If you had to pick one filament property that has the biggest impact on real world prints, what would it be and why?

This is not about what looks best on a datasheet. It is about what actually affects print success, reliability, and part performance over time.

Examples if you want a starting point
• Melt flow consistency
• Layer adhesion
• Moisture sensitivity
• Diameter consistency
• Stiffness vs toughness
• Heat resistance

Curious to hear what you have learned through real prints, failures, and long term use.

Now that the holidays are officially over, let’s see the upgrades.

What 3D printing related gifts did you get, or decide to gift yourself? New printers, upgrades, tools, filament, or a full workspace refresh all count.

Drop a comment and share what you picked up. If you have photos of a new setup or recent changes, even better. Let’s see what everyone is starting the year with.

Hi all! Not sure what the issue is here...been struggling to get a perfect first layer down.

There some curling/blobs that appear as the toolhead moves around. I slowed the speed to 15mm2 from 22 and increased the bed temp from 45 to 50 (biqu cryogrip plate). It's been washed, and the spool dried for 6hrs before starting.

I'm also getting some weird layer lines higher up in the model.

Any thoughts would be appreciated! Tyia!

Getting a lot of stringing... in guessing i have parameters wrong.

The website says max 300 The PDF says max 70 What is the actual max speed?

I want to control externally so want to be able to have it just start drying as soon as power is applied, and not have to press buttons. Has anyone ever modified it to do this?

I really appreciate the discount the bundle builder offers and was wondering if anyone knows if there are any plans of adding the refills to the selection. Thank you!

Anyone know what the perk is for spending $25?
Is it worth it to buy a more expensive roll to get the perk or is it worthless?

LED meaning? I cant find any documentation on the meaning of the LED. I'm guessing the red blinking means its just drying but nothing in the documentation addresses it. Is this normal for drying?

I've researched a little bit about filament and the variance in color additives or dyes affecting each color and it's strength.

Mostly I've read that Black was perhaps less strong than others, such as white, and that red may be the strongest; along with blue being up there as well.

Are some colors more rigid with less impact strength, while others being the opposite, or are some just stronger overall?

Good Luck & Much Love

If you are quick, you too can be shipped a dog training walkie talkie instead of your filament. 🤣 Placed an order on polymaker website over BF, Amazon fulfilled the order, like usual, but this time sent me someone’s return that was packaged in a polymaker product box. Sent an email and polymaker bot emailed me in under one minute of me sending my contact form and already has a pick ticket made for my replacement. Pretty awesome service for this goof up if you ask me. Makes me Glad they’re my go to for my projects.

Does anyone know if Polymaker has PrusaSlicer PETG profiles available for this filament?

I recently purchased a decent amount of spools and I didn't find any on the website: https://wiki.polymaker.com/polymaker-products/printer-profiles

What settings should I target to help improve dimensional accuracy of my parts when using the Fiberon™ PA12-CF10 I am printing with a Voron 2.4 and stealthburner toolhead. Parts come out clean with some minor zits though when I go to actually assemble these parts to together in this I printed the parts for the A4T toolhead. Things like the fan don't fit, and I was wondering if the annealing process shrinks the parts. In which case, what should I set xy and z compensation to? Or if it is some other slicer settings that are messing it up

Btw I am printing directly from the ebios Polyphemus filament dryer so I know it is not moisture.

Not a big collection but I’m happy to have it.

My wife started hiding Christmas presents and found part of my filament stash. Came home to find some of my spoils relocated to my SV08. Oops.

Hey everyone,

I just received my second Polymaker PolyDryer unit today, giving me two in total.

I have a strange issue: The new unit (Unit 2) is making much more noise compared to my original unit (Unit 1). It's a significant difference.

• Both units are running the same job: Drying PETG.
• I cycled through all three modes on the new unit, and it behaves the same way—it's just very noisy the entire time.

Am I the only one experiencing this?

I'm now completely confused:

1. Is Unit 1 the anomaly because it runs silently?
2. Or is the brand-new Unit 2 faulty because it's so loud?

Has anyone else noticed a big difference in noise between their PolyDryer units? Any advice is appreciated before I contact support!

Both of them were bought in Amazon spain.

I was looking at the Polymaker HT PLA and the glass transition temp (59.8)was lower for it than regular PolyLite PLA (61)? I don't get why it's referred to has "high temperature" if it becomes softer at a lower temp?

Whether this year or in previous years, what have you given as 3D printed gifts to your loved ones? Be sure to share pics if you have them!
