What are the next major 3d printing developments?

I hope we'll see clay printers/slicers which build a mold-negative of the parts we want. That way we skip the step of printing a lost-PLA part.
Wouldn't that be easily done in whatever CAD program was used to create the model?

Assuming we are talking about consumer or hobbyist machines, then IMO no major developments will have much effect until we move away from what is essentially a robot controlled hot melt glue gun. While we are stuck with that, we are stuck with printing at the speed that which some mushrooms can grow. There has to be a better way................
I use Shapeways to make certain part for me.
Are you familiar with their printers that use an approach similar to resin printers but using a powder instead of a liquid?
Can you envision those ever being affordable at the hobby level?
Thanks.

@fcwilt I use jawstec for MJf printing certain things, but I would kill for a home version of the technology.
Maybe if I win the lottery I’ll splurge and get a 600k MJF setup

I don't know what either of those things are.
Please elaborate.

@fcwilt jawstec is a similar printing company like shapeways. Both use Multijet Fusion technology from HP (powdered nylon) to print. It’s shortened to MJF. It’s similar to SLS in that regard. It’s supposed advantage is the material strength is equal in all axis, vs SLS is technically weaker in the z axis vs x and y. Same or better accuracy.

@blacksheep99 Yes, the Stratasys heated build chamber patent with external motion system is the main one that expired, finally after a 1 year extension.

Thanks. I didn't recognize MJF but I have had parts printed with it.
Shapeways seems to have another printer that does something similar, as their "Versatile Plastic" was the first type I used and the parts appear much the same as the MJF parts.

@fcwilt Yeah, their "versatile plastic" is SLS - very good. I've had them make some parts for me with that had to be larger than the limits of MJF, and that required the other process.

There are a bunch of Powder SLS DIY machines, but the process is messy and wasteful.

@oliof
...who needs multitool FDM printers when you can fuse a whole layer at once
I've seen a video, where a guy in full_body_suit removed the excessive powder. YUCK
Not my style of DIY printer -
@o_lampe As I said, messy. The wastefulness seems to be a thing of the past, some manufacturers now make powder where they promise 100% re-usability.
