Defect types

Euler marks defects on the recoat and exposure images of every layer. Each defect type has its own color, shown in the Annotations list in the print viewer sidebar. This page explains what each type means, so you can judge what you are looking at.

Defect types

Seen on tells you which image the defect type is marked on. The recoat image is taken after the recoater spreads fresh powder; the exposure image is taken after the laser has melted the layer.

Example	Defect type	Seen on	What it means
	Obstruction	Recoat	Part of the build sticks up into the recoater's path. The recoater can collide with it and be damaged. Marked with a hatched box.
	Warpage	Recoat	The part has deformed, usually from thermal stress, overheating or difficult geometry such as overhangs.
	Pinning	Recoat	Small spots of metal showing through the fresh powder, often from local overheating, edges or supports.
	Spatter	Recoat and exposure	Particles thrown out of the melt pool land on the powder bed and can cause porosity or inclusions.
	Smoke	Recoat and exposure	Smoke or plume over the build, from heavy spatter, overheating or poor gas flow.
	Streaking	Recoat and exposure	Lines or grooves in the powder bed along the recoating direction, usually from a damaged or contaminated recoater.
	Hopping	Recoat and exposure	A repeating ripple pattern across the powder bed, left when the recoater bounces or chatters after hitting a raised area.
	Hole	Recoat and exposure	An area with too little powder, for example from short feeding. It can leave weak or unfused spots when the layer is melted.

Hover over a defect type in the Annotations list to see an example of it.

Showing and hiding defect types

All defect types are shown when you open a print. To hide some of them, or to look at one type on its own, use the eye icons in the Annotations list. See Defect annotation toggle.

Streaking has a Persistent only switch next to its name. Turn it on to hide streaks that don't carry on over consecutive layers, so only the persistent ones are left. The switch is greyed out for devices where Euler doesn't know the recoating direction. An admin can set it with Recoat direction override in the device settings.
