Please review the quality assurance checklist below to verify that each model was properly printed.
If you are a 3D print on demand service provider, please send photos of the base, top, sides and vise attachment of sample printed models to the consignee.
Have this checklist displayed on a mobile device when inspecting each 3D printed sample model.
Any model that does not meet the standard for all the quality assurance checklist items must be reprinted in accordance with the instructions outlined below.
The base of each model should be smooth, clean, and display three semi-engraved model numbers, a gender symbol, and two drilling direction arrows to assist with model identification and proper orientation of the simulator.
If the semi-engraved features are not visible, the model should be reprinted with the proper settings with no raft (click here to view reference screenshot) and no support material (click here to view reference screenshot). If the base is not smooth or clean (click here to view closeup photo), clean the build plate before reprinting. For build plates that require glue for adhesion of the printed object, apply a thin, smooth, and even layer of glue to the cleaned build plate.
If the base is open, the model should be reprinted with the proper settings of Bottom Layers: set to default value and not set to "0" (click here to view reference screenshot).

Inspect the top.
The top of each model should display the outer cortex and inner cancellous bone porosity and microstructure because these features provide visual fidelity to the surgical simulator. Use a ruler or calipers (not shown) to verify that the cortex thickness is 5.5 mm. If the cortex thickness is not 5.5 mm, then the model should be reprinted with Wall Thickness set to "5.5 mm."
If the inner cancellous bone features are not visible, the model should be reprinted with the proper settings of Top Layers set to "0" (click here to view reference screenshot).
The surface of the bone model should be smooth to provide visual and tactile fidelity of the surgical simulator.
If the bone model surface is uneven or missing material, the model should be reprinted (i) using brand new white PLA filament fresh out of the sealed package, and (ii) with the proper settings including changing print speed back to default values for the Generic PLA filament profile and reducing the layer height to 0.2 mm or less.
If the bone model surface is uneven or missing material, the model should be reprinted (i) using brand new white PLA filament fresh out of the sealed package, and (ii) with the proper settings including changing print speed back to default values for the Generic PLA filament profile and reducing the layer height to 0.2 mm or less.

Inspect the vise attachment.
The entire surface of the vise attachment should be smooth with no missing material and the angled surface of the vise attachment should have no filament drooping.
If the angled surface of the vise attachment is uneven or has drooping filament (click here to view closeup photo), the model should be reprinted (i) using brand new white PLA filament fresh out of the sealed package, (ii) with the proper settings including changing print and fan speeds back to default values for the Generic PLA filament profile, and (iii) while reducing the layer height to 0.2 mm or less.
If any surface of the vise attachment is uneven (click here to view closeup photo) or missing material (click here to view closeup photo), the model should be reprinted (i) using brand new white PLA filament fresh out of the sealed package, and (ii) with the proper settings including changing print speed back to default values for the Generic PLA filament profile and reducing the layer height to 0.2 mm or less.
