When using 3D printer, bad news material also is the key that deciding finished product character. Because some users won't discern the stand or fall of bad news material and used the bad news material with a few poorer quality, can appear so odour is bigger, finished product becomes warped easily edge, printer shower nozzle blocks a head up easily, wait for the problem that invites poll to ache. Enter pit to make these users avoid, below small make up everybody to gain ground below, how to discern the stand or fall of material of the 3D bad news that print.
One, naked eye observation
Discern namely according to explicit condition: Open sealed hind, can observe whether wire has off color first, whether does the surface bend not straight, whether does interior have spot, bleb, dirt, observe whether colour and lustre is even even, if colour and lustre is inhomogenous,the specification produced change.
2, precision
1, can check with feel, pull open 1 -- the bad news capable person with senior 2m, break bad news material with the hand, perhaps pull slowly use wire, the hand can be felt very easily, surface of bad news material is slick, size of degree of finish is even.
2, use instrument test, with 1 -- the bad news material of the length of 2m will use the vernier calipers that contains number to show to measure, the common difference that checks line means is even, diametical error is big, whether be inside limits of pilot public errand, the public errand of average cost material can be controlled it is in 0.05mm, every check a place, rotate a week is measured 3 -- 4 circumferential, material watching bad news whether " round " .
3, the process that print observes
1. The more inferior bad news material, flavour the more pungent, because contain more additive, heat commonly the gas that melting is meeting hair is more also. In the process that print if appeared to compare pungent flavour, need instantly out of service.
2. General 3D printer is being printed begin to want to do substrate, the even rate that watchs shower nozzle to go up in substrate, if print evener, so control of precision of bad news material is inside limits. If bad news material is inhomogenous, bad news material can have when taking the unit of makings through gear " throat throat " gear attrition sound, below the circumstance with bad news even material criterion won't.
In recent years, the rapid development that 3D prints, bad news material also jumps over diversification more more, while the hope is developing new material, to already some bad news material also should be improved continuously, the use 3D printer that makes more users safer be at ease, also can promote popularize more capacious crowd in the center.
