About two weeks ago I bought my very first 3D-printer – a Creality CR20 – at one of the few dealers here in the Netherlands. I also got a spray-can of 3DLAC (adhesive for the plate so the prints will stick) and 1 kg of white plastic PLA filament.
The measurements of the printer are 42 x 41 x 47 cm. The build plate supports up to 22 x 22 x 25 cm and can heat up to a 100 degrees. The printer weighs 7.5 kg and has a 0.4 mm nozzle (type MK8). I got an extra 0.2 nozzle a few days ago, but haven’t tried it yet.
The printer was easy to assemble as it only came in 2 parts with 4 screws to put the frames together and 2 screws for the filament-holder, mounted on top. A few wires labeled X, Y, Z had to be connected to the corresponding sockets. The whole process took about half an hour and with the sample filament that came with the printer, I inserted the filament into the extractor tube and was ready to give it a go.
The SD Card that came with the printer had a few example project on it. The first thing i printed was a dog (5 x 5 x 6 cm + 30% fill). It took about 3 hours to print. The first print felt like magic and I was very impressed with the end result. The next test was a print of 2 cubes, one with 50% fill, and one with 100% fill. These took all night to print – about 11 hours. Pretty cool, but I wanted to make my own designs.
I purchased a course on Udemy the next day and designed a few of things in Fusion 360 (CAD by Autodesk): a coat hook, a pair of tweezers, a vacuum Nozzle and a small wrench.
