The present invention relates to a solid form, particularly to a 3D-printed immediate release solid dosage form (e.g. based on a pharmaceutical, nutraceutical, or food supplement composition). To overcome some of the solubility and disintegration problems inherited by 3D-printed solid dosage forms, the solid form comprises one or more channels, generally in the form of tubular passages or grooves, through the body of the solid form or the surface thereof.

The invention relates to a process (100) for manufacturing an object (1) made of thermoplastic polymer composite from at least two parts (10) made of thermoplastic polymer composite, said thermoplastic polymer composite comprising a fibrous reinforcement and a thermoplastic polymer matrix, said process comprising the steps of: arranging (120) the two parts (10) made of thermoplastic polymer composite adjacently or overlapping at an assembly interface zone (11), and heating (130) to melt the thermoplastic polymer matrix at said assembly interface zone (11), so as to form an object (1) made of thermoplastic polymer composite comprising a welded interface (12).

Materials and methods for cell-mimetics having mechanical properties of biological neural axons are provided. A cell-mimetic device includes an array of fibers comprised of hexanediol diacrylate (HDDA) or an HDDA derivative, and at least one derivative of polyethylene glycol (PEG) selected from the group consisting of: PEG-acrylate, PEG-diacrylate, and any multi-arm PEG-acrylate.

A composite oil pan for a work vehicle engine and a method of forming the composite engine oil pan include forming a sheet of metal into a first pan and open molding a fiber-reinforced polymer resin onto the first pan forming a second pan. The first pan has a first bottom wall and first peripheral walls extending from edges of the first bottom wall to define a sump, the first peripheral walls terminating in a first peripheral flange. The second pan has a second bottom wall and second peripheral walls abutting the first bottom wall and the first peripheral walls, the second peripheral walls terminating in a second peripheral flange. The first pan defines a thin metal structure with an inner surface extending across the first bottom wall, first peripheral walls and first peripheral flange; the second pan reinforces the first pan without abutting the inner surface.

The present invention discloses a nucleic acids extraction system and method based on a 3D-printed microdevice, and belongs to the technical field of nucleic acids extraction. The nucleic acids extraction system is a monomer 3D-printed microdevice or a 3D-printed microdevice prepared by 3D printing technologies, the monomer 3D-printed microdevice comprises a nucleic acids binding region and a handle region, and the 3D-printed microdevice is composed of more than two monomer 3D-printed microdevices through a joining region; and the nucleic acids binding region is made of photosensitive resin or thermoplastic. An extraction method for the nucleic acids extraction system based on a 3D-printed microdevice is used to bind, clean and elute nucleic acids by moving the monomer 3D-printed microdevice or the 3D-printed microdevice among a solution containing target nucleic acids, a washing buffer and an elution buffer.

The present invention provides a resin composition for optical shaping that, with its low viscosity, enables easy stereolithographical fabrication of an object, and that can produce an object having desirable toughness and desirable water resistance, particularly for dental mouthpieces and denture base materials. The present invention relates to a resin composition for optical shaping comprising a urethanized (meth)acrylic compound (A) and a photopolymerization initiator (B), the urethanized (meth)acrylic compound (A) being a (meth)acrylate containing at least one polyol moiety and a urethane bond per molecule, said at least one polyol moiety being selected from the group consisting of a polyester, a polycarbonate, a polyurethane, and a polyether each having a structure derived from a C4 to C18 aliphatic chain diol unit (a) having a branched structure.
