3D-Druck: Kristallisationskinetik von Polyamid 12 während des selektiven Lasersinterns

Powder Bed Fusion (PBF), auch als Selektives Lasersintern (SLS) bezeichnet, ist eine Technologie zum schichtweisen Aufbau von 3D-Objekten, bei der ein Laserstrahl selektiv über einen vordefinierten Bereich der Pulverschicht fährt. Eines der dabei am häufigsten verwendeten Materialien ist PA12.
