Unique Product Questions
These questions are very specific but have been asked in the past. These are specifically here as a resource for the AI to crawl to better help you.
Is there any place where we can order swatches?
While we do not currently offer swatches, a third party does seem to make options of our materials. This company is not related to Polymaker, but you can see some of their options for our materials HERE
Was PolyMax™ or PolyLite™ PC called either "PC-Plus" or "PC-Max" in the past?
This name change occurred quite a long time ago, but yes.
PolyMax™ PC was PC-Max PolyLite™ PC was PC-Plus
Do you have any suggestions for a wear resistant material similar to SLS igus' iglidur i3-PL-10000?
While we have not done testing or comparisons, CoPA or PA612-CF15 may be the best options to try.
Can you provide a US location and phone number for any SDS documents?
This is possible but may take us a few business days. Please reach out to [email protected] with the materials you need this for and we will work on creating them.
Previously made SDS documents with a US location: HT-PLA HT-PLA-GF PolyFlex TPU90 PolyFlex TPU95-HF Fiberon™ PETG-ESD
Do you have a UL certification for PC-FR? Can you make one?
I am sorry but PolyMax™ PC-FR (PC-FR) does not have a UL certificate (such as a UL Blue Card), but it has been tested for flame retardancy by SGS (included in the link I sent earlier) using the IEC 60695-11-10:2013/Cor.1:2014 Method B, which is equivalent to the UL 94 standard. The result achieved is V-0 classification, which is the highest rating for flame retardancy in the UL 94 test.
You can find our test results here: https://cdn.shopify.com/s/files/1/0548/7299/7945/files/PolyMax_PC-FR_Flame_Retardant_Report.PDF?v=1641463128
We do not currently have plans for UL certifications.
Is PETG safe around acetone?
The answer comes from the "CHEMICAL RESISTANCE DATA" section of the PolyLite™ PETG Technical Data Sheet. It states that the material has "Poor" resistance to strong acids, with a note explaining that "Poor" means the material becomes unstable upon contact with the chemical at ambient temperature. Acetone, a strong solvent, falls under this category. Thus, PolyLite™ PETG is not safe around acetone, as it will likely degrade or become unstable.
I have seen some people mention their hands get irritated when handling fiber filament printed items. Do you have any recommendations?
Ways to reduce irritation
Post-processing without exposing fibers
Minimize aggressive sanding that cuts into the fibers.
If sanding is necessary, finish with a very fine grit (e.g., 600+) to reduce sharp fiber tips.
Coating recommendations
Epoxy resin (thin layer) → Best for sealing fibers and adding durability.
Polyurethane clear coat (spray-on automotive type) → Easier to apply, good surface sealing.
Acrylic spray clear coat → Light-duty sealing, easiest method but less robust.
All these coatings will create a smooth surface that prevents fiber contact and can improve aesthetics and weather resistance.
Can you over dry CF-Nylon materials? Such as drying them when they are not wet?
Drying CF-Nylon when it's not wet won't hurt it, as long as you stick to the recommended temps and times. The real risk is overheating, not over-drying.
Is creep resistance on PET-CF significantly impacted by the lack of annealing?
There are several ways to improve creep performance:
1. Increase the wall thickness and fill density of the printed part to ensure that the printed surface under stress is printed in the plane direction rather than the Z direction.
2. We strongly recommend annealing, which will effectively improve creep. If annealing is not possible, we recommend setting the load-bearing surface as the printed bottom surface.
3. If deformation cannot be suppressed, we suggest adding a spacer to reduce some of the pressure.
Is it safe to cut PLA with a CO2 laser? Does your material contain any PVC or other materials that should not be cut with a CO2 laser?
Our PLA contains no PVC but it does off gas pretty dramatically. So unless someone has a VERY good ventilation setup, it’s going to be too toxic of an environment.
Long story short, it will cut ok with a CO2 laser, but we wouldn’t suggest it.
My Anycubic ACE Pro is giving filament tangling issues with your Matte PLA, why is this?
This is an issue specific to the ACE Pro setup and specific to Panchroma Matte PLA. We are not sure why this happens and we are investigating this internally. But again, this is specific only to the ACE Pro and Panchroma Matte PLA.
