Embodiment Construction

[0037] figure 1 is a schematic diagram of a printer head 10 of a 3D printing device according to the prior art. The printer head 10 uses printing material in the form of thermoplastic filaments 20 which are fed to nozzles 30 for deposition. Filament 20 is heated to a temperature where it flows easily, and nozzle 30 can deposit (extrude) printing material in layer 40 to create a 3D object. This type of 3D printing setup is relatively fast, cost-effective, and can be used to print relatively complex 3D objects.

[0038] During operation of the 3D printing device, relatively hot printing material is pressed through the nozzles 30 of the printer head 10 and cured on a build plate or previously cured layer of printing material. Such as figure 1 As shown schematically in , layer 40 generally includes raised or rounded edges 45 due to the laminar flow of the molten printing material. Thus, the raised layer 40 results in a relatively rough surface finish of the resulting 3D object...

Abstract

A printer head (100) for a 3D-printing apparatus, comprising a nozzle (110) arranged to extrude a printing material along a principal axis (A) of the nozzle. The nozzle comprises an opening (120) having a first area (130) for allowing a flow of printing material there through, and an element (140) arranged centrally with respect to the opening in a plane perpendicular to the principal axis of thenozzle. The element has a cross-sectional second area (150) parallel to the first area, wherein the second area, in a projection on the first area in a direction along the principal axis, is defined by the first area, such that the nozzle, during operation of the printer head, allows a flow of printing material through the opening and around the element.

Description

technical field [0001] The present invention generally relates to the field of 3D printing. More specifically, the present invention relates to a printer head for a 3D printing device and a method for controlling such a printer head. Background technique [0002] Additive manufacturing (also sometimes referred to as 3D printing) refers to the process used to synthesize three-dimensional objects. 3D printing is rapidly gaining popularity due to its ability to perform rapid prototyping without the need for assembly or molding techniques to form desired articles. [0003] By using a 3D printing device, an article or object can be built in three dimensions in multiple printing steps, usually controlled by a computer model. For example, a sliced ​​3D model of an object may be provided, where each slice is recreated in separate printing steps by the 3D printing device. The 3D printing device may extrude successive layers of extrudable material from a dispenser, and the layers m...
