I'm not talking about 'can you play back audio', I'm talking about 'can you play back audio with zero glitches'. This becomes a problem of scheduling precision, whether or not scheduling will 'stall' if a driver hangs while processing an IRQ, whether or not the graphics driver has a potential to hang due to a rendering operation, etc, etc. These are all a reality on modern desktops even if they're fairly rare (I don'…

I am a professional sound recordist for film and I also make electronic music; my office is a studio. I do not consider this a problem for this application . Latency and glitching can become an issue when you're trying to record and monitor in real time while also operating plugins and multiple tracks. That's not the case here. In passing, I'll tell you what is really a problem on current iterations of Windows: MIDI…

I've had good luck with my Focusrite Saffire USB device. Both Windows and Linux. I recall orneriness in older devices...my old Firewire Focusrite had problems. But, it's sad that any MIDI device can possibly have problems anywhere so long after its invention. I have a MIDI interface on a Commodore 64 that works reliably! Likewise, I used to do sequencing on an Amiga...worked fine for MIDI. Multi-track 16 bit audio wa…

Damn I didn't quite realize the ingenuity of using a mirror instead of fixed axis until I read this: >Build volume: There is no certain limit on build volume. In the same way that a flashlight beam gets bigger the further it shines, so does the build volume of the Peachy Printer. Although this has not been tested, we have high hopes to print a full size canoe! This will require a build volume of approximately 3'x3'x1…

I've heard the resin resultant objects are pretty brittle at least on the Form1, so I'm not sure it could do what you're hoping. You would be better served with an FDM printer if you want to be able to use it as you describe, but then you need to be careful of the direction of the grain (or rather, the layers) so that they're opposite the direction of stress if there's specific ways it will take stress.

> pretty brittle at least on the Form1 This is true (at least on the SLA printer I've used). The problem is that the resin never stops UV curing, so it just gets more and more brittle over time. Small parts get really fragile (Maybe you can paint/cover them to avoid this - I'm not sure). FDM or SLS printers are generally better with functional parts, while SLA is better for prototypes that don't need to last.

$40/liter for small prints $45/liter for large Not cheap if you want to print anything larg-ish.

Eh, only if you make the large-ish thing solid - this can easily make hollow / drain-able structures. And since it's partially supported by the liquid as it's built, you don't need as much temporary supporting structure as an extruded plastic version.
