I use a large PP Foam box (the black ones used by food delivery services aka Pizza boxes). It can withstand 120°C and offers very good insulation. My heat source are 2 300 Watt PTC Elements, each with its own all metal fan. Controlling is done by an Arduino running custom code and utilizing a industrial temperature/humidity combo sensor. Over all build cost ~300 Euro, but i can dry 4 3Kg Spools at once and heats up very quickly + you make up for its cost rather quickly in saved energy compared to the mostly not at all insulated stuff used in the 3D printing space (like food dryers or even the sunlu dryers).
Sounds like an efficient solution, but why did it cost so much? Was it the industrial sensors or the cost of the insulation material? PTC heaters and microcontrollers should amount to about $50. SHT71 are very accurate temp/humidity sensors and cost $5. So theoretically this project should be doable with a budget of under $100.
I was about to recommend the micro swiss CM2 after using it, but you beat me to it. I am really impressed with whatever coating they went with, ABS just wipes away like nothing I have seen before, literally one swipe with an old rag and it was 100% clean again. Filament also seems to flow better so you don't get the hooking effect soon as it exits nozzle while under high pressure. This is the first nozzle I have raved about...
I used a product with was a PC CPE CF blend which is similar to this. I found the drybox preheating the material was also a factor. (so consider that if you get your drybox sorted out in the future). These materials are ballers man! I actually made machining fixtures for a customer from it. That's how strong they are! Enjoy and thanks for the great video!
The filament seems interesting, but it does NOT seem like a replacement for PC. When I think about PC (not PC blends), I think of heat deflection temps of ~135C and high impact strength. The HDT of this isn't directly comparable to the PC I use (3DXTech) due to the differences in testing methodology you mentioned, and they don't cite an impact strength on their data sheet (but PETG is generally quite poor with respect to impact strength). When it comes to drying filament, I have a heated chamber printer (which is the only way to print larger PC pieces at high infill), so I can dry in that, but I also use a NuWave Brio 15.5 qt air fryer, and IIRC the inside will fit about a 10.5" spool (and air fryers are also really handy for regenerating silica desiccant and annealing prints). Also for spools I use a cheapo lazy susan with a 50mm tube glued in the center (so the spool is horizontal). Filaments are stored above the printer in plastic boxes advertised as 'water proof' (not really but they have weather striping) with a tub of silica desiccant.
Some good tips there thanks! I use Home Depo's white buckets that come with air-tight seals to store the spools. Each one holds 5. I toss a silica bag in each one (aquarium filter media bags with zippers so I can empty it to dry it & fill back up)
At the end of the video I was left with the question: "So, what the heck is it?" because it's not comparable to PC to me. I'm looking for my next baby step up from all the ASA I print and besides real/pure PC I'm not sure there is anything better without going to crazy engineering grade stuff that I need to modify my hotend and bed to print.
@@mjodr Polyamide PA6 + CF might be a good choice ^ Doesn't need anything special to print it (I think it even sticks to cold beds) and super strong from what I gather
I often use tough PC by inland from Microcenter. It's one of the easiest filaments I've used with great layer adhesion. It definitely requires an enclosure.
I pre dry my filament in a pesto food dehydrator with the center grates cut out. I feel like the heated spool holder filament dryers don't dry filament they just keep it dry. You can get any sized spool into the food dehydrator you just need enough rings/grates.
I dry my filament as well in a food dehydrator, but I bend a aluminum sheet in the circular form and do not need any grates anymore. Very easy ans cheap
its a great material prints on a bambu X1C with the bambu PC material settings and PETG/ASA print speeds settings. 100m/s to 60m/s. has good wear resistance so I've printed gears with it and they have held up well.
For functional parts and when great layer adhesion is neccesary I prefer PCTG. And you could print it much faster than PETG. Layer width of 0.6mm with a 0.4mm nozzle is no problem even on high speed printing.
I've been using PETG+ lately for anything load bearing. It does need some drying but otherwise prints as well as non silk PLA and it's very strong and resilient. Supposedly it's blended with polycarbonate. Plenty strong enough for my latest design for a flex drive outboard motor.
Thanks for introducing this new filament. Sounds very interesting. I would like to know more about the creep performance, layer adhesion and resistance to warping on large prints?
I buy 5kg spools when available, but on filaments that need drying I typically dont dry on the original spool. I respool them onto steel 1kg spools instead. I usually do the typical 4hrs@90c in a repurposed food dehydrator.
Eibos Cyclopes can fit up to a 3kg roll of filament. I have never personally done so, but that's what it says on the tin and it should be able to hit good high temps for drying that filament.
I'm interested in layer adhesion, if it adresses those problems but introduces stringing, that might be a hidden gift 😅 PC is amazing, but with zero part cooling, 45mm/s print speed (volcano nozzle) and 0.12mm hieght that normally make mold like parts.. PC still splits at the layers when i test break parts (Black PC). Side thought; i never tried white PC which is colored with oxidized titanium powder that tends to improve thermal conductivity and thus layer adhesion. Opposite of carbon that is added to make the filament black 🤔
IC3D is where I have got all my filament since I entered the hobby. I have never had a clogged nozzle or any print failure due to the filament. I know I could get cheaper filament, but I just want to print without dealing with drama.
I’ve had my eye on high temp filaments for heat ducting for a diesel heater project for a while. Figured I’d use either a PC blend or PCTG filament so this may be in the running.