If you do a lot of drying cycles of a CF-Nylon, does the performance of the material degrade?
Repeated drying of CF-Nylons at the right temps shouldn't make it brittle or degrade it. Just make sure to not dry at above the recommended temperature.
Does any carbon fiber nylon material Polymaker produces contain PFAS?
There is no PFAS in any PA-CF formula.
Can I use automotive spot putty thinned with Acetone on Fiberon blends without compromising strength, warpage and temperature resistance?
Use of Automotive Spot Putty (Thinned with Acetone)
Spot putty can generally be used on nylon composites like PA6-GF25 and PA6-CF20, but there are a few key points to consider:
Acetone is not recommended for nylon-based materials. Nylon is partially sensitive to polar solvents like acetone, which can cause surface softening, swelling, or internal stress—especially on semi-crystalline polymers like PA6. This may lead to localized strength loss or stress cracking over time.
Instead, we recommend using epoxy-based or polyester-based fillers without strong solvent thinning, or using a plastic-compatible spot filler designed for automotive bumpers or nylon-based plastics.
Always test any filler or putty on a small section of the part before full application.
Polyester Resin Coating – Risk of Warpage
Your concern about heat from resin curing is absolutely valid:
Many polyester resins are exothermic during curing, with internal temperatures potentially exceeding 80–100°C, depending on volume and ambient conditions.
Since PA6 composites begin to soften above ~100–120°C (though not deforming severely until ~200°C), thin-walled or lightly supported parts could warp during curing, especially if clamped or unevenly supported.
If you want to use a coating approach, here are a few safer options:
Recommended Finishing Options
2K Epoxy Primer or Automotive Filler Primer
These primers offer good adhesion to PA materials (especially with mild sanding or adhesion promoters) and are thermally stable during curing.
Automotive Plastic Adhesion Promoters
Use an adhesion promoter formulated for PA or PP surfaces before applying topcoats or fillers.
Low-exotherm Epoxy Resin Coating
If you want a resin coating, choose a low-exotherm epoxy system designed for composite surface smoothing. Test on a small part first to ensure dimensional stability.
Mechanical Finishing + Paint
For the cleanest result: sand, apply filler primer, re-sand, and finish with automotive paint system designed for plastic body parts.
Summary
Avoid acetone-based spot putty directly on nylon parts
Polyester resin could cause warpage—use with caution or avoid for large/thin parts
Use plastic-compatible fillers, low-exotherm coatings, or primer-filler + paint stack as a safer approach
Do you have materials with biocompatibility?
At this time we do not have a material that has passed the rigorous testing for biocompatibility, but we are working on this.
Why do the PLA products carry a proposition 65 warning for benzene?
This was a judgement from the Product Team. The hypothesis was benzene is a common used ingredient, CA-65 require manufacturer to list at least one material, but we could not test all of our products so the product team decided to list Benzene on the sticker. It doesn't mean our products carry benzene.
We may do further testing in the future to see if we can remove this label.
What is the moisture content of Fiberon™ materials at the time of packaging?
All Fiberon™ filaments are dried and vacuum-sealed to ensure a moisture content of less than 0.3%. Based on our batch-level tests, typical results fall under 0.15%.
Do you dry Fiberon™ filament after water cooling during extrusion?
Yes. All Fiberon™ filaments undergo a dedicated post-extrusion drying process before winding and packaging.
Why does printing ESD materials at higher temperatures drastically reduce resistance?
Higher print temperatures improve the mobility and dispersion of CNTs (carbon nanotubes) in the polymer melt, allowing better network formation. This enhanced connectivity reduces surface resistance, sometimes by multiple orders of magnitude.
Do you have EN71-3 testing for the EU for toys for any products?
As of right now we do not. But this is something we are currently looking into.
What Polymaker filament offers resistance to common paint thinners/solvents?
PPS would be the best option for this, so we would suggest either Fiberon™ PPS-CF10 or Fiberon™ PPS-GF20.
How does the poly dryer work and how come it is the same fan and heater making 3 different power levels?
