LOL, thank you for the giggle this evening, Mark. smile

Actually I meant raw as in sheet, or rod that you can mill to specs not everything needs to be or can be printed. There are other forms of manufacturing that sometimes are better than printing.

We need the exact temp the material would be exposed to for the greatest time. That is what would determine the optimal material if any.

I did a simple 2:8 ratio and 8:2 ratio on efficency : thermal loss

so using 20% as the basis of efficiency, the output of 80% heat is 240 Watts
and using 80% efficiency with 20% thermal heat is 60 Watts

the item in question is going to be thermally balanced so that its initial draw will be high but its maintaining draw would be the lower end of the scale. or in simple terms, 240 Watts to get up to temperature and 60 Watts to maintain temperature in a thermally balanced system that has active cooling to help maintain the balance.

Hope that helps.

I understand that - but the lack of information is also making it difficult to offer "accurate" suggestions.

for me, if it is load bearing, and subject to some heat, then I would go with one of the nylon offerings. It would be far more durable than PETG.

just a suggestion, however. You do what you want.

but not knowing the exact application, it is just a suggestion.

But if it is load bearing it could be an issue as it softens from the heat, the load will make it deform.

I am figuring that there is a fair bit of heat given off with this item, so I was asking based on experience the best material that is out there that can withstand around 60 degrees celsius. There will be fans to help with thermal dissipation.

It is the only material I print with now. As for the glass transition temp it is around 80c so it may not be high enough for you.

PC would be the best i believe. Nylon, ASA, ABS depending on the temps it needs to withstand
