Totally paranoia fueled here, but I’m thinking along the lines of extrapolating ‘extraordinary claims require extraordinary evidence’ into the practical applications space of ‘extraordinary material properties that deviate substantially from baseline must have extraordinary compromises elsewhere.’

You know, like the saying, ‘pick any two engineering targets of three: Good, Cheap, Fast’.

The materials are not magic, so why was this not some baseline for all of these years. Why is it when the world is deregulating and accountability for exploitation and criminality are none existent, suddenly some miracle chemistry product comes along?

As stated, this is probably unfounded paranoia and is entirely baseless speculation. However, I think the prudent course as consumers in the present is to be extraordinarily skeptical of all new products. I want to know exactly what additives and base materials are used, what volatile organic compounds these create at all printing temperatures and well beyond. There is poor actual thermal coupling and feedback between a thermistor and the real melt chamber temperature gradient. The thermistor is only measuring a block’s temp with heat dissipation and averaging, not the cartridge temperature or hottest point in the melt zone. So what happens at higher temps than recommendations is important to know especially with high speed printing where the extrusion is pulling most heat out of the block but super inconsistently for PID control loop stability.

I think about Tetraethyllead in gasoline as the standard of chemistry in capitalism. It was the miracle property enhancer solution to stabilize combustion to avoid premature detonation at the cost of harming every human alive.

Whatever is in these products is in the air inside your home. We live in primitive times where biology is only in a precursor stage of discovery and poorly understood. It is not yet an engineering science where humans can wield the power of a complete understanding to create and modify living systems at will. We have never even created life from precursors and reverse engineering a known system.

Until exceptionally transparent disclosure of materials, and testing are provided, (haven’t looked maybe they exist tbh), I’ll stick to older materials that have been somewhat vetted by time and availability with the public as lab rats showing no particularly concerning health issues. For this new stuff, feel free to be the rat in a cage. I’m watching with popcorn ready (sry).
