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

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. |
