Definitions

  • the present invention is directed to a method for preparing a three- dimensional replica of a subject or object, in particular a method for producing three dimensional sculptures.
  • a very well known technique for preparing the final work is by means of the lost wax casting process.
  • a wax replica is prepared and then encased in a mould.
  • the mould is heated to remove all traces of the wax and leave a cavity.
  • Molten metal is poured into the mould to fill the cavity left by the wax.
  • the mould is then removed to reveal the finished article in a rough cast form.
  • the article is then finished using suitable techniques.
  • GB 2 377 506 discloses an apparatus for reproducing a human head in three- dimensional form.
  • the replica is prepared by removing material from an oversize blank of thermoplastic material using a data set of coordinates of the surface of the subject's head.
  • US 5,736,201 is concerned with a process for making a replica of the head of a subject in the form of a doll's head.
  • the process comprises scanning the head of the subject with both a laser scanner and a video camera, to produce data signals containing contour information and colour information.
  • the countour signals are used to prepare a three-dimensional replica of the subject, after which the colour signals are used to colour the replica.
  • CN 1105035 C discloses a method for manufacturing three-dimensional metal statues.
  • the method comprises scanning the subject to obtain data on the shape and configuration of the subject.
  • the data thus obtained are input into a computer, which is then used to prepare an epoxy resin model.
  • a silicone elastomer mould is prepared from the resin model, which is in turn used to prepared a wax model.
  • the wax model is used in a lost wax casting process to prepare the final cast metal replica.
  • KR920008779B discloses a method of sculpting using a laser and an apparatus for the same.
  • the method comprises taking an image of the subject and storing the image data in a memory. A portion, but not all, of the image data are scanned and used to generate a carved object.
  • FR 2855959 is concerned with a method for creating an item of so-called personal equipment, in particular a prosthesis for use by a person.
  • the method comprises scanning the limb or portion of the person to be fitted with the prosthesis.
  • the image data are modified, in particular to take into account the surfaces of the limb or portion of the person that are to provide support.
  • the prosthesis is then formed using the modified data set.
  • the method of FR 285595959 necessarily provides a finished object that is, at least in part, has opposing surfaces to the scanned limb or body portion. Thus, the method cannot generate a replica of a scanned object.
  • WO 2004/077185 describes a method for producing an article, in which an object is scanned to provide a set of image data, and converting the scanned data into surface data representing surface characteristics of the model, from which instruction data for a computer-controlled machine tool are generated. Thereafter, execution of the instruction data is simulated to generate a representation of the reproduction of the article as will be produced. The results of the simulation may be used to improve the quality of the reproduction.
  • US 5,184,306 is concerned with a method of reproducing three dimensional objects, in particular for use in dental applications.
  • the method comprises acquiring a set of image data of the subject and constructing a three-dimensional computer-based model of the subject. This model is superimposed on ideal geometry data which are stored on the computer. The ideal geometry data are then modified in light of the three-dimensional image , data and then used to prepare the final object.
  • a method for the preparation of sculpted objects comprising the steps:
  • the method of the present invention employs scanning technology to provide an image data set of the object to be reproduced. This ensures that the reproduction is accurate.
  • the data set is modified as required, as described hereinafter, in order to produce the completed sculpture.
  • the method may be used to prepare a range of reproductions or sculptured objects, in particular statues of people and/or animals, busts and cameos.
  • the method may employ any suitable scanning technique in order to obtain an image data set of the object being reproduced.
  • the image data set will contain data of the object in three dimensions, in turn allowing a three- dimensional reproduction to be produced. Accordingly, the scanning technique employed must be one that provides a three-dimensional data set.
  • Suitable scanning techniques are known in the art and suitable scanning systems are commercially available. Preferred scanning systems include 3D non-contact laser scanners/digitisers, for example the Konica Minolta Vi910, commercially available from Konica Minolta Sensing Europe B.V.
  • the scanning step is conducted to obtain an image data set of at least a portion of the object being sculpted and, in some embodiments, a complete image data set.
  • the object is preferably scanned a plurality of times, in particular at least three times, more preferably at least six times and the image data set compiled from the data obtained from each scan.
  • Each scan will typically last from 1 to 5 seconds, more particularly about 2.5 seconds.
  • the scanning step of the method may be carried out to generate an image data set for the entire object.
  • the reference to the image data set being for the entire object is to be taken to mean all the image data necessary to prepare the desired sculpture.
  • the image data will be of the entire object.
  • the data set may be obtained for just a portion of the object required in order to prepare the desired sculpture. The reasons for this are as follows.
  • the object is to only have a portion of its surface scanned, it is preferable to assess the object before the scanning stage, in order to determine the nature of the features of the object and the detail thereof.
  • the threshold value of the level of detail to be tolerated is set by the RP system, in particular the resolution to which the system can operate, the materials being used and the length of time to be taken in preparing a reproduction from the image data set.
  • the higher the resolution of the image data set, that is the higher the level of detail the longer the RP system will take in translating the image data into an object.
  • the detail threshold will be set by the length of time to allocated to the RP system for preparing the replica.
