Sticks PLA printer filament. Causes death.
on 10 January 2016
Works wonders with PLA 3D printer filament. That's what I'm going to waffle on about here; I can't comment on how it works with other plastics.
Bit of a warning about how totally evil this stuff is in the last paragraph.
PLA (Poly Lactic Acid) is a type of plastic - actually derived from corn starch - that is used by many 3D printers. Like the replicator 2 that I own.
It took me ages to find something that would stick printed parts together; I tried superglues cheap, expensive, thick and thin consistency, two part epoxies (limited success and AWKWARD). You name, I failed with it.
THEN I came across this stuff. Fantastic.
This is pure Dichloromethane. (AKA "Methylene Chloride", "Dichlo" or "Diclo"). It says so on the label.
It isn't a glue. It's a solvent. It dissolves the PLA, and very rapidly evaporates.
So I've been applying this to printed surfaces with a modelling brush, then VERY QUICKLY pressing the parts together. Believe me you have to be quick. It evaporates so quickly that you only get 2-3 seconds to get the parts together. Because it evaporates so quickly, the bond is INSTANT. There's no chance really of repositioning.
That's all the good stuff; here's the bad:
This is a NASTY NASTY chemical. It is harmful to everything, including you. Mostly I ignore 'elf 'n safety, but not in this case. It's defintiely Carcinogenic. It definitely knackers your skin up. It definitely kills your eyes. I googled it and was horrified; I would stop using it but there's no alternative. So use in a very well ventilated area. Put the top back on immediately. Don't fiddle about with the next bit to be glued while the top's off. Don't get any on your hands.
Apologies if that sounds preachy, but this is stuff warrants caution.
