Trying PETG for the first time. Really good filament.
I liked the sample PETG enough to buy a spool, It’s pretty nice, though I’m still dialing temp’s in.
I have some, but I have to figure out what it sticks to and what settings to use.
Nothing against you. But I see and hear some thoughts of people all the time. Like this one here. You print a one-walled object or maybe just 2 perimeters and say its good. You wont have any warping issues, no overextruding-issues and so on.
And others say “Iam not having any problems with XXX” which is the same. The only print figures/statues and such with little to no infill.
Still PET/PETG is nice but if you start printing really usable things, mechanical things youll run into troubles.
I prefer the (Micro Center) Inland PETG over their PLA, but its a little more expensive so for just some crap part I still just use PLA. But Inland PETG I print 235C 90C and have no problems at all with sticking to the bed and I have found that PLA cracks under pressure more easily than PETG- PETG is definitely more flexible and stronger (in particular in Z layer adhesion) than PLA in my somewhat limited experience.
@VolksTrieb
That’s why I print mostly in ABS or alloy 910.
These prints tend to crack with ABS but petg is ideal.
I find that ABS is practically unusable because the layers separate so easily- it needs a heated chamber or at least an enclosure to retain the heat I think- but even then probably the layer adhesion is not great.
@Ted_Huntington
well which speed and temp? Some are warping a bit and some filament is crap but in general with good filament I can get it as tough as injectionmolded. Ive got no heated chamber, but its enclosed and the heatbed warms it up a bit.
@VolksTrieb Usually 40 mm/s 250C/110C - yeah maybe it is the filament I use- the Inland ABS from Microcenter. Wow that’s amazing that you find it to be as tough as injection molded- what filament do you recommend?
@Ted_Huntington well the very best ive ever used in abs is still extrudr abs (http://extrudr.eu). Also ive got me some used ultimaker ABS which is nice too. Needs more temp but doesnt even warp when printed at 100% infill (lol). Normally up to about 60mm/s 240 deg is enough and I think my thermistor is even reading too hot. Maybe its just your filament but I would recomment using a thermocouple and multimeter to check your temps. Maybe your just printing top cold.
Incredible quality!
@VolksTrieb Thanks Lord V, I basically just use the cheapest filament that works and so use mostly PLA and now PETG- yeah I use a laser temp device and thermistors so I’m sure my temp is ok- could be old filament- there are a lot of variables.
I just started using PETG as well. I haven’t printed much but all the parts I printed had infill. It does overhangs very well and it’s more durable than my ABS but without any of the printing trouble. I printed a couple mechanical parts which function fine but they don’t have a lot of strain so I’m not familiar with any problems @VolksTrieb might be hinting to.
