	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.
	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
	Arches .250”	To determine Makerbots corner capacities and arch radius problems.	Similar results, Corners on the ZY and ZX planes are sharper than corners in the XY plane. Drooping occurred when .375” of overhang exists	Est.: 18 min Act.: 17 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.
	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.
	Cone	Printed to determine circle problems.	.01% shrinkage in Y .05% expansion in X Error Printing in Z Lost .35" of tip.	None Est.: 87 min Act.: 91 min
	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.
