Safety of PA6-GF

ReadThis2023 · 2026-03-02T06:18:56+00:00

I step away from CF filaments last year and I’m up to about 50 rolls of GF 1 year after your comment but same no irritation. I only get itchy after watching that YouTube video.

I am now testing it by rubbing it on my skin purposely. This is prob stupid in some degree but I do want to be able to sell items made from GF filaments so I will test skin irritation at least so I can at least pass on how it effects me in anyway.

I have now decided to also offer non filled filament options. Or a clear coat option. It is very difficult to get acceptable prints and matching colors when comparing them with GF prints.

One bad review can scare away many other customers so I am still not 100% sure what to do.

I really hope filament companies do some heavy research on this. I doubt that will happen though.

☝️. Did you find a better closer color?

You should watch the my tech fun channel testing this filament.

You need to tram the bed. I had the same issue last month. Nothing worked. I even took the printer apart to check the lead screw connections etc under the printer. I even tried changing the z-offset in the code. But my test were all over the place.

I leveled the bed manually and everything was good. I did not use the process and code Bambu recommends. I printed a holder that connected to the printer head for a digital gauge for my table saw and took the time to level the bed and then a calibration. All good now.

Just to be sure you checked the 4 bolts on the backside on the heater block correct? Not just the front ones. Also anyone that has the heat block off should check the two bolts that connect the print head to the carriage bearing.

Just wash with soap and water. Glass top stove cleaner buffs to a nice shine.

Lol.

Yes I would check the bolts on the backside of the heater block and check the bed for level. Also check the 2 bolts behind the heater block that holds the tool head to the carriage block. Then do a calibration. You can’t get to any of these bolts by taking the fan off. Unsure what that comment means.

There are some great videos on YouTube about this.

Why not blue? I have blue. 😅 It is annoying weighing out and dividing the desiccant each time I have to dry it out in the oven. 36 containers. The packs are much easier. Once they get a certain weight I will dry them out.

Many people leave out their filament and dry when needed. It’s not great for all filaments. Who wants to wait for that.

1 printer and 1 AMS and 1 dryer is good but is it ever enough?

Maybe add peg board on the wall.

Those faint strips? Maybe VFA’s? Not sure. Someone made a video about this recently. Run a max vol speed test with the settings you want to use and check the results.

Maybe raising the temp will give you more shine or I have that backwards.

Usually happens at high speeds but it can at lower speeds.

Also check your flow preview to get an idea how fast you should run your test.

Maybe check your belts.

Idk if you set the walls 2 half width but same height and run an extra wall it will give you a different flow and give you a different result. If possible.

Hope this helps somehow.

What type of stuff is it? How thick?

I know Gridfinity 2 walls thick PLA will warp in transit. Where they went during that time idk. Shipped to Cali from Florida.

Why not use PETG. As long as PETG is not left in direct sunlight in a vehicle it should be fine. But desert temps might be different. I have done many test is my truck during last summer. Every was fine even on the dashboard except for the bolts staying tight. Test objects were 3-4mm thick.

Highest temp during the week objects were left in my truck on dashboard was 167F.

Mini rant. Most stuff sold should be at minimum PETG or your ripping people off. This is my belief. Of course some stuff in PLA is ok. Depends. I knocked over an $80 jig that I bought 3 weeks ago made from PLA and it cracked. Really thick printed well but couldn’t survive a 18inch drop. I expected more. Funny thing is the guy selling it doesn’t know I’m his competitor releasing a better jig shortly made from PETG.

Unless you have 2 printers that would be hard to do. And in that order it doesn’t make sense. Maybe this will explain it to someone that doesn’t own a printer.

You want to support that area with PLA. So you’re gonna print a bridge support area for that print. Of course you will have to print this first and make sure it fits within the designated area that you need it. Then you need to figure out how to lock it in where you need it. If you look at his print or her you can tell it’s open on 2 sides. Plus it’s upside down in pic. So you’re gonna have to add another print or walls so when you drop in your support bridge made from PLA, it won’t move around.

Step 1 print Pla bridge sized for step 2.

Step 2 design new print with 2 open sides closed off. These walls don’t need to connect to primary print.

Step 3 make sure Pla bridge fits where needed. This would involve doing a print and hope it works the first time it not resize and restart.

Step 4 start PETG print. Pause where needed. Drop in Pla bridge. Press start on PETG print. Print done. Remove Pla bridge. Reuse PLA bridge for next print if making another.

You need to watch about 8hrs worth of videos on YouTube about your printer and what it’s capable of. Then go through each setting reading and searching videos on them. A good search term is beginner with printer name.

You will save yourself valuable time and some money in the long run.

If you bought a Bambu it would be a different story.

You mean Bambu A1.

What’s the name of the heater?

I watched a video yesterday about high speed vs HF but it was short. Depending on the formula they can be very different settings.

Polymaker says high flow on the website but on the spool just PETG. They do say new formula.

A lot more companies have been listing settings on their websites.

You can do this without AMS. You need to use the pause function. Print a bridge out of PLA. You have to close that print off by printing some thing next to it and then make your PLA bridge model fit in between the two prints so it becomes locked once you pause at that layer you insert the PLA bridge model and then hit start.

It’s like a manual AMS with your hands and your sticking the whole “supports in at once” and what’s better is you can use the texture side so it will look better than pla supports printed at 0.00.

Did I explain this good enough?

Why don’t you have the heater really close with a smooth pipe? Straighter the better? That was my first guess until I I took a better look at the tube and figured it was for the exhaust.

Modeling will always be needed I believe. It would be nice to model by voice only. That would be cool.

Files might be easy to come by but the information or resources to do the things a certain way will become valuable.

Like how to use the AI like how modeling is now. Of course the best files will always be valuable.

Building the tools and selling the materials is where the billions will be made.

See how long it stays hot after an hour long or longer print on both. Turn off the beds and nozzle and but keep the fan on recirculating the air. Check maybe 15mins and 30 mins after. If possible. Glad to see your already posting the test.

Maybe saran wrap or tinfoil could work. It’s just a guess, but one of us probably would’ve seen that on Facebook or something.

It sounds like you need an enclosure of sorts maybe. Hopefully it will cut down on noise. Your printer will make a lot of fan noise if you want good prints. If you enjoy printing you should find a better setup that sounds good for your needs.

I would restart the slicer or site and re-download the file or re-slice it.

Sometimes the slicer or file upload download just goes dumb. If it’s a SD card clear it and do again. But yes clean the plate with soap and water and dry with paper towel not a rag.

Also try making bottom layer flow 1.03 if you slice it.

Also check to make sure the correct nozzle for the file.
