# Unique Product Questions 2026
hese 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.
Do we have you link to where someone can purchase a replacement rubber plug filament hole on the polydryer box?
I am sorry but we do not, it’s a custom part.
Do you offer a 5VA rated material that is suitable for use on a bambulab X1C or H2D
We tried several PA6 formulas with 5VA test. Some of them could pass it, but the printability and layer strength of them is not so good. So we have not got one formula with 5VA and good printability at the same time.
We do not currently have a material that can pass this certification.
Can you provide the ratio of PC vs ABS on PC-ABS?
No, we cannot give out formula details
Will HT-PLA stand up to soaking in hot water up to 140F?
HT-PLA *can work* for this application if the parts are annealed and not under mechanical stress during soaking. If the handles will be frequently soaked for extended periods, PETG or ASA would be the safer material choice.
Does TPU95 contain latex?
PolyFlex™ TPU95 does not contain latex. This formula consists solely of pure TPU material.
Do your Fiberon nylons have UV stabilizers?
Fiberon™ PA612-CF does **not include dedicated UV stabilizer packages** in the formulation. The base PA612 polymer itself has **moderate inherent UV resistance**, and the presence of carbon fiber can provide **some degree of UV shielding** by reducing direct UV penetration into the polymer matrix. That said, PA612-CF is **not specifically designed or qualified for long-term, unprotected outdoor UV exposure**, especially in demanding environments such as marine applications where UV, humidity, and salt exposure are combined.
If **long-term, uncoated outdoor exposure** is required, especially in marine environments, **ASA-CF** would be the more conservative material choice.
Can a Stratasys F370 use Polymaker filament?
Stratasys F370 can only take chipped filament that the printer requires to read it. So no, not without modification of some kind to make it a work around.
Their filament diameter is also little bit larger than 1.75mm
The screen on my polydryer will randomly disply odd artifacts or not display the correct information.
You may have a malfunctioning unit so please reach out to with your order information, the serial number of the dryer located under the dock, and a photo of the screen.
That said, generally, there are two possible causes for this issue. The first is strong static electricity; once the static is discharged, powering the machine off and then back on should restore it to normal. The second possibility is that external force may have cracked the screen, resulting in liquid leakage.
Do you have a suggestion for continuous printing across multiple spools outside of an AMS like system? For instance - you can't use brittle filament in an AMS like system but I would like continuous printing so when one spool runs out - it continues printing.
We would suggest checking out [InfinityFlow](https://infinityflow3d.com/)
Do you have any info if any of your TPU options will work for silicone molds? Will EPOXY stick to them?
Our PolyFlex™ TPU series materials exhibit relatively weak direct chemical bonding with epoxy resins. It may require testing to see if it works for your application
Do you have the model used for printing your PETG-ESD results?
We used a simple surface for testing, and you can refer to our TDS to print something similar. For moisture concerns, we recommend using dry filament, as moisture can vaporize during printing and create gaps in the printed parts.
What would you suggest as a replacement for delrin?
Unfilled nylon would be the closest we have to Delrin.
Would an ESD material be good for a project that needs to block RF signals?
For effective shielding performance, excellent conductors are required. Even when printing with ESD materials at high temperatures, they only marginally meet the standards for conductors and are not considered excellent conductors. Although we haven't conducted similar tests, using ESD materials might not be advisable.
Do you have a material we can suggest that can be autoclaved?
Short answer: we don’t have internal validation/certification documented for any Polymaker filament to withstand standard steam‑autoclave cycles (121–134°C).
Do you have a product close to Ultrafuse TPC 45D from BASF?
The closest we would offer would be our TPU90, but it will not be exactly the same.
Is it just general guidance for PolyCast to not be recommended to cast with traditional plaster? Should plaster be avoided in general or is it specific to PolyCast?
Short answer: it’s specific to PolyCast. Because PolyCast’s recommended burnout is 1000–1200°C for 1–2 h, standard gypsum‑plaster investments often crack or require very long cycles—so our guidance is not to recommend plaster for PolyCast.
Do you have a material that meets high mechanical strength, thermal sterilization, and radiolucency?
I would recommand PPS-CF10, but you need at least 320C nozzle to print.
