Beschreibung
Zusammenfassung:	A parts fabrication apparatus has a staging fixture that is configured to position at least a portion of a molded plastic assembly that has a connective runner portion with at least one molded part extended from the connective runner portion by a severable gate portion. A laser source is energizable to direct toward the severable gate portion, from a laser output aperture positioned beneath the staged plastic assembly, a coherent light beam having sufficient energy for melting the gate portion and releasing the molded part along a drop path. A support is disposed to deflect the drop path of at least a portion of the released molded part in a direction away from the coherent light beam.
