Very nice. I'm looking forward to it. And thanks for your priceless content.

Igor Gaspar

Yes, all those filaments mentioned in the video. But I have 8 other brands too, already here and I even started with some testing.

Peter Danner

Are you still planning on testing the Fiberon PAs and the PPS Filaments?

Carmelo Locurto

I'm curious who makes that if you don't mind sharing

J F

OH i came across some "American MADE PET-CF" by accident i think i can get you a roll to see how it compares?

Igor Gaspar

I have some, as mentioned here: https://www.youtube.com/watch?v=py33Ak4XuuI

Jordan Berg

Id love to see more PA6/12 videos, its interesting to see how much they vary. It seems I may be using PET-CF for my car parts because of price and consistency. Have you thought about trying matterhackers PA filaments?

I've fooled around with petg rcf for a week or so now and I'm super impressed. Compared to PETG, it prints like PLA and feels super rigid. Just a little weak in terms of heat deflection but otherwise awesome.

I would like to see the material properties normalized for volume and weight, so that this can be compared. In some applications (rc plains, robots, ...) the weight is more important. It would be very helpful, if you could add to the print parameters the bed type, bed temp and chamber temp. With some filaments bed adhesion and warping are the two most frustrating things to have to deal with. - Edit: I shortened my post, because I realized, your Excel table contains a lot of information I just need to read.

Jose Angel Fernández

Just try it for myself. Bed adhesion is brutal, and between layers. Semi-flexible, rough surface finish

Keith Kessler

I'm sorry, hope you feel better soon!

Mya

Hope you feel better soon!

Igor Gaspar

I started, but I got the flu in the meantime. So there will be a delay.

Mya

Looking forward to the pa-cf videos!

Also I see this PBT (https://www.amazon.es/CC3D-Material-impresi%C3%B3n-filamento-PBT/dp/B0CHW5NJ94/ref=sr_1_5?__mk_es_ES=%C3%85M%C3%85%C5%BD%C3%95%C3%91&crid=10R3HR3RV5XI2&dib=eyJ2IjoiMSJ9.UI5Jexf82H_l9Nkdk66r-BAiqzyT0Ma0caJucFe9JnBeL9Uqt9FOy4wNFtAXtIYgm9DW-xhoIKr_tr7PBpXh3ruiCX507BoVNRcComL3yDOqPOvPDBlJGRjavrOoYlNunBEFCOtMpa_dNa6OlyiUtu0fNPJvR6Q-C18YcbjiWIUuJArGZSziUTawjRrDtTArakpdvKHPedmjtzwVjnvx3aFVKfpXRmevTa0LUplG9HAmEnAVDchGunfkyJT1jRAZYowK6sptv0aZRsotfMNxL1lzmb0pUKhDYsbckzATzI444bj5deigBNlB8H-y3fQZUqiE0Ro0F4lFfDIAF2PA-VgcEzTSUwjT02wMROHMBjZp4YJ7QUjDIWxfOUv-SkvnjIhsMsfJ7eoCGnfZxd_0PYagvrNC5-EMuS0FSqwp6ON6x7xlhIKof-RwikeFFjLd.eJRijB_kTKDRsaTxkJl9ieKBUUnrDh2iIbwrZeyjnTI&dib_tag=se&keywords=cc3d+pbt+filamento&qid=1739188554&sprefix=cc3d+pbt+filament%2Caps%2C68&sr=8-5#customerReviews) fiber reinforced filament that another user coments and looks very nice and the price (21eur/kg) is astonishing. I think a review will be very interesting

Jose Angel Fernández

Good work Igor. As a suggestion, I think it would be very interesting to design a way to assess warping in some way. There are some filaments (e.g., a specific type of nylon I have in mind) where the warping is so severe that its practical use is greatly reduced.

I need to get more sleep! Thank you soo much for everything you do. you are my actual only patreon because your efforts provide TRUE value on so many levels thank you for the reference and the hard work. Best wishes and wellness to you and your family!

Igor Gaspar

I already tested Siraya PET-CF. https://www.youtube.com/watch?v=Y7npttLpcO0 And soon Phaetus, then 5xPET-CF (Bambu, Polymaker, Siraya, Qidi and Phaetus)

Igor Gaspar

Not yet

J F

additionally if you need a spool of SirayaTech PET-CF that would be interesting as well as i BELIEVE its the CHEAPEST PET-CF based on its amazon US pricing.