The adjustment of settings and temperature is mainly achieved through current regulation. The fan speed (RPM) and air volume flowrate are fixed and do not change to adjust the settings. Similarly, the heater power remains constant; however, the overall power consumption varies depending on the target temperature and changes in air temperature, which is mainly caused by current regulation.
Please find below the relevant specifications of the fan.

What material would you suggest that is small like this and creep resistant?
The best option for this would likely be PolyMax™ PC.
Do you have any information about the dissipation factor of the PPS-GF20 material?
We have not tested dissipation factor before.
We've done some checking and we do have small doses of other components in our formulations for improving the printability of the material, and these may cause an elevated dissipation factor, but we don't have specific values to provide. It is recommended that corresponding tests be performed under the parameters of the specific application.
Also we understand that the high crystallinity of PPS helps to reduce the dissipation and dielectric constant, and it is recommended to anneal the material at 130 degrees or 230 degrees before testing.
Also, there are values for dielectric constant in TDS that may help.
I'm planning to use PolyCast filament not for lost-wax casting, but for lost-foam casting — is this possible?
No it wont work, the molten metal is not enough to get rid of the PolyCast pattern.
The foam is easy to burnout and vaporize in contact of molten metal, we think PolyCast is too dense.
Can HT-PLA be used as support material for higher temperature materials?
Yes! HT-PLA has been tested by the community and it does work as great support material for PET-CF. It may work for other high temperature materials as well, but so far only PET-CF has been tested.
Do you have relative permittivity for ABS and ASA?
We are sorry but this is not something we have at this time.
Can you sell empty spools?
I am sorry but we do not offer to sell empty spools at this time. It may be worth checking with our very active Discord community though to see if any members have empty spools they can give away.
There seems to be a line above the plunger seal on my PolyDryer box. Is this normal?
Yes this is normal. That's the injection molding seam.
It is hard to remove entirely especially with transparent material
Does PPS-CF or any other materials require ventilation while annealing?
While good ventilation is required for all materials while printing, annealing should not as the temperature does not go high enough to justify requiring ventilation.
Are your 5KG plastic spools recyclable?
Our 5KG spools are made of PP (polypropylene) and even include some recycled PP. It is recyclable so long as you check with your local recycling facility first.
Does ASA printing produce VOCs?
Yes, normally the smell during ASA printing is stronger than PLA/PETG, because there is more small molecules remained in ASA from polymerization process, which could be thought as the inherent property of ASAWe also recommend checking out this video by Thomas Sanladerer: https://www.youtube.com/watch?v=nofn_MHrxrsAs you can see in that video though - it is recommended to have proper ventilation and filtration regardless of the plastic you are printing with.
Do you have a certificate that TPU90 complies with the essential safety and performance requirements of Regulation (EU) 2017/745 of the European Parliament and of the Council of 5 April 2017 on medical devices?
The tests done on PolyFlex TPU90 are by method of ISO 10993 - 5(Tests for in vitro cytotoxicity), 10(Tests for irritation and skin sensitization), 11(Tests for systemic toxicity), 23(Tests for irritation)All the test reports are attached. Here are some learnings
the iso 10993 is the standard for medical devices (not for material). (EU) 2017/745 is also the standard for medical devices (not for material). In terms of this case, the tests should be finally done on printed insoles which means materials, printers, process of printing, environment of printing, etc are all related with the final result. and the tests should be done by our customer, if their products are regarded as the medical devices which need to follow (EU) 2017/745
The purpose of material companies (like us) to do the test on material is only to enhance the confidence that the final products(like insoles) can pass the test
In general understanding, material can pass ISO-10993 -5/10/11/23 is good for skin contact application
What are the shrinkage rates for our nylons? How much does CoPA or PA6-CF or PA12-CF or PA612-CF or any nylon shrink?
This depends a bit on if you are talking about the part right after it is done printing and annealing, or if you mean after you allow it to get moisture conditioned. Right when you are done annealing the nylon print, it will shrink slightly, but after leaving it out to be moisture conditioned, the part will actually grow a bit as it absorbs moisture.
More data can be found HERE
How do I combine two PolyCast or PolySmooth PVB prints together?