  • the present invention in this embodiment, elects to have the scanning system operate at its highest resolution and omit those features that have too much detail for subsequent sculpting using the image data set. Portions of the object surface have a sufficiently low amount of detail, for example a face, clothing or the like, are imaged at the high resolution to provide a partial image data set of the object. It will thus be appreciated that the present invention defines the portions of the object to be scanned by the nature of the surface features, rather than by adjusting the sensitivity or resolution of the scanner, as is relied upon in the prior art.
  • the resulting partial image data set is modified to include image data for the omitted portions of the object.
  • Software available to manipulate and modify an image data set in this manner is well known and commercially available in the art and. includes various computer aided design (CAD) packages and reverse engineering software packages, which allow a user to add features to an image. Examples of suitable commercially available software packages include GeomagicTM, commercially available from Interplex Ltd., and Magics
  • the omitted portions of the image data set may be added by hand or automatically, in order to create a modified image data set of the entire object to be reproduced.
  • the entire surface of the object to be sculpted is scanned and an image date set of the complete object obtained. Again, this will be carried out using the scanner at a high level of resolution, that is to capture a high level of detail.
  • the image data set is then modified to identify those portions of the image data set that exceed a threshold detail level determined by the subsequent processes to be undertaken.
  • the image data set is then modified to bring the detail level of the entire image to below the threshold value.
  • Software available to manipulate and modify an image data set in this manner is well known and commercially available in the art and includes various CAD packages and reverse engineering software packages, as aforementioned, which allow a user to modify features in an image. In this way, the level of detail of the image data set may be altered by hand or automatically, in order to create a modified image data set of the entire object to be reproduced.
  • the image data set is adjusted according to a threshold for detail that is determined by the subsequent processing techniques to be employed, such as RP, as described hereinbefore.
  • the image data may be altered to remove unwanted features or alter features according to the sculptor's or subject's wishes. For example, blemishes and marks on a person's skin may be removed, as desired.
  • the scale of the image data may be adjusted, in particular to increase or decrease the scale of the object to be prepared from the image data set. In many cases, for example in the case of the sculpting of an animal or person, in particular a full figure or a bust, the finished sculpture will be required to be considerably smaller than life-size. This will reduce both the size and weight of the completed sculpture, for example, a replica at half scale having only one eighth the volume and material of the full-size object.
  • the image data set may be modified to change the ratio of the sizes of the image in each dimension.
  • the image data set is modified to reduce the scale of the image in one dimension.
  • the image data set may be modified to reduce the image along the z axis, while retaining the size of the image in both the x and y axes.
  • a modified image data set may be prepared that can be used to prepare a replica in the form of a medal, medallion, plaque or cameo.
  • the image data file may be modified in this way without introducing major distortions to the overall image and the final appearance of the replica.
  • the image data set may be modified to adjust the scale of the image in one dimension or along one axis by a factor of from 0.1 to 0.5, for example 0.25, without the final replica being distorted.
  • the modified image data set is used in the subsequent processing, which creates a replica and finished sculpture according to the modified data set. This may be achieved in a variety of ways.
  • the modified image data set is used in the direct preparation of the final sculptured object.
  • the modified image data set may be used as the input to a computer controlled milling machine, lathe or the like.
  • the modified image data set is input into a rapid prototyping (RP) system.
  • Rapid prototyping is a modern technique, by which objects are constructed using the successive deposition of material in a solid freeform fabrication (often referred to as three- dimensional printing) according to a set of computer generated instructions.
  • the RP system deposits liquid or powdered material in successive layers in accordance with a set of profiles or contours communicated to it, in order to construct the completed article. Suitable RP systems are known in the art and are commercially available.
  • RP systems and techniques include stereolithography apparatus (SLA), selective laser sintering (SLS), fused deposition modeling (FDM), laminated object manufacturing (LOM), inkjet systems and three dimensional printing (3DP)

  • SLS selective laser sintering
  • FDM fused deposition modeling

  • ABS acrylonitrile butadiene styrenes
  • the RP system may be employed to deposit a single material to construct the reproduction. Alternatively, two or more materials may be used.
  • a two-component system in which one component has a low melting point or is soluble in a suitable solvent and such component may be removed by suitable heating or dissolving in a solvent.
  • a reproduction may be prepared that is hollow, for example to reduce overall weight of the sculpture.
  • Suitable conversion of the modified image data file to a format readable by the RP system may be required.

  • Other suitable conversions and interfaces will be known to the person skilled in the art.
  • a particularly preferred embodiment in which the image data set is used directly in the preparation of the finished sculpture is in the preparation of a cameo.
  • the image data set is used directly in a process, such as milling or rapid prototyping to prepare a cameo. It has been found that cameos of a very high quality comparable to those prepared using conventional and traditional techniques may be prepared quickly and cheaply, by persons with little or no skill in the art of cameo making.
  • the image data set may be employed directly in the preparation of the completed sculpture, for example using the various RP techniques discussed hereinbefore.
  • the image data set is used to prepare a replica of the object being sculpted.
