A device for producing microstructures, particularly microneedles and more particularly microneedle arrays, including a female mold that has, on a top side, at least one in particular conical depressed portion for producing a microstructure. The female mold is, for example, in the form of a silicone cap and is connected to a hollow cylinder in particular via a holding element. A plunger is disposed movably inside the hollow cylinder.

A cellulose ester composition is provided comprising at least one low hydroxyl content cellulose ester and at least one polymeric aliphatic polyester (PAP), and optionally at least one impact modifier and/or at least one monomeric plasticizer. Processes for producing the cellulose ester compositions as well as articles made using these compositions are also provided.

A blown film of soil biodegradable aliphatic polyesters produced primarily from diacid and diol monomers. The diacid monomers may be of any type including succinic acid, adipic acid, and hexanedioic acid. The diol monomer may be of any type including ethylene glycol, propanediol, butanediol, and hexanediol. Commercial aliphatic polyesters produced from diacid and diol monomers include polybutylene succinate (PBS), polybutylene adipate succinate (PBAS), and polybutylene adipate (PBA). Comonomers may also be added. Such comonomers include chemicals with a single carboxylic acid, hydroxy, or amine moiety, which act as chain terminators, chemicals with three or more carboxylic acid, epoxy, and/or hydroxy moieties which, act as branching agents.

The polymerizable composition for an optical material of the present invention includes a compound (A) represented by General Formula (a) and including two or more allyloxycarbonyl groups, at least one kind of radical polymerization initiator (B) selected from the group consisting of a peroxyketal-based radical polymerization initiator, a peroxymonocarbonate-based radical polymerization initiator, and a peroxyester-based radical polymerization initiator, and a modifier (C) selected from a polyether modified siloxane compound represented by General Formula (c1) or a polyol compound represented by General Formula (c2). ##STR00001##

A method for forming a prosthesis comprising a bone-like portion and a cartilage-like portion can comprise additively manufacturing a first positive mold in accordance with a portion of a first three-dimensional model of a portion of a bone. A first negative mold can be formed from the first positive mold. The bone-like portion can be created within the first negative mold. A second positive mold of the bone and a cartilage can be additively manufactured from a second three-dimensional model. A portion of the second three-dimensional model can correspond to a portion of the first three-dimensional model. A second negative mold can be formed from the second positive mold. The bone-like portion can be positioned in the second negative mold so that the second negative mold and the bone-like portion can define a cartilage space that can be filled with a material to form the cartilage-like portion of the prosthesis.

Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component present therein. Printed parts having piezoelectric properties may be formed using compositions comprising a plurality of piezoelectric particles located in a polymer matrix comprising a first polymer material and a sacrificial material that are immiscible with each other. The sacrificial material, which may comprise a second polymer material, may be removable from the first polymer material under specified conditions. The piezoelectric particles may remain substantially non-agglomerated when combined with the polymer matrix. The polymer matrix may be treated to remove the sacrificial material to introduce a plurality of pores. The compositions may have a form factor such as a composite filament, a composite pellet, a composite powder, or a composite paste. Additive manufacturing processes may comprise forming a printed part by depositing the compositions layer-by-layer.

A method of infusing, infiltrating or impregnating a three dimensional printed, free-form fabricated or additive manufactured object having pores or voids in or between particles or sheets of material from which the object is manufactured may include infusing the object with a thermoplastic material. The thermoplastic material may be a linear or branched semi-crystalline aliphatic polyester with a melting point of between 40° C. and 65° C. which may have a solidification/crystalisation point between 20° C. and 40° C., and which may be introduced under controlled conditions of temperature and pressure. The thermoplastic material may be caused to penetrate the object by immersing the object in the thermoplastic material and controlling the frequency and amplitude of pressure oscillation to ensure sufficient infusion into the object to penetrate the pores or voids by at least 10% and bond particles or sheets of material from which the object is manufactured.

A periodontal tissue regeneration inducer and an apparatus and a method for manufacturing the same are provided. The periodontal tissue regeneration inducer includes a sheet body formed of a flexible material, and a pattern layer having a pattern formed therein to facilitate bone formation or regeneration on a surface of the sheet body. Therefore, the periodontal tissue regeneration inducer and the apparatus and method for manufacturing the same have an advantage in that the bone formation or regeneration may be facilitated during implant surgery because the membrane sheet is composed of a polycaprolactone (PCL) material and a nanopattern is formed on a surface of the pattern layer.
