[Healthy 3D filament] Opening photoIt hasn’t been long since I started 3D printers as a hobby, but it seems that it is a time when I think a lot about the impact of 3D printers on our world. It seems that I came across the information on 3D printers while working from about ’17~’18 and discussing whether it can be applied to the field. At that time, the accessibility was somewhat low in terms of price, so the interest was not very high, but it seems that the era has come in which entry-level 3D printers can be easily obtained now. (This part will be discussed again later…) Today, we were selected as an experience group (2nd) conducted in a healthy 3D market, and we would like to organize the reviews of the 3D printer filaments. Just because you were given a filament free of charge, you don’t have to write a story that doesn’t exist. Anyway, there are a variety of popular 3D printer filaments on the market. In terms of amount, you can use the filaments that fit you at the range of 13500 to 19,500 won. The printer used was carried out with two Kingrun kp3s pro.(For comparison with the same setting value), the following are the items checked between use while being selected by the experience group. (The comparison target is esun PLA++) Whether spider webs are generated in consideration of odor comparison, temperature of use, retraction, etc. when printing.
