Embodiment Construction

[0047] In the various figures, identical parts are always provided with the same reference numerals, so they are usually also described only once. In particular, the drawings should be understood as representing various components or showing them in simplified form for greater clarity.

[0048] Figure 1a An orthosis 10 from the prior art is shown, which is designed as a thumb orthosis. The orthosis 10 is integrated into the glove 11 . The thumb orthosis protects the thumb joint of the user 19 during fitting operations that are performed very frequently and require a pressing movement of the thumb, for example. This reduces stress on the thumb joint. Figure 1b An orthosis 10 from the prior art is shown, which is designed as an exoskeleton 12 of the forearm and palm. Such an orthosis 10 can also be used for medical purposes, as well as an aid to assist the movements that are often performed especially in assembly operations, for example during continuous manufacturing on as...

Abstract

The invention relates to a method for producing an orthosis (10), in particular an orthosis (10) for producing a glove (11) as an auxiliary manufacturing technique, wherein the method comprises the following steps: providing (1a) a 3D printer (1); providing (2a) a fabric layer (2) by loading the fabric layer (2) to the 3D printer (1); providing a 3D printing material (3) by loading the 3D printing material (3) to the 3D printer (1); performing at least one 3D printing operation (20, 22) to form at least one 3D printed layer (4) directly on the fabric layer (2) in the 3D printer (1); and removing (23) the fabric layer (2) printed with the 3D printed layer (4) from the 3D printer (1). The invention also relates to an orthosis (10), in particular as a glove (11) for assisting manufacturing technology, which is produced in particular by the method according to the invention.

Description

Technical field [0001] The invention relates to a method for the production of an orthosis according to the preamble of claim 1 and in particular to a method for the production of an orthosis for gloves as an auxiliary manufacturing technology. The invention also relates to an orthosis according to the preamble of claim 5, having a fabric layer made of fabric material and a 3D printing layer made of 3D (three-dimensional) printing material. Background technique [0002] An orthosis is generally an assistive device used to stabilize, relieve, immobilize, guide or correct a limb or torso and is produced industrially or by orthopedic technicians, usually for medical prescription. [0003] Fused Deposition Modeling (FDM) or Fused Filament Fabrication (FFF) generally represents a manufacturing method originating from the field of 3D printing, in which a workpiece is formed layer by layer from fusible plastic or molten metal. [0004] Orthotics can be produced for medical use or ...
