spatter

The killer left behind a grisly scene, spattering the walls with blood before he was spotted in a ski mask by one of the two surviving roommates on his way out through the glass doors.

His star status was secured with his portrayal of Dexter Morgan, a Miami-based blood spatter analyst who moonlighted as a serial killer in “Dexter.”

Inside Mayada’s home, the living room has a frieze of shrapnel spatter covering a wall.

In the video clip the torn shirt can be seen tied just above an elbow - blood was on his lower arm, trousers and spattered by his seat.

But the big challenge is that metal parts created with additive manufacturing have defects -- like pores, or "voids," rough surfaces and large spatters -- that significantly compromise the finished part's reliability and durability.
