Abstract
An optical component (10) is disclosed comprising a plurality of layers (11), each layer comprising a core portion (13) and a shell portion (15) enveloping the core portion, wherein the core portion is made of a first material and the shell portion is made of a second material, the first material and the second material having a different transmissivity. Also disclosed are a luminaire comprising such an optical component and a method of manufacturing such an optical component.
Claims11
A method of manufacturing an optical component by means of fused deposition modeling using a 3-D printing apparatus,
- wherein the 3-D printing apparatus comprises,
- an extruder nozzle, and
- a filament feeder for feeding a preformed core-shell filament having a core of a first material and a shell of a second material through the extruder nozzle, or a plurality of filament feeders including a first filament feeder for feeding a first filament comprising the first material through the extruder nozzle and a second filament feeder for feeding a second filament comprising the second material through the extruder nozzle;
- and
- the method comprises the step of:
- 3-D printing a stack of layers with the 3-D printing apparatus by feeding the preformed core-shell filament or the first filament and the second filament through the extruder nozzle such that molten second material surrounds the molten first material to form the optical component, wherein at least some of the layers of the optical component comprise a core portion made of the first material and a shell portion enveloping the core portion made of the second material, the first material having a different light transmissivity to the second;
- tuning optical properties of the optical component by providing predetermined dimensions of the core portion and shell portion layer.
