TCPoly Ice9 filament settings  

RE: TCPoly Ice9 filament settings

I've looked at the stuff and it sounds like it will be usable on the Prusa printers, but I don't have any direct experience with it. I'd start with a TPE profile based on the data sheet and go slow.

RE: TCPoly Ice9 filament settings

thanks for the reply.

Any recommendation of which profile to start from - there is no one TPE do you recommend one?

otherwise I'll start with Flex and see how it goes.

RE: TCPoly Ice9 filament settings

I'd start with SemiFlex or Flexfill 98A and adjust the Max volumetric speed up slowly with testing.

RE: TCPoly Ice9 filament settings

thanks for the hints. 🙂

Hi @ahmed-s6,

Did you have any luck printing TCPoly?  Do you print the rigid or flex?  Also, how do you attach the printed heatsink to the electronic components?

Would be nice to make side by side comparisons with standard aluminium, copper and TCPoly with a heat camera - wish I had one.  

Thanks,

James

RE: TCPoly Ice9 filament settings

sorry for the long absence.... as promised here is an update:

1. I changed the Nozzle of my printer to Olson Ruby so the following settings are for that set up + MMU2S.

2. To make the filament loading work with the MMU I had to change the extruder idle cover to increase the height and depth of  the bit that triggers the filament detector 1mm longer and loosen the tension screw quite a bit so the filament would load properly. Contact me if you want the Fusion360 file or STL.

Loading and unloading this filament is tricky, don't be tempted to use "load to nozzle" with Flex. While it loads ok, trying to unload it is almost impossible without the filament warpping itself around the bondtech gears. Instead I've slowed down the loading and unloading from the slicer profile based on the TPU filament.

Although the manufcaturer recommends a 0.8 or 1.0 mm nozzle my 0.4 seems to work fine but I have not tried a big print yet.

Hi @ahmed-s6,

see previous comment. I have just managed to print this in test heatsink. Seems to work ok. I chose the flexible filament because it would give me some wiggle room to attach components to it, in my case a TO-05 Can. I'm creating a rigid structure for it to sit in using PETG so the heatsink is sandwiched between rigid layers and in the path of the cross airflow from a small fan that would flow over the perforated heatsink.

Hi Admed,

Thanks for your detailed description and offering the STL file, but I'm not going to invest into MMU anytime soon.

Does TCPoly require a heated enclosure? I'm building mine right now. I'm planning to print small gearboxes from Nylon Bridge so a heated enclosure is a must - so I read it.

I want to use TCpoly to cool down the motor while running at high RPM.  Maybe the rigid would be a better option, I could design the motor mount from the TCpoly.

Please attach the picture. I'm curious!

Thanks,

James

If you don't have an MMU the settings will work just fine. I would not invest in an MMU if I had a choice, my heatsinks are integral to the design and there is no way to remove them. 

you don't need a heated enclosure. Having said that you will need an ambient of around 24-30C. I live in California so humidity is not a problem nor is the temp. I have been toying with the idea of a heated enclosure for large prints that can delaminate from the bed, let me know how you get on.

If you can go with the rigid, you should. The biggest problem with the flex is that it does not register well on the Filament sensor in the extruder used by the MMU. It is why I modified it. 

RE: TCPoly Ice9 filament settings

Hi,

Not sure if you're on this forum anymore but I just signed up to ask you this:

Do you have any of that TCpoly filament leftover?  I want to use it for a project but it is discontinued and I can't find it anywhere.

Anyone else reading this:  Same question.

thanks!

RE: TCPoly Ice9 filament settings

Hi Kevin

I have rather a lot of it left, most of the reel in fact. I found an alternative way that was more durable for me so I did not need much of the filament. Let me know if you are interested in buying it.

RE: TCPoly Ice9 filament settings

Yea, I might just be!   I'm not quite finished with my part yet and it's a bit large so Ill have to see how much material it will take (including screwups!) to build.  What was your overall impression of the print quality once you sorted the details out?   My part will be structual but also needs to try to ditch a lot of excess heat continuously.

Also, where are you located?  I'm in Charlotte, NC.  You can reach me directly at [email protected]  thanks!

RE: TCPoly Ice9 filament settings

Also:  did you have both flex & rigid?  I was thinking I'd want to use rigid but I might think of some way to use flex instead.
