3D printing will be coming of age. And while not a lot will choose printing themselves, print services are already all over the place. So yes, I guess we will (but hey, I must be full of prejudice, my latest build contained a 3D printed adapter plate).
Are there any more that can draw, compared to those who can make things from wood/metal/plaster? Certainly there are those that can take an existing *.stl file and send it to be printed, so little design work involved..
I thought I'd see more using printing as a form/mould than there are simply using prints as is.

With laser engraver getting cheaper, we could be making proper wooden boxes/baffles in minutes at home, dust free. With smoke taken care of it should be safe. I am already using my 10w diode laser for quick baffles mods, speaker grills and other mods, prototypes. One of best tools I bought as a DIY enthusiast. Now I actually use my 3d printer so rarely, only for complex 3d models.
Here are few baffle mods with my laser within few hours including gluing and a speaker grill.

IMO 3d printing is a process with a lot of potential, especially for the future as it becomes more accessible to people (on price and print-size etc). But like any tool it can be used well or otherwise, and I think we aren't often seeing what it will be able to do for us, yet.
For instance there are many examples of people using it to recreate flat and rectangular shapes, that would be better made from boards etc. Rather than taking the opportunity for more interesting and worthwhile forms. In that case it doesn't offer much advantage.
Probably a lot of people just copy existing designs, or even re-use existing files; there seems less interest in understanding things first hand, these days. But I'm sure there'll be more interesting baffle shapes, cabinet shapes, waveguides etc etc becoming common, as time goes on.

The part that struck me most was the DSP and what can be done with it. 😉 According to a video. Measure the output, feed it into software and that will program the DSP to add corrections, Followed by a suggestion that this would be best done when positioned in the room in which it's going to be used. China appears to prefer to sell the automotive version of the DSP but it's still remarkably cheap.
I could find this video making a box using laser in quick time compared to current home 3d printers.
Here are my babies, built with rudimentary tools, a tablesaw, a diy table for this idk how it's called , "milling machine" ?.
painted with roller paint brush , sanded with 150 - 3000 grit, then polished, not perfect, first time I tried wet sanding with so fine grit and polishing.

No different to the old method of EQing to the listening position.
It is not a very good way to make improvements. It's more of a last resort for some, but it can actually make things worse.
Very interested in that ADAU1701 board. a DSP would be awesome for my speakers.
I'm currently using rod elliot's https://sound-au.com/project123.htm , at 159hz x-point. bi amped .

And there is only one way of finding out - try it. Software free and parts not by any means expensive.
I'd guess that results depend on how much correction needs to be done this way even if the do it in the room idea isn't used - just the ordinary methods used to check a speaker out.
The other point is that the initial aim would be perfect xovers etc to give good results.
With 3D printing we can create speakers with even longer pipes and more resonances. No thanks!
I've found a local woman who produces parts with 3D printers. She is busy and has several machines running full time - Lots of ornamental items..
Anyway, planning on getting some bass ports with tapers and flares on both ends to hopefully reduce some noise in my speakers

The acoustic character of the room/speaker interaction doesn't go away with EQ. All you do is ride the wave of the problem and skew the averages. On the other hand if a speaker also needs legitimate EQ, you may see areas of improvement.
The two are easily confused.
Biggest pain in my *** about 3d printer is the print time. Which increases the chances failed prints after all the waiting. With laser I have luxury of trying super fast on waste paper or packing material for a trial and make sure evrything is snug and tight then go ahead with cutting and etching. I wish the 3d printer become that fast 😊
The usual 3D printing filaments are bio degradable so one day your speaker may turn into dust. Bit like similar on supermarket bags when you have used them without problems and suddenly new one start falling apart as they are too old. Other materials can be used but it seems they are trickier to print.
DSP. I'd be inclined to stick to the lowest order filters you can. I assume they are finite response types. On the other hand maybe the software shows what they actually achieve. Things may also have moved on since when I had to look at the things at work. More try and see again really.
