摘要:
The invention relates to a composite powder having microstructured particles, which can be obtained by a method in which large particles are joined to small particles, wherein the large particles have an average particle diameter in the range of 10 µm to 10 mm, the large particles comprise at least one polymer, the small particles are arranged on the surface of the large particles and/or are inhomogeneously distributed within the large particles, the small particles comprise a calcium salt, the small particles have an average particle size in the range of 0.01 µm to 1.0 mm, wherein the particles of the composite powder have an average particle size d50 in the range of 10 µm to less than 200 µm and the fine-grain fraction of the composite powder is less than 50 vol%. Preferred areas of application of the composite powder include the use thereof as an additive, in particular as a polymer additive, as an admixture or starting material for compounding, for compounding, for the production of components, for applications in medical technology and/or in microtechnology, and/or for the production of foamed objects. The invention therefore further relates to components that can be obtained by the selective laser sintering of a composition comprising a composite powder according to the invention, with the exception of implants for applications in the field of neurosurgery, oral, maxillary, facial, throat, nose, and ear surgery, and hand, foot, thoracic, rib, and shoulder surgery.
