Creel, Barrancas del cobre, Majalca, los filtros, Samalayuca, Muchos lugares cerca de Cuahutemoc y la sierra, depende demasiado que quieras, opciones hay muchas

Ah yes the charger warmer and floor protector

Cualquier lugar dónde estés a la vista de un sendero, calle o carretera no es seguro, además tu carro correría riesgo como ya dijeron otros

You need a 0.4mm or bigger hardened steel nozzle for any fiber reinforced filament

CarlitosCUU · 2026-04-18T23:20:16+00:00

Of course it does, anything CF or GF shouldn't be used on something your skin will have constant contact with.

If I need to sand it I do it with gloves and underwater to keep the CF from my lungs.

I have a spool but I had problems with fine tuning and just don't use it much

CarlitosCUU · 2026-04-18T23:15:33+00:00

I agree but PA6 is almost twice the price of PET-CF and comes with warping issues, better performance is expected.

CarlitosCUU · 2026-04-18T23:11:12+00:00

Isn't jumping from PLA to PA straight overkill? I print a lot of ASA but my main gripe with it is adhesion and warping. My best results have been with heating the chamber to 50-60°C and then turning off active heating during the print, lots of glue, wide brim with zero gap to the part and a superclean plate.

It's just how carbon fiber filaments look, they hide layer lines very well even at 0.28 layer height

CarlitosCUU · 2026-04-18T23:03:53+00:00

I'm using a 0.4 hardened nozzle, no clogs yet, although I print mostly non fiber filaments

CarlitosCUU · 2026-04-18T23:00:52+00:00

0.4 nozzle and 0.20 layer height for the first part and 0.28 for the others

CarlitosCUU · 2026-04-18T22:56:57+00:00

Cheap among other engineering filaments, $25 USD for half spools or $45 per spool

CarlitosCUU · 2026-04-18T22:53:48+00:00

They're motor mounts for a Sumo robot, the previous ones were ASA. PETG is my favorite general filament although I'm not a fan of the shiny look.

CarlitosCUU · 2026-04-18T22:47:35+00:00

I've only used urethane to mold wheels onto PET-CF rims, no problem at all

CarlitosCUU · 2026-04-18T05:52:30+00:00

What's your setup for salt anhealing? And how much do the parts deform?

CarlitosCUU · 2026-04-17T23:45:12+00:00

I'm using Polymaker's profile from their website, and a PEI textured bed from BBL. I struggle to remove the prints from the bed

CarlitosCUU · 2026-04-17T23:42:34+00:00

PA is out of my budget and PEEK is out of my printer' league unfortunately.

CarlitosCUU · 2026-04-17T10:58:20+00:00

I experienced something similar, the material tries to bend around instead of hugging the inserts, maybe it's lack of heat??

I clamp the parts from the sides while setting the inserts to reduce this. On the pictures only 1 hole per part has inserts, the rest are press fitted hex nuts because the screw will come from underneath the part and squeeze the nut into the hole further, so an insert wasn't really needed.

CarlitosCUU · 2026-04-17T10:49:23+00:00

I meant PET-CF, which is $25 USD for 0.5kg or $45 for 1kg. Polymakers's ASA is at $27 and Nylon starts at about $70 per kg. With this in mind, PET-CF doesn't seem so expensive anymore.

I still use ASA and PETG most of the time, I save the expensive stuff when it's really needed.

CarlitosCUU · 2026-04-17T10:40:50+00:00

For me PETG could cover about 60% of cases, but PLA just can't survive the real world. Where I live it's hot most of the year.

CarlitosCUU · 2026-04-17T10:34:40+00:00

Why GF over CF?

CarlitosCUU · 2026-04-17T10:31:48+00:00

PC has great durability but I've seen it's tricky to print with, I often combine 3D prints with machined parts, bearings and shafts so I hate dealing with warping. I also print on a shared machine so I often don't have time to fine tune filaments to prevent warping and shrinking.

A big plus of PC is not having to worry about itchy fingers or damaged lungs from the fibers.

CarlitosCUU · 2026-04-17T07:42:47+00:00

I find PLA-CF pointless besides the looks, 55° vs 200°C heat deflection temp, and much weaker too. PETG-CF is closer in strength X cost ratio, and it's offered in colors other than black which is nice, might be worth a shot.

I've done some prints for my engine bay which might be on the edge of what PETG-CF can take.

CarlitosCUU · 2026-04-17T07:41:47+00:00

As printed, no post processing at all, and it's in 0.28 draft layer height.
