Drill Size 60

Two threaded holes create a gap

Punch, Drill, Tap

hole goes through the entire object

A specific depth through some of the object.

Material Extrusion and Vat photopolymerization

Low Cost, tough, durable, withstand high temperatures

elasticity, stretch, and bend

easy to use, dimensional accuracy, low cost,

lightweight material, dissolvable support for ABS

easy print, smooth finish, water resistant

tough, semi-flexible, high impact and abrasion resistance

PLA or ABS infused with Carbon fiber for strength and stiffness

ABS alternative, good for outdoors, UV, Temp, and impact resistance

CAD, STL export, slice, print

Clearances, Long Bridges, Scale, Bad adhesion

Glass, Anodized Aluminum, Powder coated metal, Glazed ceramic tile, Marble

Spread out & True Value

Consistent and imprecise value

Find the Partial Derivative in terms of one variable, all other variables are treated like constants.

Finding all Partial Derivatives squared, add them together, find the square root.
