Oliver - an open source ultra precise MSLA 3D printer Hello everyone, The market is being flooded by cheap SLA printers offering better resolution than FFF printers. There's one problem, however. They're not open source! I'm a high school student from Czech Republic and I've decided to change that. I've spent last 18 months developing a custom MSLA 3D printer that's comparable to similarly priced commercial machines (the printer costs roguhly 720 USD). It uses Sharp LS055R1SX03 2K screen, which can be currently found on almost all cheap MSLA machines. This grants precision of 47.25 microns in XY plane. Z axis resolution is 25 microns. I've developed custom board that is connected to Raspberry Pi 3 Model B and also custom 24W LED array with active cooling (2x 40 mm fans). These boards should be manufacturable by almost any PCB vendor, although I've included the exact requirments in the manual. The printer can be controlled by either built-in 3.5" touchscreen (with Tibus interface[1]), or via browser-based NanoDLP interface [2]. The platform have a full 3-dimensional calibration.

Thanks Victor for the information, the old threads are really interesting. I need more chemical know how to understand the matter.

It's a shame how often things like adhesives, silicone tubes and in this case resin become obsolete and useless: one uses 5 drops, and after half a year you can throw away the rest of 300ml because it acted with itself.]]> JoergS5 General New Machines Topics Sun, 01 Sep 2019 09:28:59 -0400 https://reprap.org/forum/read.php?152,858754,858786#msg-858786 Re: Oliver - an open source ultra precise MSLA 3D printer https://reprap.org/forum/read.php?152,858754,858786#msg-858786

The fun thing - while commercial resins have a shelf-life time of maybe 1/4 to 1/2 year, Fernandos resin (stored dark in my basement) was still usable after 2 years !!]]> VDX General New Machines Topics Sun, 01 Sep 2019 06:21:04 -0400 https://reprap.org/forum/read.php?152,858754,858783#msg-858783 Re: Oliver - an open source ultra precise MSLA 3D printer https://reprap.org/forum/read.php?152,858754,858783#msg-858783 JoergS5 General New Machines Topics Sun, 01 Sep 2019 06:16:55 -0400 https://reprap.org/forum/read.php?152,858754,858782#msg-858782 Re: Oliver - an open source ultra precise MSLA 3D printer https://reprap.org/forum/read.php?152,858754,858782#msg-858782
A Duet would be a complete waste of a controller. You only need one axis.... no hotends or heated beds...]]> Dust General New Machines Topics Sun, 01 Sep 2019 06:09:08 -0400 https://reprap.org/forum/read.php?152,858754,858781#msg-858781 Re: Oliver - an open source ultra precise MSLA 3D printer https://reprap.org/forum/read.php?152,858754,858781#msg-858781
I am running my 3D printers with Duet hardware and so I know the firmware best and would prefer to use Duet instead of your controller.

Do you mind if I adapt your printer to this controller? If you have something against it, then I keep my own development to myself. But of course I would like to share it with others if they want to use Duet as well.
Of course I would always honor your development by mentioning where the idea comes from.]]> JoergS5 General New Machines Topics Sun, 01 Sep 2019 05:58:58 -0400 https://reprap.org/forum/read.php?152,858754,858779#msg-858779 Re: Oliver - an open source ultra precise MSLA 3D printer https://reprap.org/forum/read.php?152,858754,858779#msg-858779
I don't know how to produce resin. The only thing I know is that a catalyst is necessary, which reacts to the UV light.]]> JoergS5 General New Machines Topics Sun, 01 Sep 2019 05:10:42 -0400 https://reprap.org/forum/read.php?152,858754,858771#msg-858771 Re: Oliver - an open source ultra precise MSLA 3D printer https://reprap.org/forum/read.php?152,858754,858771#msg-858771 thanks :). Regarding the operating costs, they're indeed higher compared to FFF machine. Resins are just one part and you have to account for all the other things, namely: isopropyl alcohol (depends - if you buy it in small quantity, then you can get as high as 1 USD per print), nitrile gloves - 1 USD per print, safety containers for the IPA + resin solution (prepared to safe disposal according to local laws). Personally, I buy resins from Anycubic (with price of roughly 40 USD/litre). I don't know whether there's a cheaper supplier with reasonable quality. Although I do remember that in January I bought one bottle at 65 USD/litre, so the price is coming down rather quickly.

I have never considered making my own resin, although I do have a question. Do you know about someone who tried to do so? Partly because you've just spurred my interest, but mainly because I'm going to write a sort of school thesis about my work and I have no idea how to describe the chemical composition of photopolymers. And I suspect that resin manufacturers will be very reluctant to share any non-trivial information about this subject.

I have avoided SLA so far because of the high costs of resin. Have you found cheap resin or can you produce it yourself?]]> JoergS5 General New Machines Topics Sat, 31 Aug 2019 15:49:15 -0400 https://reprap.org/forum/read.php?152,858754,858765#msg-858765 Re: Oliver - an open source ultra precise MSLA 3D printer https://reprap.org/forum/read.php?152,858754,858765#msg-858765 thanks for the praise. I appreciate it :). The file is so big because it contains the SD card image and all the CAD files (created in Autodesk Inventor Educational edition - hence I had to publish it under the non-commercial license).]]> Oliver3D General New Machines Topics Sat, 31 Aug 2019 15:09:59 -0400 https://reprap.org/forum/read.php?152,858754,858763#msg-858763 Re: Oliver - an open source ultra precise MSLA 3D printer https://reprap.org/forum/read.php?152,858754,858763#msg-858763
That looks like a very nice printer and potentially an interesting project. I have started to download the big zip (2.7GB) file to look at. Although I am several months (or years) away from finishing my present project I will see if this is to be my next big one.
