Definitions

  • the present invention relates to a manufacturing method where, items are made similarly the way a variety of insects build up their habitats.
  • Machines which allow this kind of manufacture of matter consists generally of either: a) robot arms with at least 5 axis of freedom of movement, b) light framed numerically controlled machine which would have a head or a number of heads which would have 3 to 5 axis of freedom of movement.
  • Each head or robot arm have specially designed head allowing excretion or projection of particles or fibres of matter on a small to microscopic scale in such a controlled fashion so as to allow buildup of the material and retention of shape.
  • Material needs to solidify sufficiently straight after deposition (pre-cure) and then full curing could be induced consequently.
  • additional layers could be applied in similar fashion or by any other means, like laminating thin layers consisting of carbon fibres & epoxy.

  • CM-AM Computerised Macro-Assembly Manufacture 1s not the robot or NE machine alone which allows computer programmed movements, but 1s this unique usage of CNC machines or robots in combination with: a) special heads designed for material deposition b) a particular type of material with suitable properties, c) computer software which allows various methods of bulldlng-up walls of objects by having defined cell macrostructure.
  • CM-AM was first tried with type of head where material deposited was clay. Schematic of this 1s shown 1n F1g. 1 and actual example of shape created 1s shown in F1g. 3. Its wall macrostructure 1s shown and this can be represented by a simple algorithm as shown 1n Page 9. Next trial was with thermoplastic material as made by the container as shown in Fig. 2. There are many types of materials with suitable designed heads possible for this type of manufacture, some of which are listed below with brief description of applications.

