Abstract
A device for deposition of liquid or molten material. The device comprises a tool 2 and a control system 8 to set and manage the surface energy 4 of the liquid or glassy zone of the material during transition to the solid phase by application of appropriate forces such as tensile forces. The tool may comprise a heated rod and a feeding mechanism 6 may be used to supply new material continuously or intermittently to the tool during deposition. An electro-mechanical device such as a CNC machine 7 may be used to manipulate the tool in three-dimensional space to allow finely controlled tracks or three dimensional structures to be built.
Description
Device for controlled material deposition The invention relates to a device for controlled material deposition for use in manufacturing technologies. The device consists of a tool and control system to set and manage the surface energy of a liquid or glassy zone of material during transition to the solid phase by application of appropriate forces. Some applications for this device may be in additive manufacturing and rapid prototyping technologies to produce high quality, fully dense parts.
Several technologies exist to add new material to a surface by converting a solid material into its liquid phase, usually by input of heat energy until the material's temperature rises above its melting point. Material deposition technologies can be used to coat existing surfaces such as in laser cladding or by deposition of multiple layers to create three dimensional objects such as in Selective Laser Sintering. All these technologies suffer from several drawbacks because the material deposit naturally tends to minimise the surface area to volume ratio in order to reduce its surface energy, usually leading to the material forming a spherical shape. First, geometries that existing technologies can build are limited. Building ledges and overhanging shapes beyond certain angles is impossible without supporting structures. The self-weight of the layer being deposited, in combination with the reduced surface area in contact with the previous layer creates poor adhesion therefore requiring support structures during solidification. Second, the material's tendency to form a spherical droplet causes poor wetting and adhesion to the surface. The problem is particularly exaggerated when fine tracks are being produced therefore reducing overall strength.
The device for material deposition uses a tool to exert appropriate forces on a zone of material to counter-balance some of the surface tension forces of the boundary surface and change the surface energy, usually to a value greater than would be assumed by the same material if the surface boundary were spherical in nature or had a positive curvature.
The device stabilises the deposition process by preventing the droplet from assuming a spherical shape. This improves wetting and adhesion to existing surfaces and allows the building of shapes on a surface or in free space including but not limited to overhanging shapes and ledges. The act of exerting a force while the material is solidifying acts as a supporting structure in itself and prevents any undulations in deposited tracks and surfaces. The overall surface finish may be both smooth and highly polished.
The material must be a substance capable of having a liquid phase and a solid phase including but not limited to metals and certain polymers.
Figures 1 and 2 show possible configurations for the device by using a tool 2 that comes into contact with the deposit material. An amount of liquid or glassy material 1 is deposited onto this tool using a feeding mechanism 6 or by moving the tool to or within a pre-placed volume of material. The volume of material must be such that its self-weight does not cause it to become detached from the tool. The droplet may already be in its liquid or glassy phase, or the tool may be used to facilitate the conversion of material into its liquid or glassy phase. The tool may be attached to an electro-mechanical device such as a multi-axis CNC machine 7 to move this tool in three dimensional space. The tool may then be displaced until a portion of the liquid or glassy material adheres to a surface 5 or a pre-built feature whilst remaining in contact with the tool.
The tool is then moved away from this surface or feature to exert sufficient force such as to change the surface energy of the boundary surface 4. A feedback control system 8 is used to set and manage this surface energy value to produce well controlled high quality material deposits. A supply of inert gas such as argon, or a supply of flux may be used in the solidification zone to reduce the effects of oxidation and or to act as a cleaning agent.
As the tool tip moves, material is deposited by capillary action 1. While material is being deposited, new material may be supplied to the tool continuously or intermittently.
Alternate configurations of the above device may involve a portion of the tool to be submerged within a bed of material; the material may also be fed to the tool in liquid or glassy form and the tool tip may facilitate the conversion to a solid phase.
