Hi, its alive!, after starting out with the topic of resin printing 3 years ago, and after purchasing an off-the-shelve dlp resin printer i've finaly took the plunge and build my own dlp resin printer. and it works and the improvements and redesigns are an ongoing topic in my mind ) so what did I make here are the specs: Z-axis: Belt driven 450mm planary stepper motor to provide enough torqueby hp_ - Polymer Working Group
Hi Everyone, I am happy to announce that we are now also offering SubFlex flexible resin on our webshop. Subflex resin compaired with SubG+ is much more flexible after curing. 500mL Subflex = 30 Euro 1000mL Subflex = 55 Euro. please have a look at: http://www.2engineers.com/shop/resin-subflex/ Kind regards, hp_by hp_ - For Sale
Hi andin, NewPerfection, Thanks for your info, i've never made those calculations what i did was just put in the motor and test hours on hours.. if your interested checkout this youtube clip http://www.youtube.com/watch?v=NYF8tm0hxXo running pretty good speeds cheers, hpby hp_ - For Sale
Hi, the direct link to the motors have changed to: http://www.2engineers.com/shop/geared150/ be-aware, the 45mm/sec in the configuration file is a suggested configuration. where the max_feedrate is set to 45 mm/sec was working pretty well for me, the thing to take notice of is the acceleration and E_JERK. with these geared motors you have to reduce the acceleration. cheers, hp_by hp_ - For Sale
Hello, It is my pleasure to announce that from now on we are reselling Makerjuice Resin in Europe. The resin can be purchased in all kind of colors or no color at all. The resolution that you can get with a SLA machine outperformce the normal FDM printer by far. We sell the resin in 2 quantities: 500mL for 25 Euro 1000mL for 45 Euro.

Hi Cozmicray, A glass nozzle would work for sure, i'd love to try it out but for now we have made an all 100% ceramic hotend using zirconia, see here a youtube clip where we are printing polycarbonate. Polycarbonate printing at temperatures > 300C as you can see only using an fan from the side of the printer. Cheers, hpby hp_ - Plastic Extruder Working Group
Hi A2, i have no problem printing polycarbonate with zirconia, I haven't tried Nylon yet. hpby hp_ - Polymer Working Group
Hi A2, thanks, we try to keep bussy with good stuff the 3.0mm version barrel ID is ~3.3mm polished. hpby hp_ - Polymer Working Group
Hi A2, This is a real part not a render i have more pictures if you like to see: on this print you cannot see the layers. for your next question about cost, Do you mean operational cost: you don't need that much heat, and you only have a Z-axis motor Printing cost: resin prices are coming down fast. i must say i don't use to much supports as with FDM and that is also a good thing. We hopby hp_ - Polymer Working Group
Hi Everyone, Now that I am using DLP resin printing more and more its clear that the possibilities are huge. Imagen a very complex object that you want to print but you don't have to think about retraction, travel spreed, perimeter speed, temperature hotend, temperature heatbed.. etc etc.. you just need to think about load image, press print. please have a look at this print: the next challeby hp_ - Polymer Working Group

A2 thanks for the information on oxidation, Yeah you are right about the material properties of this ceramic the reason i chose zirconia was its thermal conductivity, which is low and heat resistance: [3.bp.blogspot.com] we are currently testing the hotend, we have 10 pieces now, but planning to have more when there is enough interest hp_by hp_ - Developers
Hi Vik, why would i care about oxidisation? has anyone tried this before? i'd like to learn from other experiences hp_by hp_ - Developers
Hi, I've been reading about metal 3d printing today in the forums. and that ceramic might be the key to 3d metal printing. I've been reading a little about this the last couple of days. it seems that aluminium has a melting point of ~660 degrees Celcius. i was looking at ordering 1.6mm 100% aluminium welding wire to give my new hotend a try, its make from zirconia ceramic, and industrial ceramiby hp_ - Developers

Hi Everyone, I have good news, I have been developing a cermic hotend to enable high temperature printing for myself. i had to go through a view version but its now finally working http://3dobjectifying.blogspot.be/2013/03/ceramic-hotend-part-2.html if your interested in trying out this hotend its available at my site: http://www.2engineers.com/shop/ceramic-hotend-chess-for-3-0mm-fillament/by hp_ - For Sale
Hello Everyone, the hotend is available again in 1.75mm and 3.0mm variant The previous version was sold out quick. Types: The 1.75mm version still has ptfe The 3.0mm variant doesn't have any ptfe. http://www.2engineers.com/shop/ceramic-hotend-chess-for-1-75mm-fillament/ The 3.0mm variant I will post online later today. Good news about this hotend is someone is already printing polycarbonaby hp_ - For Sale
Hi Everyone, I just wanted to mention that i'm now printing without a ptfe liner in the ceramic hotend. printing with 3mm PLA fillament. the new ceramic holder(ID=3.2mm) was extra polished upto an ID of 3.4mm checkout the youtube clip below: http://www.youtube.com/watch?v=BLXvNLvI4GA and image: https://www.dropbox.com/s/n60qlpqpgjj7b0n/DSCF9209.JPG the Letter R printed really nice, I got itby hp_ - Plastic Extruder Working Group

Nophead you are probably right.. lets see: U = volts I = amperage R = Ohms U = I . R 12/7 = I I = 1.7 A in the next post i need to change this hpby hp_ - For Sale
Hi alj_rprp, the trick here is that you don't want PLA to stick to the inside when in a molten or near molten state. for example with PEEK the problem is the PLA will bond with PEEK so you need something that will not stick. maybe Korolon 800 is the answer the inner part of the ceramic piece has been polished (ID=3.4mm), 0.2mm can be used for coating. i was also thinking about syperhyperbolicby hp_ - For Sale
