Patents by Inventor Elis Carlstrom

Elis Carlstrom has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9545669
    Abstract: The present invention relates to layer manufacturing, more particularly to a method for additive layer manufacturing of objects comprised of more than one material with free-form capability for all included materials. The invention can for example be used for producing packaging for Microsystems where the ceramic acts as an insulator and the secondary material is used to produce electrical or optical 3D conductor lines or electrical or optical 3D vias. The fine powder used in this method enables it to be used for building components with small feature size and demand for high precision. Other intended uses for this method is to build small mechanical precision parts or grinding tools, dental objects or medical implants.

  • Patent number: 6607386
    Abstract: A dental product is produced from material in powder form. In a first manufacturing stage, the product is given a shape which is larger than its final shape, and in further manufacturing stages the product is subjected to material shrinkage, sintering and working in order to obtain its final shape. Metal powder is applied to the mold tool, and the mold tool with the applied metal powder is placed in pressure-generating equipment where the powder applied to the mold tool is subjected to compaction pressure which compacts the powder so that at least 80% basic density is obtained in the material. The compacted material is then machined. After machining, the compacted material is removed from the mold tool. The sintering stage is then carried out so that the final shape is obtained.

  • Patent number: 5972284
    Abstract: Solid, homogenous or porous, shaped bodies are formed from different powders such as metals and ceramics by preparation of an aqueous slurry of the powder, which slurry comprises a protein substance which is soluble in water at ambient temperatures and capable of forming an irreversible gel on heating to a temperature not exceeding 90.degree. C. The protein substance, for example albumin, is used in an amount sufficient for the formation of a gel. The slurry is formed into a body of the desired shape by methods such as molding, tapecasting or dropforming and heating to a temperature at least corresponding to the gelling temperature of the protein.

  • Patent number: 4534936
    Abstract: A method for removal of organic binders from powder compacts is disclosed in which the compact is heated while the weight change is monitored and controlled. The heating is regulated so that the removal rate of the binder is optimized. The removal time can be shortened without creating defects in the powder compact.
