The printer on the right is homemade. The frame is a kit from ebay. I have the same frame kit i built my 3 color mixing printer with. It is not a bad frame with some careful reinforcements. The melamine wood it is made from transmitts acoustics a lot less than the all metal frames that just love to transfer vibrations. They can come out nice with some care. I assembled my ebay frame kit in 2016 and detailed it with a bunch of pictures in this thread right here: https://www.digitalcorvettes.com/thr...-stuff.270130/ . And then I have been having non stop fun with that ebay frame kit for the last 4 years non stop. And i detailed all that right here: https://3dprintboard.com/showthread....Mixing-Printer . The bigger IDEX printer is better for sure, but that smaller black machine can be a good machine. If you need or want my frame supports let me know and i will share all the files and you can print and brace up that frame.
