Publication number: 20210107063Abstract: According to some aspects, degradation of material in a sintering additive fabrication process may be mitigated or avoided by fabricating parts within a chamber that includes one or more thermal breaks. The thermal break may be implemented using a variety of structures, but generally allows material in the chamber close to the surface to be maintained at different temperatures than the material further from the surface. For instance, as a result of the thermal break, parts located within the material of the chamber that were formed earlier during fabrication may be kept cooler to avoid damage to the parts yet the upper surface (sometimes called the “build surface”) of unconsolidated material may be heated enough so as to require minimal additional energy exposure to trigger consolidation.Type: ApplicationFiled: September 16, 2020Publication date: April 15, 2021Applicant: Formlabs, Inc.Inventors: Robb Morgan, Luke Plummer, Christopher Auld

Publication number: 20210107065Abstract: A tool drive unit for a turning device for machining workpieces has a tool holder driven in a displaceable manner along an infeed direction by a first linear motor and driven in a pendular/displaceable manner in a direction transverse to the infeed direction by a second linear motor. Both linear motors have a moving coil/piezo element. The turning device has a main infeed drive, which produces a primary infeed movement of a turning tool in an infeed direction, and has a main transverse drive which produces a primary transverse movement in a transverse direction transversely to the infeed direction. The turning device has a secondary transverse drive whose movements are oriented in the same direction as the main transverse drive, wherein the turning tool and the axis of rotation can be moved towards one another and away from one another by the superimposition of primary and secondary transverse movements.Type: ApplicationFiled: October 6, 2020Publication date: April 15, 2021Inventor: Roland MANDLER

Publication number: 20210107069Abstract: A work-stop assembly in a work-holding-collet is formed of a main work-stop body selectively mounted on the rear of the work-holding-collet and defining a longitudinal through passageway aligned with the collet mouth. First and second work-stop position adjusters allow coarse adjustment of the position of a work-stop element by one of the adjusters while the work-stop assembly is removed from the work-holding collet and allow more precise adjustment by the other adjuster after the work-stop assembly is mounted to the work-holding collet. One of the adjustments employs a slidable relationship between the adjuster and the passageway, and one of the adjusters carries the work-stop element for axial movement in the work-holding-collet to set an adjustable depth limit for a workpiece inserted from a workpiece-receiving mouth at the front of the work-holding-collet.Type: ApplicationFiled: October 11, 2020Publication date: April 15, 2021Inventor: Daniel R.