Based on:
PPS composites offer excellent stiffness, dimensional stability, and creep resistance compared to most printable polymers.
Good resistance to repeated **steam sterilization cycles (134°C / 273°F)**
**Carbon fiber** generally produces fewer imaging artifacts compared to glass fiber.
What are the dimensions of your old plastic spools?
These spools are discontinued - but our old plastic spool dimensions were:
200mm Outer Diameter
68mm Spool Width
54.9mm inner core diameter
This is not true for our cardboard spools.
I see you mention you can also anneal PPS-GF20 at 230C for better performance. How long did you anneal at that temperature for?
Also 10h
With heat sets and materials that need to be annealed - do you put the heat sets in before or after annealing the print?
After. Install heat‑set inserts after annealing; for nylons, do it after annealing and any moisture‑conditioning if tight tolerances, since dimensions shift slightly.
Will zircon and water adhere to Polycast? If not, do we offer any materials that will?
Short answer: **yes** – a standard zircon + water investment slurry *should* adhere to PolyCast, and we don’t have another filament that’s clearly better than PolyCast just to solve this.
**If you're seeing poor adhesion, focus on:**
* Making sure the PolyCast surface is **clean and release‑free** (no mold release, oils, or un-rinsed IPA/solvent from smoothing).
* Confirming the zircon/water slurry is within the supplier’s **solids/viscosity window** and using adequate dip dwell time so it fully wets the pattern.
* Avoiding overly aggressive draining/air‑knifing on the first coat and ensuring controlled drying so the shell doesn’t crack or spall.
Is there any difference between the old PolyMax PETG-ESD and the new Fiberon PETG-ESD at all?
Nope! It is exactly the same formula just under new packaging
Do you have flash point, kinematic viscosity, or VOC 9% or g/L) for your materails?
No, we do not have this data at this time.
How do you produce a permanently anti-static plastic part, like Festool does with their hose fittings?
Fiberon ESD materials achieve static dissipative behavior through a **carbon nanotube (CNT) conductive network** distributed throughout the polymer matrix.
Unlike temporary antistatic systems that rely on surface migration additives, the CNT network forms a **permanent conductive pathway embedded within the material structure**.
As a result:
* The electrostatic dissipative performance **does not degrade over time** under normal use conditions.
* The ESD function is **not dependent on humidity absorption or additive migration**.
* Performance remains stable throughout the functional life of the printed part.
The commonly referenced **1–2 year effective lifetime** is therefore **not a limitation of the ESD mechanism itself**, but rather a **conservative recommendation based on the expected service life of PETG parts** under typical environmental and mechanical exposure.
ESD performance may change if the surface becomes coated, contaminated, or mechanically damaged, even though the conductive network inside the material remains intact.
Do you have offgassing information for PETG-ESD post print?
Under normal conditions, PETG-based materials are considered stable well below their glass transition temperature (77 °C for PETG-ESD). At temperatures such as 65 °C, we would not expect significant off-gassing from the printed part during normal use.
However, we do not currently have specific quantitative off-gassing test data for this material at that temperature. If your application has strict requirements (e.g., electronics or PCB environments), we would recommend conducting a small-scale validation test under your actual operating conditions.
Do you have RF data for PET-CF17?
We do not currently have RF information for PET-CF, but you can refer to our PPS-GF parameters to see if they meet your requirements, including dielectric constant and dielectric strength.
Would the same support material that works for PLA also work for PLA-CF?
Theoretically, PLA support is compatible to PLA-CF. Printing defects may be related to the printing parameters of the material and the set environmental temperature.
Was the fan changed on the PolyDryer?
Yes, we changed the fan. Qisu is the old one, and we change it in order to lower the noise and have a better overall quality control, which Kingmot can do. So the latest one- Kingmot is better.
Is there any outgassing data available for Fiberon PA6712-ESD? If there are any TML or CVCM values per ASTM E595 that are available
At this time, we do not have **ASTM E595 outgassing data (TML / CVCM)** available for Fiberon™ PA612-ESD. This type of testing is typically required for aerospace or vacuum applications, and has not yet been conducted for this material.
