samantha updated subscribers of T8205: Pluronics profile.

@anolen made some edits to the initial alginate profile, which resulted in the profile attached here. During the print using that profile, she also noted the following possible improvements that has not yet been implemented or tested:
Reduce wall & infill overlap
Reduce speed by 1mm/s
turn travel-combing off

For the record, that machine was one I got from Steven, who told me it was a production unit. I have not made any modifications to it aside from a blower shroud replacement for testing.

regarding ventilation for the furnace - "Venting is encouraged for inside use-- Here in the foundry we have what is essentially equivalent to a bathroom fan for venting purposes. If you are using the unit in a well ventilated area a ventilation system will not be required."

Here is a spreadsheet of necessary items and costing based around Virtual Foundry filament and the furnaces they offer. Note that there are two pages based around 2 different furnace sizes which influences how large of a part we could process.

I have received confirmation from BASF that they see various options for sintering environments, but the catalytic debind has no alternatives for their materials. They did say however that they intend to sell the filament with a deal from their own sintering vendors which you would just mail the printed parts into, instead of expecting people to invest in the equipment and testing.

samantha added a comment to T6691: Sintering kiln or furnace.

According to the BASF Ultrafuse 316LX datasheet I am looking at, sintering can be done in pure hydrogen or vacuum, so we can probably do that with the same furnace in vacuum. The vacuum furnaces that I am seeing are also listed as able to do inert gases. For hydrogen, such a furnace would require additional safeties. I think we should stick with vacuum unless we have need to test gases, just for the sake of not dealing with the gases, but we would have that ability. The BASF material does use a special debind process that also raises concerns due to airborne acids, but in theory could also be done in the same type of furnace. Virtual Foundry materials seem to do a thermal debind that is just contained in part of their sintering cycle, which simplifies things a lot.

While the actuators were extensively tested, and the one wire we saw issues with from the movement of the actuators was replaced with one more robust, the moving wires on the toolhead introduce more fatigue and the actuator is an additional potential failure point that previous machines have not seen in that area, so the toolheads could see an increase in issues compared to other aero toolheads.
