The invention relates to a method for producing an implant by means of a composite powder having microstructured particles having inhibiting calcium carbonate, wherein the composite powder is obtained by a method in that large polymer particles are joined to small calcium carbonate particles, wherein the calcium carbonate particles are obtained by a method in that calcium carbonate particles are coated with a composition which, in each case based on the total weight thereof, comprises a mixture of at least 0.1 wt% of at least one calcium complexing agent and/or at least one conjugated base which is an alkaline metal or calcium salt of a weak acid, together with at least 0.1 wt% of at least one weak acid.
