Got the parts to repair the HD machine today and after replacing the heater (which needed replacing anyways since it's had a loose wire I've had wrapped in electrical tape for over a year) and thermistor (which had broken loose from it's metal casing, undoubted causing my "heater errors"), it now seems to be printing fine, though the X motor was making a very odd low level hum when I first started it up, which is strange, since that has absolutely nothing to do with any of the parts I just replaced.
Sigh.... Probably another component waiting to go out.
On one hand, it's nice that most of the standard-issue parts only cost between $8 to $15 and are usually pretty easy to swap out, but I wish they didn't have to be swapped out quite so often.
For those who are interested, the latest generation of resin printers just coming out on the market are finally catching up with filament printers in terms of build area, making them more useful for customization.
It used to be the Moai printer
was the biggest resin printer on the market at 130 x 130 x 180 mm, but Wanhao (the company who makes my filament printers) recently released the Duplicator 8
which has a 190 x 120 x 180 mm build area, and there are already competitors popping up like the Tianfour Super King Kong
(which I want just for the name) which can do a whopping 200 x 170 x 280 mm (or 7.8" x 6.6" x 11.0")
That's actually a larger total print volume than my HD printer, and big enough to print a full-sized TARDIS or even a Bessie or Whomobile in one go!
The layer resolution is actually slightly less than my HD filament printer (25 microns instead of 20) though the Moai still has them all beat in terms of print quality with an insanely detailed minimum layer height of 5 microns!
Unfortunately, the costs for all three are still pretty steep. The Duplicator 8 will run you about $1100 on sale, while the Maoi costs closer to $1400, or $1700 for the Super King Kong.
Note: The Duplicator 8 is a DLP printer which uses a different voxel based print process, which means up close, it's going to be more pixely
and have more distinct layer lines on it's curved surfaces than true SLA printers. But on the plus side, it's supposed to be faster, pretty user friendly, easy to maintain and replace parts on, and can apparently print using almost any UV resin.
