobby, then buy a cheap printer and get ready to tinker.

    A couple other people have recommended resin printers, which are probably better for that you want to do. But be aware that resin is pretty nasty stuff and you need to have the printer in a very well ventilated area and should wear all the recommended safety equipment. You shouldn’t get into resin printing unless you are aware of safety requirements which are often downplayed by people who own them.
