I am from South africa and I would like to build a Littlerp2. Are you able to provide an 3d part assembly drawing (solidworks, rhino, spaceclaim or other) of the machine for those of us that may need to redesign to suit the parts or fabrication methods we have available to us. I have access to a sheet metal workshop and could more easily manufacture the body of the machine in 2mm aluminium. (Also we are metric). I also would like the projector inline and below the vat. If I can get 3d assembly drawing to work from it would make this more possible. I am more than willing to provide you with the design once completed so that you can see if you want to include it for others.
I tried to contact you via your email message thing at bigcartel.com but I don't think it's going through.
I'll see what I can do, STEP ok?
A STEP will be fine thank you. Where will you post it or do you need an email address from me? Also, excuse my ignorance with regard to this; Where would I be able to purchase a littlerp2 kit? I am also considering morphing the littlepr2 into a smartphone/daylight resin printer. I see potential for this in that 4k phone screens are affordable when compared to 4k projectors. What are your views on this? (My interest is in fine detail jewelry design).
I will email you, the STEP still isn't a general consumption thing. I wanted to rebuild the design in onshape but never really had the time. I still have some kits, if you email me what you are looking for we can go from there. Regarding smartphone, it really depends. Typically jewelers don't want to make molds and want a good castable resin. I am not aware of a daylight castable resin that is good, not to say it doesn't exist but I just haven't seen it. You really limit your resin availability with daylight, similarly with UV LCD.
Additionally the 5k lcd based resin printers are already pretty cheap and would have a similar pixel size as a 4k smartphone ... in the 42-50micron range. For jewelers this is kind of a borderline usable range, most are going to want 25micron if they can, some want even lower. If you want to go daylight you can just use the lcd's that the d7 and other printers are using but keep the backlight etc.. I think the lack of resin options will be a barrier though. LCD printers are getting very popular, more because of cost than performance. I still think there is a market in dental / jewelry by focusing on high pixel density and specialty resins.
