Abstract
The present invention relates to a process for producing a Pharmaceutical dosage form by powder bed fusion selective laser 3-dimensional printing, in particular selective laser sintering 3-dimensional printing (SLS), and a pharmaceutical dosage form manufactured by that process.
Claims14
Process for producing a pharmaceutical dosage form by powder bed fusion selective laser 3-dimensional printing, comprising the steps of
- (a) providing a first sinter powder, essentially consisting of an active pharmaceutical ingredient or essentially consisting of a mixture of at least two active pharmaceutical ingredients, in a first reservoir platform,
- (b) providing a second sinter powder, comprising an excipient, wherein said excipient absorbs electromagnetic radiation at a wavelength emitted by the laser, in a second reservoir platform, and
- (c) operating a selective laser sintering apparatus that fuses layers of the first and second sinter powder to produce the pharmaceutical dosage form.