That said, PA612-based materials generally exhibit **lower moisture absorption and better dimensional stability** compared to many other nylons, but they are still not specifically designed or qualified for low-outgassing or vacuum environments.
If your application requires strict outgassing limits, we would recommend conducting **application-specific testing** on printed parts under your actual conditions.
Do you have solvent compatibility info on PPS-CF?
We haven't do any test but we can provide this chart
Where is PolyLite PLA Metallic Blue?
PolyLite PLA Metallic Blue was rebranded to Panchroma Metallic Blue PLA.
Of the 4 connectors on the front, I know two of them are standard (easy to find) JST connectors, but I was curious about the other 2?
Check the below photos:
Do you have any data for how long after UV exposure on UV shift PLA until the product fully resets back to original color?
No, we don't have this data and I don't think it'll be useful. It is like charging a battery, how strong is the light and how long would affect the results. If we give a data under certain light, we can't guarantee the users use the same light. So for such a application, users test by themselves under their specific using scenario is the best solution I think.
What would you suggest as a good engineering/durable material with little to no creep?
In case the you only want a low creep material, we can recommend PET-CF/GF
For PolySmooth - can you tell me its hermetic seal against moisture, UV resistance and skin safety, and thin coating recommendations?
**1. Hermetic Seal against Moisture:**
Yes, the IPA smoothing process does improve the hermetic seal of the surface.
However, we don't currently have long-term durability data to quantify how effectively this blocks humidity over extended periods.
**2. UV Resistance & Skin Safety:** The UV resistance of PVB (the material in PolySmooth) is typically 1.5-3 years under outdoor conditions.
Regarding skin safety, we unfortunately don't have specific data on prolonged direct skin contact with the smoothed surface.\
**3. Coating Recommendations:** If the IPA smoothing alone is not sufficient as a moisture barrier, we recommend applying a thin coating of either:
* High-quality spray polyurethane (PU) varnish
* Pure acrylic varnish
**Important:** Please ensure any coating you select has skin-contact safety certification.
Please note that these recommendations are based on our technical knowledge and not supported by testing data.
Do you have a suggestion for a hard plastic that will be decently heat resistant (90-100C) that also can work well with mold release products?
If you need a smooth surface, we can recommand PC. If not, or have very high pressue, PPS-CF/GF is better
Will PETG-ESD leave a black mark if paper is rubbed on it? Or leave black powder or contaminant if touched like other ESD materials do?
Yes - PETG base will leave a mark on paper like this due to the nature of PETG. But our PA612-ESD will not.
Does your Wood PLA contain any walnut shells?
No there is no walnut or wood filler at all in our Wood PLA
What is your DUNS number?
DUNS 118960262
I dropped my PolyDryer from a couple of feet off the ground. It works fine aside from screen flickering - is there any worry of internal damage that can start a fire?
A drop from that height is unlikely to pose a fire risk, but the screen flickering suggests possible internal damage; if he notice unusual heat or smells, or have any safety concerns, stop using it immediately and have it checked.
What is the size/info on the bearings used in teh PolyBox?
Roller Bearing Type A (D14 d8 w4)：8*14*4mm\
MR148ZZ
Would the moisture from dissolving PolyDissolve S1 affect the burnout process of PolyCast?
PolyCast may retain a significant amount of moisture internally.
During the burnout process, this moisture may evaporate, which can increase the shell cracking/expansion rate (resulting in greater shell loss).
Possible solutions are:
1\) Dry the pattern to remove moisture before applying the shell
2\) Increase the number of shell layers to improve resistance to internal pressure.
The drying temperature and time is 60℃ and 5 hours respectively.
Why do you not have 3rd party flame retardant tests for PPS-CF and PPS-GF?
There is no standard for 3D printing raw material. We print the same shape specimen as traditional standard and tested it. Here are the results:\
[PPS-CF10 FR Internal Test Report ](https://cdn.shopify.com/s/files/1/0548/7299/7945/files/Fiberon_PPS-CF10_FR_test_report.pdf?v=1777989924)\
[PPS-GF20 FR Internal Test Report](https://cdn.shopify.com/s/files/1/0548/7299/7945/files/Fiberon_PPS-GF20_FR_test_report.pdf?v=1777989924)
Will small amounts of pressure using CF-Nylons cause creep to still be an issue? Do constant heat cycles make it worse?
