I had my whole family visiting over the Memorial-Day weekend and we all had a lot of fun. On Monday my oldest son brought over a bunch of fidget toys he printed with his 3D printer. All of the kids loved playing with them and it got me thinking about how far the technology has come since I purchased my 3D printer. The printers you can get today are much more advanced and can do many different things.
My oldest son had a neighbor who got into 3D printing as a business. Every time the neighbor upgrades his printer, he gives the old one to my son. While my printer can print a single color, my son's can print multiple in the same print. There are a number of ways to do that. My son's printer has a single print head (where the hot plastic comes out of) and so it creates purge blocks where it dumps the previous color while waiting for the new one to be ready. Sometimes those purge blocks can be larger than the object you are printing and so you want to be careful with how often you change colors. My son's neighbor has a more expensive printer with multiple print heads, lessening the need to use purge blocks on color changes.
The fidget toys my son brought to our Memorial-Day celebration had multiple different colors and looked very nice compared to what I can print. My younger son who also has a 3D printer also expressed praise for the print quality. This had me asking if I should upgrade to a higher quality printer.
Truth be told, I don't have a lot of use for a 3D printer. Mine sits idle most of the year. About the only time I use it is during the Christmas Holidays when we create ornaments or small and inexpensive gifts for neighbors. It does not make sense for me to upgrade something I rarely use. Would being able to print multiple colors change that? Not really. For me, there is not a compelling reason to upgrade. That being said, there are a number of people using their 3D printers all the time and newer technology will improve what they are making.
