Infill Percentage: 3D printing is used to manufacture objects ranging in density from hollow to solid. How closely to one another the roads of material are deposited determines the infill percentage which then determines density and strength of the object. Common infill percentages for 3D printers are 0, 5, 10, 15, 20, 25, 50, 75 and 100 percent.
Durometer Rating: The Durometer scale is a device for measuring the hardness of a material, typically of polymers, elastomers, and rubbers. Higher numbers on the scale indicate a greater resistance to indentation and thus harder materials. Lower numbers indicate less resistance and softer materials.
Layer Height Explained
Layer Height: is a measure of the height of each successive addition of material in the 3D printing process in which layers are stacked.
