Standard Vinyl that contains PVC should never be heated with a Laser. It will create corrosive chlorine gas.
Any advanced Vinyl like PVB, PVA or any variant that does not contain chlorine can be cut with diode co2 and fiber without issues.
I went down that road first building a plotter attachment then trying to attach a knife on an ender 3. Kinda got it to run by simply extruding svgs into a 1 layer body that i could then “print” with a standard slicer. In the end i build myself a laser, and let me tell you, everything before was a huge waste of time :) the laser cuts like a beast, much faster and cleaner. Would not recomment using a knife in a laserworld.
If you are oke with the smaller volume, this is a good printer. this thing will be able to print flawlessly, all parts are semi open source and there’s a great community if you need support parts or any help. Prusa is above average stuff.
On AliExpress you can buy 30 colors pla for 7€ as a set for 3d printing pens.
Nope, it is not significant. The only thing that really stands out is the runout sensor with loading function function that is sold for 2.0, if you dont need that, print ninjaflex 24/7 and your 1.5 has no direct issues there is no need to upgrade.
If those 2 are from the same job its either a sagging gantry on an ender or the bed/mesh is not tilted properly or not meshed/leveled properly. Check squareness and sagging gantry, then check mesh/level after.
Oups misread that
Just jumping in here, the first layer does look kinda shitty, at least theres a lot of room for improvement.
Here’s a little guide to improve on a multitude of things by teaching tech.
Cool cura feature thou :)
Im using a filament fuser 3d printed. Try looking for filament fuser/welder/connector on thingi or any other page. There are also professional solutions on the market but diy cheap printed thing works flawlessly for me.
I simply attach it to other filament leftovers and print stuff with it where color does not matter.
Well depends on the actual material you are using. Just google PVC free vinyl, you can buy the stuff in any form. If you find sth for your application a laser is perfectly fine.
