Wouldn't have been me. Not having had used one back then, I wouldn't have said anything.
And back then, there was still a lot of ongoing development, particularly around dealing
with printing near and at center. There's been a couple of designs out that had never
solved that problem; Polar 3D did however. So, comments made may have been before the
details had all been proven and people were still skeptical.
[Warning: the rest of this likely will come off as a commercial statement.]
But, actually, they work quite well! (Even better now that they have a print cooling fan.)
However, the point behind them isn't to be the bee's knees of 3D printers but rather to be
a good, reliable printer for education. They have a great footprint to build volume which
educators value: they don't take up much room and you can easily lock them away at night.
They also have fewer moving parts which helps reduce the cost.
All the other things we do with the printer add value to educators but are not unique to
using polar coordinates. What adds value? Well, it's a printer for which educators -- anyone
for that matter -- do not need to install any software to use: no slicers, no printer drivers,
no printer control software, no attached laptop or desktop computer required to drive it.
The printer connects to the "cloud" and from there you load STLs, arrange
the build plate, queue (and manage a queue) of jobs to the printer. The printer pulls the STLs
and slicing configs from the cloud, slices, and then prints. It has a camera which feeds
back to the cloud (as well as time lapse video afterwords). Your print history is in the cloud
so you can repeat prints, tweak settings, etc. Queued jobs can be combined, etc. (Think kids
submitting prints and teachers combining them into one print job.) Oh, and the printer stands
up its own local web interface so if you don't like this cloud stuff, you can ignore it and just
use the local web UI, uploading STLs or gcode you sliced elsewhere. You can even print over USB
if you want or use Repetier hosts' TPC/IP printing protocol. But at the end of the day, it's
a printer which eliminates a lot of the hassles teachers otherwise have to deal with.
Oh, and the way we control our printer can be easily adapted to support others. We have in
the field people driving LulzBot TAZ, Ultimakers, and Printrbots. Again, all from our cloud.
We've not released that yet but when we do, it'll likely be somthing you can buy or just
download the SD card image for and assemble yourself. (I'll be sending one of those units
to Jetguy Real Soon Now.) And no, it's in no way, shape, or form based on Octoprint. As
an aside, our Polar Cloud has been out there for well over 1.5 years,
cloud.polar3d.com.
What's been keeping me busy is version 2.0 of it. (Along with other software projects
at Polar 3D.)
