Abstract: A semi-crystalline blended polymer useful for additive manufacturing is comprised of an amorphous thermoplastic polymer and a thermoplastic semi-crystalline polymer, each of the polymers being essentially miscible in the other and being blended at a weight ratio of amorphous polymer/semi-crystalline polymer of greater that 1 to about 20. The semi-crystalline blended polymer displays a DSC melt peak enthalpy of at least about 3 joules/g. The semi-crystalline polymer may be made by blending the aforementioned polymers at the weight ratio and subject to heating between the melt temperature of the semi-crystalline polymer and the glass transition temperature of the amorphous polymer. The semi-crystalline blended polymer may revert to essentially an amorphous polymer when additive manufactured by fusing layers of said polymer powders together.

Abstract: The present invention utilizes 3D printing technology, specifically fused filament fabrication (FFF) 3D printing, to produce solid dosage forms, such as pharmaceutical tablets. The production process utilizes novel printing filaments, typically on a spool, which contain the active ingredient. Such active-containing filaments have proved to be extremely robust and the principles outlined in the present disclosure provide access to a variety of viable formulations directly from a 3D printer. This, for the first time, affords a viable means for the in situ (e.g. within a pharmacy) 3D printing of personalized medicines tailored to a patient's needs. The invention also relates to purpose-built software for operating the printing apparatus, as well as local, national and global systems for monitoring the real time operation of a plurality of printing apparati to enable facile detection of malfunctions, thereby making regulatory approval viable and facilitating regulatory compliance.

Abstract: A filament conditioning system or method for FDM 3D printing uses a filament tube with vent holes extending through a sidewall of the filament tube to a filament passthrough in the filament tube. A desiccant barrier contains the filament tube and includes vent holes through a sidewall of the desiccant barrier, and a cover contains the desiccant barrier and a desiccant in a space between the cover and the desiccant barrier. A heating element and temperature sensor may adjacent the filament tube within the desiccant barrier to heat a filament in the filament passthrough. The filament tube, the desiccant barrier, and the cover may be coaxial tubes held together with end caps, the end caps also providing vent holes and openings for electrical leads.