A printer with enclosure should be able to print comparable PC (blend?) filaments. Maybe you could try the PC from two years back and test it with current printer? 290/110 does not sound "print simple like PETG" ;) Deflection temperature and drooping aside, is it even close to PLA or PLA+?
I'm a PETG-main, and I want to dip my toes into engineering filament. I had some good results with Matterhackers Ryno (albeit, with major over-retraction issues before tuning). If I run a retraction tower, temp tower, and flow test (hollow box, comparing printed wall width to slicer), is there any other test I should throw into my "New Filament Testing/Tuning" lineup before committing to a project with said filament?
Thanks! great vid. Is Polyhex UV resistant? Which of these UV resistant filaments > ASA, PCTG & PETG are 'strongest'? Speaking of those which UV resistant filament would you recommend for functional parts... eg a shed door handle?
I typically print with 5 kg spools of polymaker asa, there are no commercial filament dryers to accommodate such large spools so I was forced to build my own out of a food dehydrator.
I have designed a device that is used in the boating industry, picture a bracket for deploying a trolling motor…. What filament do you recommend for high strength and high UV resistance, along with low water absorption and low shrinkage?
Shrinkage is just half percent less than ABS, heat deflection temperature also similar (Polymaker ABS). It may be better for chemical resistance but what about stiffness? if it's a copolyester it may be quite less stiff than ABS. Is it really competing with PC? it seems a competitor to ABS, since very few ABS are as stiff and as heat tolerant as Polymaker, and this one would end up being equivalent or better in every way (and more expensive). What about humidity? is it as sensitive as PETG and other copolyesters are? this would be a BIG downside vs high quality (Polymaker) ABS. Stringiness may be caused by that: once I dry PETG very well, stringing is mostly nonexistent (Fiberlogy PETG).
"Is it really competing with PC?" - No "it seems a competitor to ABS" - yes, closer. ABS/ASA..but with all the stickiness and stringiness problems that made me throw my PETG spool out the window
I am making a basher RC car. I wonder if this stuff would work for its strength capability? I am using regular PETG for now. Haven't tested it yet because still printing stuff...
It’s been on my list for a while. The one I have been watching has evolved a few times but I think it’s in a really good place now. How hot do you think it gets in the engine bay worst case scenario??
@@ModBotArmy idk maybe 150-200c if you had a turbocharger and not a lot of air movement?? I’ll do some testing next time we go Jeepin’ to see what underhood temps look like in our “worst case” scenario.
Yah, that was my first thought too. I looked at the data sheets for both and they're extremely similar. There are some differences in the suggested printing settings/environment but the mechanical properties of the resulting parts are supposed to be nearly identical. Overall it looks like the PolyHex is cheaper whereas the CPE-HT is supposed to be a little bit easier to print. Not sure how much of a difference there actually is in practice.
I’m looking to make boat fittings out of long strand carbon fiber and epoxy, like cleats, clew stays and blocks. Maybe…just maybe deck hinges and hatch latches as well. This might be just the thing to print moulds from!
I've never seen a printed drone prop stay together for more than a few seconds. Have you ever blackbox logged your RPM's or turned them on in the OSD/end flight stats? I would reconsider.
Does this filament require fume extraction or is it relatively safe to print like PLA and PETG? Edit: it doesn't look like an SDS is published yet which is something of a non-starter for me unfortunately.
"Objects printed with PolyHex will have the same strength, rigidity, durability, and chemical resistance of legacy polycarbonate without the typical PC troubles of warping, smell, BPA exposure, degradation caused by moisture, high printing chamber temperature, and cost" maybe not, but probably still have a certain amount. I personally have a fully enclosed printer with a recirculating internal HEPA filter with a carbon basket in front of it. And always leave the printer on and filter running for 10+ minutes after each print with ABS or PC
The slight stringiness, the slight stickiness, the drying, the really good adhesion, it even looks a lot like PETG with the glossy/reflective surface. ABS smells and is warp prone but I hardly have stringing/sticking to nozzle issues and have never ran into issues caused by moisture even when opened for months.
Was a little disappointed with the "high temp". 90°C isn't even close to what PC, PA, or PET can take. It maybe interesting for things that don't need to stand up to an autoclave.
40 bucks for a kilo, not bad for a material that tries to combine aspects of PC and PETG. Not feeling great about the waste/recycling problem, but that seems to come with the territory...
You recommend drying it and claim it will print better when dried, but don't test that theory? Why not test it out while dried and printed from a dryer?
I dried it initially using the printers bed heated at 70c for a couple of hours. It’s a less than ideal method of drying but what I was limited to due to spool size. With it being a copolyester the dryer the better. It wasn’t wet enough to cause any steaming or popping which I have experienced with very wet petg but stringing definitely happens more on wet filaments.
@@RobertCowanDIY I have 3. This is a massive 2.5kg spool. It doesn’t fit in even my largest due to its size. Even the cyclops which is a larger dryer was too small.
@@RobertCowanDIY I really wish they had sent a standard sized spool. It does print well though. Don’t use a brass nozzle and keep it in active dryer the whole time would be my recommendation. Do you have a project in mind for it? I actually just saw you video on the XL flex membrane.
If I have a weird filament that doesn't fit in my box, I slap something together out of cardboard, and use the heating element from a food dehydrator.

Good question. Similar to what I was wondering.
