December 2016 – Page 32 – 3d Printer reviews and information

Hey guys!First off thank you guys so, so much for the response to my initial post on Printy. It really means a lot, with all the other amazing builds out there i didn’t expect the response to be so positive. So, Thank you.Many of you have asked for more details on Printy so i’ll present them to you as best as i can at this time. If you don’t care for this mumbo jumbo wink and just want to see more pictures of the printer and prints then look no further http://ift.tt/2hDaTVS COSTThe number one ask has been about the BOM cost. Right now everything for this DIY printer costs roughly $800. We hope to bring this number down and thus are revising the BOM and trying to finding sources for cheaper components. As an open source platform we want this to succeed and since the number one concern about SLA printing has been about price, this is an important metric for us.How It WorksPrinty is an SLA 3D printer that has a print volume of 100mm x 100mm x 100mm. Its a top down printer which prints by curing resin with a laser beam. The beam is focused on the resin through an acrylic sheet that is at the base of the VAT which contains the resin. The beam is controlled with the use of mirror galvonometers.Printy runs on open source software – currently we use Repetier Host and use Slic3r for slicing. We have built upon the existing marlin firmware and modified it to work in polar coordinates for the laser beam.Currently it takes around 6 hours of build time to construct it and around 30-40mins of calibration.Our AskBased on your interest i want to spend the time and make this printer become a successful open source project.But i can’t do this without your help.So i have one ask – to help me understand what you guys would like to see in Printy. It would suck if i put in the time to write instructions, put together a BOM with sources and put it up and it not being something you guys were looking for and all that work be for naught.What are your pain points with SLA printing? What sucks about it?If you could prioritize only one of the following what would it be? Print Quality? Speed? Price?As i mentioned earlier – our current build time is 6 hours. How do you feel about that?Many of you mentioned affordability – i can’t guarantee i will be able to bring the BOM cost down as it all depends on the various sources i can find that work with the printer. How do you feel about the current price? What would you like to see?I also really want to understand what you guys currently use 3D printing for. Its fun way to learn about what you guys are into and it’ll also help us decide if we should mess with various parameters such as build volume etc for those of you who do larger prints.I am really proud of the design and the way the first few prints are turning out (I haven’t even started optimizing settings yet). I firmly believe in open source (heck, most of my learning experience has been through open source projects) and I really think with a few tweaks this could be the best damn open source DIY SLA desktop printer out there. If you have any input, nows the time to share to influence this project.So i hope you can help me out by participating in this experiment :)On to the fun stuff!!!
