PETG for 3D printer

#1

Not sure this is the right place?

I’ve been advised by @lewisss (Thanks🤗) to use PETG instead of PLA which can warp with heat.

Where’s best to get it?

Thanks.

Filamentive is £30
Ebay £25
I’ll check filaprint later

#6

3dFilaprint with discount would be £26

Warning: Cheap is not always best when buying filament especially if you are looking for improved performance over PLA for your prints.

IMHO If it’s just for prototyping use PLA it’s cheaper under£20 per KG and for most object PLA is fine in fact I use around 30Kg/year at least and 95% of it is PLA

£1 won’t break the bank.

I have and will use PLA for prototypes

I’m ready for production on one model

The others should be fine for field testing at 0, 10 and 20% infill PLA

Not sure of any effects from heat generation yet. We’ll see very soon.

Finally ordered and received a reel of black PETG from www.3dfilaprint.com for £26 including delivery and 5% SLMS discount

Thanks @lewisss and @laurent_muchacho

Regarding use on the SLMS machine, do I simply select PETG in Cura or do I need to do anything else differently?

They also sent a leaflet advertising PETG carbon fibre? Is this compatible with the SLMS machine?

you need to set up a new profile on cura for the petg,

also as petg will be used at a higher temperature than pla you need to clean out the nozzle after use.

this consists of

  1. doing your print
  2. removing the petg
  3. insert pla into the machine (still on the petg settings)
  4. manually extrude for 10 seconds ,wait for 5 seconds (repeat 4 times) or run a small 2-3 minute print with pla but on petg settings.
  5. remove the pla.

and yes the new ruby nozzle means carbon fiber can be used

Thanks for the prompt and informative response.

The PETG label says:
Print temp: 195-220 degC
Bed: 35-60 degC

That’s quite a range. How do I choose or is it trial and error?

I might get some carbon fibre then…

For the Print temp go with the middle of the range for a start but ideally printing a temp tower test is the way to go. IMHO Taking the time to print one of those really save you a lot of time in the end and allow you to see undeniably which temp range is best suited.


or

I prefer the second one myself. Unfortunately with the new Cura 3 you’ll have to tweak the temperature manually as I didn’t found the “Tweak at height” plugin that use to work with Cura 15 it is worth downloading it just for that test print as it allow you to create a sliced object with automatic temp change

For the Bed @lewisss is the Master of using that stuff on U2 bed. I think he recommend going higher than 60 but better ask him