Shane Delmore

Is there a discord server for MyTechFun viewers?

J F

i have been curious about a new stat....Abrasion. i mean i know most of us are using SS or Tungsten nozzles but im still just curious because a LOT of AMS solutions are coming...and these PPAs and PET CFs are considered *too abrasive for AMS* at least for bambu. but it would be interesting to figure out a metric on its actual effects on wear on components. Side note: conductivity test for the various conductive filaments...

sugarballls

I'll be honest, super non-technical answer is used my Levoit PUR131 air filter in the same room. Air Quality stated "Very Good" and didnt change to Yellow/Red. Per my air filter manual Blue = Very good air Green = good yellow = moderate red = bad

Igor Gaspar

How do you measure VOC? I have AirGradient One, but I can't measure any difference printing or non-printing air.

sugarballls

Unfortunately haven't tried PETG-RCF yet

Shane Delmore

I would love to see chamber temp tested. I feel when I print abs and asa at 80C they come out much stronger than when I print at 60C but haven't tried to quantify it.

cold

if you've tried it, how would you compare petg rcf-08 to it?

Shane Delmore

I want to see bricklayers tested using superslicer to reduce the wall spacing so he can get the appropriate wall squish without increasing extrusion for a more apples to apples comparison.

Shane Delmore

I'm a huge fan of pet-cf as well, will be fun to see more testing of it.

I recently went through a whole 500g roll of PET-CF17. I have a Bambu A1, using G11 bed plate. 300c, 80c bed 0.95 flow, 0.030 PA. Printed in very cold room 18-19c average. Very smooth surface finish, layer lines blend like butter. 0 stringing. 0 clogs. Very little to no VOC off-gas ( compared to New Fiberon PA6-CF20 smells horribly). Did 4 random diameter checks with my Mitutoyo, all checked at 1.74 - 1.76. Printed directly out of Polydryer box I have not annealed. I simply just left the part in the open. One of the easiest engineering filaments you could call it i've printed on my A1. Happy to answer any questions. 10/10 would buy again

Kwiatens

You could check how the PET-CF behaves when printed with "BrickLayers" :p Maybe the carbon fibers improve some parameters when printed in such a way (probably not?)

Igor Gaspar

Thank you. Where can I get these kind of information too? I want to know about these kind of things :-) (factory info) The cooling is very minimal already in enclosure. But I will test the printability on open air.

Igor Gaspar

I just got the message from Polymaker (they saw the video). They have big focus on printability, it can be printed on wide temperature and speed range, but their mechanical properties are sacrifised a little bit. I am not sure, how can I test this properly.

Igor Gaspar

Oh, it's almost a topics for a separate video. I am planning to do something like that, but first with ASA (temperature + cooling and maybe chamber temperature)

Tom Dakin

Impact resistance and layer adhesion are two very important factors for my choice of materials. My parts tend to get knocked around pretty hard.

Adam Cagle

Would it be to much to test the difference in strength of different nozzle and chamber temperatures and also how hot you can print it until there is a loss of strength or filament breakdown. I know the manufacturer has a standard for temp printed on each spool but it would be interesting to see what happenes if you keep increasing the temp of the nozzle and chamber until there is a measured deficit. I would test this personally but I don't have proper testing equipment.

Jack Wilson

Awesome, thank you Igor for the hard work. I am very excited about the pet-cf video, it has become my new standard for engineering style prints. I have been printing mine in 55 degree enclosure in hopes that it will further increase layer adhesion. It would be nice to know if it does help or if I am wasting time and energy with the heating process. I would also be interested in annealing. Right now I have been using mostly fiberon pet-cf17, but I have wanted to switch to siraya tech for 1kg spools and slightly cheaper per kg. I'm curios how it compares to the fiberon.

Markus Desel

Pheatus and Qidi come from the same factory iirc. Maybe two step process pet-cf from Luke's lab would be another choice, it uses high quality luvocom resin and 10% fiber content. Pet-cf is perfectly printable in open air, tho cooling should be reduced. Annealing depends on brand. For pheatus I usually print open air at 320C and anneal salt packed at 150C. 200C would yield the highest crystallinity, but hydrolysis becomes an issue and might require an vacuum oven. Higher temps = better heat resistance and higher stiffness but stiffness comes with brittleness.

Léonard Leder

If it was up to me, I'd focus on heat resistance and have different annealing methods compared. But for the other test no need for different annealing. I'm going to do my own test, I annealed at 110° for 7 hours
