    How long does the 1 Litre of Resin last?

    Anyone have any idea how long 1L of Resin (the $60 option) will last? Any clue how many medium sized objects that would print?

    Resin cost: We are working on an all new, extremely high perfomance, low cost resin that is specially formulated for the Peachy Printer! In the past we have seen resin prices of $200/litre. Thanks to Josh Ellis and his company Maker Juice, we now have a fast acting resin that only costs $60/litre! You can also get more use out of your resin by using resin fillers. The little cube pictured above is about 2 cubic centimetres. With one litre of resin you could print approximately 500 of them, each costing around $0.12 to make. The hollow cube pictured below could be printed approximately 2000 times out of one litre of resin at a cost of about $0.02 each!

    Hello Rainday,
    most 3D programs will offer you to calculate the volume of an object, and you can usually hollow out a part or construct a fill structure that will increase stability while still saving weight.
    Of course with the resin it's best practice to leave a hole to drain out excess resin, but it's manageable.

    With my "regular" FFF printer I can print a lot with 1kg, as I only print small things.
    On the other hand, one bulky object may use up a lot of plastic;
    What are you planing on printing?

    I'm very new to 3D printing, but how would there be resin in the structure with this printer design? Wouldn't the water (which would need to be drained still) displace the resin out of internal structures while printing?

    Yes, but let's say you a building a bowl and you printing it upward. The bowl will fill with resine/water. It will be easy to remove, but not if you close the top too.

    Yeah, but the interior will remain filled with water, which the resin is floating on top of. When the top closes off, the resin will be above the closure and the interior will be full of water.

    If you have small enclosed spaces in your object (shorter than the depth of the floating resin) they could be completely sealed before the water displaces the resin. Then there would be uncured resin encased in the print.

    I'm sure it won't be hard to stick a needle in, mid print, to leave a whole when you pull it out. Problem solved

    yeah, you could place a needle and extract it, make a hole with a drill and let it out, etc... it's not a "big" problems IMO

    Yes ;-) But the point was most things on thingiverse and other sites are designed as solid models, hollowing out can sace material cost :-)
