I’ve now tried various Rigidink PLA filaments (fun packs, testers and spools) all build really well and the colours come out great! Really vibrant and bright. Once you tweak your printer settings and get one building good, you can simply use whichever filament colour you like with no problems or changes. Print well fast and at 0.2mm layers, going to build more detailed parts using smaller nozzle dia/layer thickness - I know they’ll turn out great already! Best filament I’ve used!!! Top quality, highly recommend!!!!
PLA 1.75mm Fun Packs - 5 x 10m Samples
Once I found a temperature where it would stick to the bed, it printed well enough but it didn't seem any better than the Makergear filament I use.
It would be cool if you could provide advice on how to handle small 10m samples
After a disappointing experience with another suppliers set of samples where the translucent sample caused a number off issues including hot end clogging and delamination during printing it felt like a gamble testing the sample translucent pack from Rigid Ink. I am glad to say the Rigid Ink samples stand 'clearly' head and shoulders above those I previously tried.
