3D printing engineering parts: PLA vs ASA vs PC vs PP vs nylon vs tough resin

My Ender 5 enclosed build is pretty much complete. Finally, I have a range of engineering filaments to test back to back, with the help of Australian F1 in Schools champions Paradoxum. If you can help support them, their GoFundMe page is here: www.gofundme.com/f/support-pa...
The printing of each of these can be refined. The idea is to create data to present to the engineering judges and to narrow down the available options. Fin then takes over in further testing and the team move towards the final product.
Personally, out of these options I was impressed by the ASA and tough resin. They didn't require any special setup to print, which kind of makes my Ender 5 build redundant but I'll still try to improve it.
Thanks to Rod Haas for pointing me towards the PTC heaters and providing support on how to get the best out of them.
Thanks to Adriaan Erasmus for sharing his heated chamber setup with me and also giving advice on how to optimise mine.

Firstly, apologies for the audio quality in the studio shots. Only one lav mic, so I had to use the camera mic instead :/ Seems like a good time to thank my filament sponsor, X3D. They supply me free filament to use in my videos. I receive no commission or monetary compensation for using or promoting their products. I was already a customer before they were a sponsor because in my opinion they sell great quality filament.

I suspect your Nylon was wet. You MUST dry it before printing (and *while* printing, for longer jobs) - you can't just assume that it will be dry straight out of the packaging as it very rarely is, even if it's vacuum sealed with a sachet of dessicant. All of your issues with the Nylon print (maybe except the bed adhesion) are classic signs of damp filament.

[@ovDarkness]

It doesn't look wet on prints - but it's always a good idea to throw it into the oven overnight. I see much more problems with warping due to using improper adhesion interface. Dimafix is ok (when temperature of the bed is over 80C), but I much prefer Magigoo PA. There's caveat though - none of the adhesion interfaces I've tested doesn't work properly with PEI coated beds (and I've tested many material/adhesion combinations). I've had great success with glass and Flashforge print pad as bed. PA6, PA12 and other polyamides stuck very well to it.

[@richardwhitehead6966]

@@ovDarkness Printing Nylon at the moment in a bootleg chamber (cardboard box lined with foil) and having a lot of success printing on PEI using a school water soluble glue stick. 4-6 thin coats allowed to dry between them and the Nylon sticks to it like crazy. So much so that it has slightly damaged my PEI sheet as it contracts slightly when cooling. Best thing is that it cleans up with water and paper towel.

[@automaticprojects]

I find nylon a pain in the ass even when it’s been fully dried and in a fully enclosed heated printer. (Raise3D Pro3)

[@nikaleve1657]

But you can get away with drying and leaving it in a mylar bag for a couple weeks in my experience, at least with Fillamentum FX256 you can.

[@PeterC3400]

All I ever use is Fillamentum's ASA. Never fails, dimensionally accurate, clean, strong. Slight price premium, but not enough to scare me away back to PLA, even for non-engineering prints. Print on heated glass bed with Aquanet Super Hold and it will never ruin a first layer, yet parts often pop off by themselves when the glass cools.

As I said at the end this is just the starting point. Now we put in the time to refine the materials that have shown the most potential.

[@properprinting]

@@TeachingTech Thanks for your answer and nice that you are going to take a further look into these materials! Is Nylon among them?

Boy, I wish I had these kinds of tools available when I was a kid. Plus, another vote for “why no PETG?” It’s going to be stronger than PLA and as easy to print.

[@alejandroperez5368]

PLA is stronger than PETG.

[@rwetmore]

Lol. If you say so...

[@GamesPlayer1337]

@@rwetmore it somewhat is stronger depends on what you mean with strength. PLA is very strong but cant handle impacts very well. If you slowly load it with mass then PLA is very strong. :)

[@rwetmore]

Well, seeing as the context was strength in a part that isn't load-bearing and is somewhat expected to be involved in a crash, I thought the answer was self-obvious, but self-obviously not so. 😉

[@rwetmore]

btw, I've been told by folks enamored of PLA that PET-G is more brittle. Chemically, not true because of glycol's properties, but since many people just leave their partial rolls of PET-G hanging out it takes on a lot of moisture given it's quite hygroscopic. The water breaks down the copolymer chains, and the action of steam leaving the nozzle causes layers to not adhere very well. It's more heat-resistant than PLA and is just about as easy to print. And not much more expensive.

[@truantray]

@@agff1962 ABS is outdated, not stronger than even PLA and throws off toxic gasses.