To combine two PolyCast parts: Alcohol (it is a good solvent for PVB, which is dissolved into liquid then bonded through two halves, and then the solvent evaporates into a solid)
What coating or plaster is best to pair with PolyCast for investment casting?
For investment casting with PolyCast filament, the choice of ceramic coating can depend on the type of metal being cast and the desired surface finish. Common options include:
Silica-Based Coatings: Widely used and generally compatible with various metals.
Zircon-Based Coatings: Often preferred for high-temperature applications as they provide better thermal shock resistance.
How Hygroscopic is your Fiberon PPS-CF? How affected by moisture is it? Does PPS-CF require a filament dryer?
PPS-CF has a very slow moisture absorption rate and is not sensitive to moisture. However, moisture adhering to the filament can degrade the appearance of the printed parts. Therefore, we recommend using a PolyBox or PolyDryer to store the filament. If the filament has been exposed to the environment for more than 3 days, we suggest drying it again before use.
Can I print Fiberon PPS-CF at 300 degrees Celsius? Can PPS-CF be printed at a lower temperature?
We’ve set the minimum recommended printing temperature for PPS-CF at 310°C because, although extrusion is possible at 300°C, it can lead to significantly reduced interlayer bonding strength. This would negatively impact the overall performance and user experience.
Will we get Fiberon spools in 1KG? PET-CF, PPS-CF, PA-CF. 1KG spools for Fiberon?
We will not be making any Fiberon 1KG spools in the near future due to the fact that carbon fiber blends are more brittle on the spool and difficult to wind tightly. This means the core on the spool is larger and 1KG of filament will not fit on a 1KG spool.
We do offer 3KG options though for all Fiberon products.
What is PPS-CF10's chemical compatibility in contact with crude oil and aromatic solvents at ~120C for extended periods of time (several months)?
We have optimized the printability of PPS-CF10, making it easier to work with, but the base material remains PPS. PPS inherently possesses good resistance to oil and aromatic hydrocarbons, and we believe these chemical resistance properties will remain unchanged in this blend.
However, due to the specific nature of your application, we recommend conducting some testing to validate the material’s performance before full implementation. This will help ensure that any potential differences arising from switching materials do not adversely affect your results.
Is there a way to seal Carbon Fiber Nylon? This includes PA6-CF PA12-CF PA612-CF. Is there a way to make carbon fiber nylon water tight?
We didn't do rich experience on this, but we found there are several articles on the make parts water tight by using proper printing process.https://all3dp.com/2/watertight-3d-print-tutorial/https://blog.prusa3d.com/watertight-3d-printing-pt1-vases-cups-and-other-open-models_48949/
Is there a UL94 certification for PPS-CF? Is PPS-CF UL94 certified?
There is no UL94 certification for PPS-CF
How does PETG-ESD surface resistivity vs printing temperature work? Does printing temperature affect surface resistivity?
The surface resistivity is related with the nozzle temperature, as the surface resistivity related with
the conductivity of material
the adhesion of shell to shell and layer to layer - less space within the shell to shell and layer to layer help to lower surface resistivity
Therefore using higher nozzle temperature helps lower the surface resistivity.

Whys is the glass transition temperature (Tg) lower than the Heat Deflection Temperature (HDT) for Nylon Materials (or any other material that this is true for)?
The glass transition temperature (Tg) refers to the temperature at which the amorphous regions of the polymer soften. However, HDT is a measure of the material’s ability to bear loads at elevated temperatures, which is more influenced by the crystalline regions and fiber reinforcement. Since the crystallinity increases during annealing, the HDT can surpass Tg as the material remains structurally stable at higher temperatures under load.
Annealing encourages increased crystallinity in the polymer. For PACF, this means the crystalline regions within the material become more organized and dense. These crystalline regions have a higher thermal stability than the amorphous regions, allowing the material to maintain its shape and stiffness at higher temperatures, even above its Tg.
Are the CF Fibers in various filled filaments the same across blends (PA6, PA12, PA612, etc) with only differing amounts of fiber? Or are the fiber lengths themselves different as well?
For PA6-CF, PA12CF and PA612CF, we are using same carbon fiber in production. For PET-CF, the carbon fiber will be shorter because the different process. For PETG-rCF, the Fiber is different and comes from recycled material.
