摘要:
The invention is describing an intrauterine delivery system comprising non-steroidal anti-inflammatory (NSAID) and a progestogenic compound, containing anti-inflammatory active compound in the frame material and that the progestogenic compound is contained in a silicon based reservoir attached to the frame, wherein the frame consist of a thermoplastic material. A further object of the invention is to fabricate drug-containing T-intrauterine systems (I US) with the drug incorporated within the entire backbone of the medical device by using 3D printing technique, based on fused deposition modelling (FDM™). Indomethacin was used to prepare drug-loaded poly-caprolactone (PCL)-based filaments with different drug contents 5—40 wt%, namely 5%, 15% and 30% wt%:of Indomethacin.

摘要:
A support material for use in an additive manufacturing system (10) to print a support structure (32) for a three-dimensional part. The support material includes a base resin that is substantially miscible with a part material used to print the three-dimensional part, and has a glass transition temperature within about 10°C of a glass transition temperature of the part material. The support material also includes a dispersed resin that is substantially immiscible with the base resin, where the base resin and the dispersed resin are each thermally stable for use in the additive manufacturing system (10) in coordination with the part material.
摘要:
A method of forming a golf ball includes forming a core using a 3D printer, and molding a cover in a surrounding position over the core through at least one of compression molding and injection molding. The core may be formed by printing a first core portion, printing a second core portion, and fusing the first core portion with the second core portion to form the core. Each of the first and second core portions may respectively include a plurality of concentric shells that are sequentially constructed.
摘要:
A fabrication process and apparatus for producing three-dimensional objects by depositing a first polymer layer, printing a first ink layer on to the first polymer layer, depositing a second polymer layer on to the first ink layer, and printing a second ink layer on to the second polymer layer. The deposition and printing steps may be repeated until a three-dimensional object is formed. The inks used to form at least one of the first and second ink layers may include dyes or pigments so that the three-dimensional object may be a colored three-dimensional object.
