The invention relates to an implant comprising a composite powder having microstructured particles, 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 from 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 distributed non-homogenously within the large particles, the small particles comprise a calcium salt, the small particles have an average particle size in the range from 0.01 µm to 1.0 mm, wherein the particles of the composite powder have an average particle size (d50) in the range from 10 µm to less than 200 µm, and the fine-grain proportion of the composite powder is less than 50% by volume. The subject of the invention is therefore further implants obtained by selective laser sintering of a composition comprising a composite powder, in particular as an implant for applications in the area of neuro-surgery, oral, jaw, face, neck and ear surgery, and in hand, foot, thorax, rib, and shoulder surgery.