Is PET-CF Chemically Resistant?
The chemical resistance is mainly decided by base material, and PET generally has a good chemical resistance. Check the charts below:

How do our Glow in the Dark Filaments Glow? Does our Glow in the Dark filaments use Zinc or Strontium Aluminate?
In terms of our Panchroma Glow, there is strontium inside but no zinc. For further information, the total noctilucent powder content in filament is 2-2.5 wt%, but we don't know the exactly strontium element content inside.
How are hex codes determined?
Hex code is currently an estimation of the perceived color: we take picture of a same print under the same lighting condition and run each pixel through an algorithm which output the HEX code
How are TD (Transmission Distances) determined?
The TD is measured with the TD-1 on the reference batch
Do any of our filaments have bisphenol a in them? Do any filaments have BPA? Does a certain material use BPA?
Bisphenol A is commonly used to polymerize into PC materials.Products made from polycarbonate can contain the precursor monomer bisphenol A (BPA). But no other product should.
Does any of our filament pass PLA EN 13432 conditions?
As we didn't go deep into this application (packaging), none of our product has been tested by this standard so far.
What is the difference between Panchroma Satin and Panchroma Matte?
Really it is just the finish - Panchroma Satin being less Matte than Panchroma Matte. But when it comes to branding our Panchroma Satin was our PolyTerra PLA + rebranded as Panchroma Satin. So Satin is slightly stronger than Matte - but didn't find it was strong enough to justify the "+" Label - so we are just calling it off the surface finish now
What are the specs of the fan used for PolyDryer, including rpm and air pressure?
The fan speed (RPM) and air volume flowrate are fixed and do not change to adjust the settings. Similarly, the heater power remains constant; however, the overall power consumption varies depending on the target temperature and changes in air temperature, which is mainly caused by current regulation.

Is Panchroma Translucent Natural PLA the same product as PolyLite PLA Natural?
Yes - they are the same product - just under new branding
Does the PolyDryer power supply have a safety listing from Intertek or UL?
Yes! Find those here: UL Test Report GCC Certificate
Can I turn the beep off on the PolyDryer?
This is not something that can be changed - though new units produced after May 2025 can: In the “SETTING” mode, press and hold both the “Pause” and “Decrease” buttons for 5 seconds to enter the buzzer level setting mode. The display will show “bu-01”. Use the “Increase +” or “Decrease −” buttons to adjust the volume. There are 3 volume levels available. After setting the desired volume, press the “Pause” button to save the setting and exit back to the “SETTING” mode.

Will TPU be able to handle as cold as -25℃?
TPU is not recommended for these cold temperatures as it is below the glass transition temperature - making the TPU more hard and brittle.
Is there a way to use the PolyDryer with the PolyBox?
There is a downloadable file you can use here: https://makerworld.com/en/models/1418219-polybox-ii-polydryer-remix?from=search#profileId-1473071
Do you have any data on the compressive strength of ASA or ABS?
We do not have this data at this time.
Is there a way to recharge the UV transition PLA?
The effect will last just a couple of passes unless putting the print under UV for a long time.
Nylon's properties change dramatically depending on if they are printed wet or dry, however, it does not seem to effect the heat deflection temperatures of the material based on your spec sheets. Is this true?
HDT is primarily a function of the polymer's crystalline structure and glass transition temperature, which are not significantly affected by absorbed moisture.
While moisture reduces tensile strength and modulus, the softening point under a given load (which HDT measures) remains relatively stable because it depends on the thermal transition of the base polymer and fiber reinforcement, not on small changes in the amorphous regions.
That being said, long-term thermal aging in humid environments can still accelerate degradation of properties, even if HDT under short-term testing remains similar.
So in short:
Although the HDT of PA6-CF is largely unaffected by wet vs. dry state, this does not mean performance under heat and load will be identical in real-world conditions, because creep resistance and dimensional stability may still decline with moisture.
If your application involves continuous exposure to high temperature and humidity, we recommend:
✔ Printing with dry filament
✔ Annealing after printing to improve crystallinity and dimensional stability
✔ Considering PET-CF or PPS-CF for superior hydrolytic stability if moisture resistance is critical
