I bought a desktop printer to print parts of an open source project. I think the original words in the project are: ABS is better than PLA, and PLA is also OK. Then I consulted the merchant and he said that the strength of the light-cured parts is not enough. As a result, the parts printed by my FDM could not be closed. I regret it a little bit, I feel that it is not as good as light-curing, and the price is not much different.

No best answer

See if there is any possibility of upgrading, or purchasing higher precision, now the precision of motor drive equipment is very high.
