MakerbotTopBlock.JPG
Block Project Top Block Get used to the machine, learn about shrinkage and expansion, Test Post Print Processing Techniques. .008” = .6% shrinkage in Z

.004” = .2% shrinkage in Y .003” = .4% expansion in X

Est.: 91 min

Act.: 81 min

Sanded down to fit in the metal block. Holes were reamed successfully.
MakerbotArches.JPG
Arches .125” To determine Makerbots corner capacities and arch radius problems. Corners on the ZY and ZX planes are sharper than corners in the XY plane. Drooping occurred when .375” of overhang exists Est.: 15 min

Act.: 13 min

None

1” Cube Standard Resolution (.27) To determine Makerbots corner capacities and arch radius problems. .004” = .4% shrinkage in Z

.002” = .2% shrinkage in Y .003” = .3% expansion in X

Est.: 30 min

Act.: 27 min

Sanded on belt sander. Won't smooth evenly.
Makerbot1x1CubeLowRes.jpg
1” Cube Mid Resolution (.15) To determine % of shrinkage and expansion in each axis and time difference. .004” = .4% shrinkage in Z

.002” = .2% shrinkage in Y .003” = .3% expansion in X Resolution doesn't effect Shrikage/Expantion.

Est.: 31 min

Act.: 38 min

Saturated with water. Water was not absorbed. Object was 50% buoyant at 10% hallow.

1 x .5 x .5 Rectangle Built with 4 Shells for machining. .001” = .2% expansion in Z

.010” = 2% expansion in Y .004” = .4% expansion in X

Est.: 8 min

Act.: 8 min

Milled one edge at Aluminum speeds which resulted in perfect smoothness. Learned 4 layers = .0848" thickness.