Quick answers: yes, nylon creeps under sustained load even at low stress. And yes, heat cycles make it significantly worse.
The real question is what nylon property you're counting on — because if it's strength, we have alternatives with near-zero moisture absorption (which is what drives creep in nylon).
PET-CF and PET-GF are good low creep alternatives.
Why is there tape on the end of my Fiberon Spool?
This has been fixed and future production will not have this.
What type of cable can I use to extend the thermocouple cable to display the screen of the PolyDryer further away?
Please note this will void the warranty. But the cable would be: K type plus PH 2.0 female connector
Is your TPU95 Halogen Free?
Yes our TPU95 is Halogen Free
I have an issue where the "M" button is no longer working on my PolyDryer - how can I fix this?
While we stand behind our products and you should reach out to our support email - this can be fixed normally by opening up the PolyDryer and reseating one of the plugs on the control panel:
As mentioned - this should not be required from you though as the customer - this is if you would like to diagnose and fix yourself. Otherwise - reach out to Do you have tips for using a Twin Screw Extruder and grinding PLA filament into pellets?
Panchroma PLA can be recycled and re-extrude into filament. However, we can't guarantee the quality of the re-extruded filament. By quality, printability is the most sensitive one and it will decrease. To recommend, he can blend it with raw PLA pellets.
Recycled raw material will impact the printability of the re-extruded filament. It needs to also be blended with new Raw PLA material.
The recommended temp. is between 190 to 210℃. It is recommended to use lower temp for barrel and die, and to use a higher temp for the adater (between barrel and die). For example,
Barrel Temp: 190℃
Adapter Temp: 210℃
Die Temp: 195℃
However, the temp. is also highly depend on the raw material mix, extrusion speed. So some tests are definitely needed .
We don't have any recommendation for PLA raw material.
Can you confirm PPS-GF20 will maintain all of the mechanical properties reported in the TDS at 60°C?
The mechanical properties reported in our TDS are tested at 23°C per ISO 527/178. At 60°C, PPS-GF20 remains well below its HDT (236°C @ 0.45MPa), so the material maintains structural integrity and rigidity.\
That said, some reduction in tensile strength and flexural modulus is expected at elevated temperatures — this is typical for all thermoplastics. **We do not currently have published high-temperature mechanical data for PPS-GF20.**\
**Recommendation:** For critical applications at 60°C, we suggest conducting validation testing under your actual loading conditions. If you can share more details about the application (load type, duration, safety factor requirements), we can provide more targeted guidance.
Any recommendations for adhesives to bond PET-GF to aluminum?
We have no experience yet but here is our research:
* **CA (cyanoacrylate):** Generally poor adhesion to untreated PET. Not recommended for structural bonding of glass-filled grades.
* **MMA adhesives:** Good for metal-to-metal bonds, but adhesion to PET substrate is limited without surface treatment.
**What we'd suggest:**
1. **Surface treatment is critical.** For reliable structural bonds, pretreat the PET-GF15 surface — plasma or corona treatment works well. Alternatively, a primer designed for low-energy plastics (e.g., 3M 94 Primer) can significantly improve adhesion.
2. **Adhesive type:**
* **Epoxy structural adhesives** (toughened formulations) — best overall strength and environmental resistance. Good for automotive loads.
* **Two-part acrylic structural adhesives** formulated for low-surface-energy plastics — better adhesion to PET than standard MMA.
* **Polyurethane reactive (PUR) hot melts** — worth considering if the joint geometry allows.
3. **For PET-to-aluminum specifically:** A toughened epoxy or acrylic structural adhesive (e.g., 3M DP8005 for LSE plastics, or Loctite EA/H8000 series) with proper surface prep on the PET side.
How does PA612-CF perform below -50°C?
No data, but ancedotally when I visited the testing lab HP Star, they had a PA6-GF25 cryobox print which they would pour liquid nitrogen into. I remember hearing it click and contract as the nitrogen boiled away but after the experiment the part returned to room temperature and didn't have any corner cracks or delamination.
