A school project with Mr Takizawa in Toyo institute of Art.
This is Dice set which includes 4 dice and a box.
0.3 mm nozzle/ 0.18 mm layer
I am using DaVinci 1.0 3D printer by XYZ printing. Also it is modified to a RepRap machine, and I am using Simplify3D to slice models.
nozzle diameter is 0.3mm and Layer pitch is 0.18mm.
Head speed is 1600mm/min
Bottom layer is 4, side is 3 and top is 5.
No raft, with stick paste(Tombow, Shiwanashi PIT).
900 minutes to print. 60 minutes for shaping and constructing.
22m for ABS.
8 pins (ø3*6, SUS)
How to use pins?
In case of traditional machining, making accurate pin-holes on object is not so easy thing, especially if the object is small, has irregular shape or the pin-hole is angled. Because it needs additional assembling jigs to fix.
However, in case of 3D printing, it is pretty easy. It does not need any other cost, except adding holes in 3D data.
The metal pins are enough accurate, so you can make both type of holes lock and roose easily. Also it is much more strong than 3D printing materials, so you can make thin strut or axle. Also it is enough cheap so you can bury under objects, or glue it.
Of course you can use screws. Actually screws are more usual in real world. However you have to tap holes, you can not make loose screw or you can not joint objects face by face because it needs driver.
note. You need "reamer" and "drill chuck" to adjust holes.
