Abstract
Moldings can be produced from a polymer powder containing at least one block polyetheramide containing an oligoamide dicarboxylic acid and a polyetheramine; wherein the powder is suitable for use in a layer-by-layer process in which regions of a powder layer are selectively melted via introduction of electromagnetic energy.
Claims47
A polymer powder, comprising:
- at least one block polyetheramide comprising an oligoamide dicarboxylic acid and a polyetheramine;
- wherein said powder is suitable for use in a layer-by-layer process in which regions of a powder layer are selectively melted via introduction of electromagnetic energy.
A process for production of a molding, comprising:
- via a layer-by-layer process selectively melting regions of a respective powder layer of a powder by introduction of electromagnetic energy,
- wherein the selectivity is achieved via application of a susceptor, an inhibitor, an absorber, or a mask,
- wherein said powder comprises
- at least one block polyetheramide comprising an oligoamide dicarboxylic acid
- and a polyetheramine.