[@tHaH4x0r]

@@truantray It depends how you define strong. It might have a lower harness (tensile strength), but so do practically all other filaments. ABS is about identical to Nylon and ASA in this respect. Where ABS excels, is at impact strength. ABS has a nearly 8x higher impact strength compared to PETG and PLA, whilst Nylon is only 3x and ASA 6x. Lastly, ABS is very resilient to high temperature compared to other filaments. tldr; ABS is not outdated at all, tensile strength alone does not say a lot about a material, and ABS definitely advantages over other filaments. There is a reason it is used a lot in all industries. I do agree though that both ABS and PETG are missing in this comparison.

🤔 Would orienting the layer layout help on the output (Like how markforged does to lay the fibre throughout the part)? I've made similar parts out of pc and tweaking the layout did yield quite a difference.

[@rexsolomon6325]

There are two kinds of Polycarbonate in the market. One is Makrolon, which is brittle and you can easily test your filament by bending more than 45 degrees - if it breaks, its Makrolon. The other is Lexan which bends and does not break. I am assuming that your PC filament is similar to Makrolon PC, because a pure Lexan will not break on your test. If your bed cannot heat up to 145 degrees C, you will fail to adhere to the bed. Also your nozzle has to get up to 325 degrees. PEI works well at that temperature, but you'll need a detachable PEI steel or thick sheet to remove the object after the print has cooled down.

[@scotthoffmaster4600]

That resin looks interesting, I am testing and using the Flex resin from Monocure because just as you are saying the modells get hard but brittle and as I am using my Anycubic Photon S mainly for printing parts to my FPV Racequad thios would suit my needs. Will that resin only work with Laser or would you be able to use it with a LCDprinter like anycubic?

For my first prints, I've never had so much success on my first shot, which was oversighted by someone with experience in the operation of 3D printers and CNC machines. I found it great to get the job done and build up a little confidence! All in all, it costs with PLA about $1.00 to print parts so failures are acceptable to a point.

I did it on a creality cr-s10 pro, on a creality cr-6 se and on a prusa printer. It sticky very well on the bed, nearly to well. For me, it was as easy to print as PLA, with many advantages of ABS, as higher temperature resistance and UV resistance. More I use it, more I like it.

@@jaistanley PETG density is a lot higher than PLA, one of the highest of any 3D printed plastic. However, the tensile strength is lower (i.e. it flexes and doesnt snap, but does so at lower force than PLA), and the impact strength is practically identical to PLA.

Re: polycarb and BuildTak. Not surprising that PC would fuse to BuildTak, as that surface uses an acrylic component, which is why you cannot clean BuildTak with acetone. A 3D printer company in my area uses BuildTak as their default surface, and when they did a PC print, it permanently fused to the BuildTak, ripping it when they tried to remove it. Re: Nylon. Another local 3D printing company in my area recommends garolite (G10/FR4, basically circuit board material) for nylon prints, and Magigoo markets an adhesion solution specifically for polyamides and which Stefan over at CNC Kitchen uses on his Prusa MK2.5. (Disclaimer: I have yet to mess with nylon; I have a spool of carbon fiber nylon to test with the office MK3 at some point.) I've been having some issues with ABS warping of late, so I'm starting to consider getting a print enclosure heater and some insulation for the office printer...

[@Liberty4Ever]

Watching the video, I was looking forward to suggesting resin printing as the best choice for this part but of course you already had that as your last test sample. You should have excellent dimensional stability and no warping. Not sure what caused that. Similarly, with well designed supports (KZbin videos explaining that, with recommended slicer settings), the support should peel off by hand leaving very tiny surface defects, or no visible defects. In the USA, I buy Siraya Fast resin for US$30 per kg and It's a VERY structural resin. A much thinner wing could be made with less drag and less mass and it would be crash resistant. I just designed an electrical insulator that needed high tensile strength and low weight. The center portion is 6mm x 6mm. I looped paracord through each end. I stepped on one cord loop and pulled up on the other cord with all my strength and could not break this 1.55 gram part.

[@chloemcholoe3280]

all that heating for abs? i honestly put a blanket over my printer(Hypercube evo-s)and the heated bed makes it toasty in there. and i don't even need to water cool stuff. i get warp free big abs prints that way. even on glass with gluestick! it gets super warm there and any pla part melts and softens massively. so even my simple decorative stuff have to be from petg/abs :P

I have good results printing Nylon on glass at 80°C with 3DLAC on my Ender 3 pro with an enclosure. I use supports if necessary and they are hard to remove but not impossible. I hear good things about garolite which I should try.

Garolite is a name brand, the material is phenolic resin.