WME Head for CM-AM
  • Wax material is the first material when one looks at analogies of this method of manufacture in nature. Bees are making their beehives in this fashion.
  • This material has also wide application in engineering, for example in modeling of 3D components, but particularly in manufacture of strong metal components by method of "investment casting".
  • a model of the component is made out of wax, by standard machining methods, then this component is covered with slurry of ceramic material which eventually dries into a high temperature resisting shell. After melting away the wax core, a cavity remains into which molten metal is cast to a required shape. Shell is consequently broken away. Because of the low melting temperature of wax, it is relatively simple method of designing a head for excreting wax, under pressure, with controlled flow, and with such ambient conditions at the entrance nozzle so that the material solidifies soon after it leaves the nozzle. Variations in design of the head can be due to a particular application, from simple 3 axis head for making simple thin shell 3D models to 5 or more axis head where characteristics like surface texture or wall thickness could be controlled as well.
  • Clay was first material to try CM-AM. Motorised syringe was mounted on the CNC machine as illustrated in Fig. 1. This was filled with clay of sufficient plasicity. The machine was programmed to produce shape as shown in Fig. 3. There are many software packages to simplify this kind of programming, so called CAM (Computer Aided Manufacturer). The particular CAM used in this case is Smartcam Advanced 3D. Sample (start and end) of the code generated is also shown in Page 8. Simple algorithm was also created to allow automatic generation of the cell structure as shown in Fig. 3. Essential aspects of this algorithm are shown in Page 9. With some infringements the type of head with appropriate material would allow making directly for example:
  • CM-AM with this materials is the possibility of exotic shapes out of refractory, high temperature materials, without need for expensive machining of hard materials. Full utilisation of hi-tech, expensive materials without any wastage. Low tooling-up cost and fast flexible designs. PME Head for CM-AM
  • the present invention differs completely, in that material being excreted from a nozzle of a special head and is illuminated by the focussed laser beam as it is leaving the nozzle, thus causing polymerisation and therefore solidification right after it was deposited onto already existing structure.
  • SUBSTITUTESHEET complex shapes for deposited layers do not have to be in horizontal planes (given by the surface of fluid -in the existing method), but could be gradually assuming any orientation because only minute portion at the end of the excretion nozzle is in fluid form.
  • filing and reinforcing materials could be added to improve the physical properties of finished components.
  • glass or carbon fibres or particles For example glass or carbon fibres or particles.
  • this could be used not only for 3D modelling, but for making finished products with desired strength variation of this head is where continuous fibre of, for example, glass or carbon is fed together with polymerising material which bonds fibres together. The process would become similar to weaving basket or cloth, or simply laying layer by layer first in one direction, and then if necessary in other direction. In this fashion it is possible to create strong, tnin shell structures, or of more complex wall (like honeycomb) structures.
  • Epoxy. is mixed with catalyst prior to leaving the nozzle, and is further assisted in fast pre-cure by appropriate ambient conditions and further accelerated by, for example focused laser beam, full curing is achieved in given time. This can be accelerated by post-cure low temperature baking.
  • Variant of this design is a composite head where two different types of materials are being deposited simultaneously. For example head creates tube with thin wall, middle of which is filled with low specific gravity material core. This tube is deposited layer by layer, with variable width or at an angle.
  • Metal deposition with CM-AM is proposed to be used in two basic variations: a) Molten metal is deposited or sprayed or sputtered. b) Solid wire is fed from the head and at the some time it is welded to already existing structure, this also softens the wire allowing it to assume required shape more readily.
  • Second or more layers can be deposited consequently at different angles to give the structure required strength in different directions, or a process similar to basket weaving could be used, where more intricate, multiple head design would be required.
  • Composite head or a number of heads can be also used where a layer of metal is covered with another layer of different material, say of epoxy. This would give the structure for example imperviousness, protecting the core ⁇ .c_tal material from external elements.
  • Thermoplastic material is the first material which we tried to produce practical and strong components by this method of manufacture. (Clay samples on page 3 above served purpose but were too brittle to be of any practical use.)
  • thermoplastic materials for example Polypropylene at 200-300°C
  • head for excreting this, under pressure, wit h controlled flow, and with such ambient conditions at the entrance nozzle so that the material solidifies soon after it leaves the nozzle.
  • Fig. 2 shows typical head design. Variations in design of the head can be due to a particular application, from simple 3 axis head for making simple thin shell 3D models with simple 3 axis head for making simple thin shell 3D models with simple macrostructure to 5 or more axis head where head can be aligned with direction and inclination of the surface, and this way for example preheating of existing surface, each wall of individual cells from which walls are made.
  • thermoplastic components for example prototypes of exotic shapes can be made without making expensive tooling for injection moulding. In many applications where small quantities and very exotic shapes are required this could be sufficient, and if required components could be finished by applying lamination on its external surfaces.
  • SUBSTITUTESHEET Speed of manufacture can be substantially improved with multiple head machine design, in cases where additional complexity would be justified by increased rates of production.
  • This method of manufacture would be ideal for manufacturing out in 5 space, because of special requirements and also because of the special conditions of zero gravity and vacuum. a) One universal lightweight machine could be used to manufac ⁇ ture any object. b) 100% utilisation of available resources of raw materials.
  • Each facet represents external side of a cell as shown in Fig. 3(b) or Fig. 3(c).
  • a triangle On each of these facets is constructed a triangle, with the two other sides of equal length, and where the height of this triangle represents the wall thickness.
  • Corresponding internal cells are created by joining aspects of these triangles, length of these is therefore related to curvature of the shape.
  • Walls can be build-up by having the same structure applied a number of times, if necessary of finer cell size then external smoothness of walls would call for.

Abstract

On décrit un procédé de fabrication permettant de réaliser des articles d'une manière semblable à celle utilisée par les insectes pour construire leurs nids. Il s'agit d'assembler d'une manière ordonnée prédéterminée et à l'aide d'un liant de minuscules particules ou brins de matière pour créer un objet de la forme souhaitée. Selon l'invention cette opération est réalisée par un robot ou une machine à commande numérique qui commande la position d'une tête spécialement conçue et dont la fonction est de distribuer une matière spéciale. Ladite matière se solidifie rapidement et conserve ainsi sa forme programmée.
