I started 3D printing when I was 22 years old and studied “Physics and Nanotechnology” at DTU. The first time I really got introduced to a 3D printer was when a friend of mine explained how he could print a replacement part for a cooker instead of replacing the whole cooker. This possibility of replacing parts instead of buying new ones made so much sense for me that I eventually bought a 3D printer. I purchased a 3D printer from the brand PRUSA and some plastic/filament, so I could start printing. The first thing I ever printed was a Batman logo which I still got (you can argue that it is not that useful, but I like it 😉
I later found a drawing program on my computer and learned to create 3D drawings. I am not an expert, but I can draw most things by now. After you have drawn the objects, you cut the two drawings into 2D slices with a slicer (you can get the slicer program on the computer), so you know how to a print the model you have drawn. I have printed several other things than the Batman logo, for instance, a lampshade, Settlers of Catan game, coat racks, protectors for the chairs in our kitchen, and a lot more. There are just so many things you can print, which today makes my 3D printer one of my best tools!
Settlers for Catan
At the beginning of the Covid-19 shutdown, a movement of people started to print face shields for health care workers. I joined the group, and five days after the shutdown, we were able to print around 2000 face shields a day. It was great to be able to help out and make a difference.
I would suggest that if you need something 3D printed, are interested in 3D printing, or just want to try it out. Then find a friend you can borrow it from or invest in one yourself! Even, if that is not a possibility then seek out a 3D printer at a university, a lot of them have printers you can use.
It takes some time, and you have to put some work into learning how to use a 3D printer, but you can get a lot of help from online communities. Even though it might be hard in the beginning, it is very satisfactory to produce something you can use in your everyday life.
