Example of the structure of the design rule database for AM machines

	Rule	Description	Output description	Available Machines
	Rule	Description	Output description	EOS M400	Arcam Q20 plus	Centrifugal finishing
1	Fit within machine	The part(s) need to fit within the build area of the machine	x,y,z (mm): Size of build chamber. If x,y,z > 0 a rectangular area is assumed (width, depth, height). If x,y > 0 & z = 0, a cylindrical chamber is assumed where x is radius and y height of chamber	400, 400, 400	350, 380, 0	250, 250, 325
2	Smallest hole thickness	The smallest inner distance between two surfaces	x (mm): Smallest hole size allowed	0.2	0.4	2
3	Smallest wall thickness	The smallest outer distance of a wall or similar	x (mm): Smallest wall thickness allowed	0.2	0.4
4	Support structure for overhangs	Support structure necessary to support overhang features	x (deg), y (deg): x = overhang angle allowed for rough surfaces y = overhang angle allowed for fine surfaces	30, 45	30, 45
