A method of forming a three-dimensional object, wherein said three-dimensional object is an insert for use between a helmet and a human body, is described. The method may use a polymerizable liquid, or resin, useful for the production by additive manufacturing of a three-dimensional object, comprising a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from said first component.

A method of modifying a deformable substrate that includes depositing a sessile liquid droplet on a first surface of a deformable substrate, the sessile liquid droplet forming a deformed region in the first surface of the deformable substrate, the deformed region having a recess and a perimeter rim, the recess extending toward a second surface of the deformable substrate, and the perimeter rim extending away from the second surface of the deformable substrate and curing the deformable substrate, thereby increasing an elastic modulus of the deformable substrate such that upon removal of the sessile liquid droplet, the deformed region remains in the first surface of the deformable substrate.

A surface treatment method of an object, including the following steps immersion of the object in a solution containing an acid or a mixture of acids, and having a pH between 0 and 6, so as to impregnate the surface of the object, removal of the object from the acid solution, and heating of the object to a temperature between 50 C. and the melting temperature of the object, until the required gloss and roughness surface properties are obtained, the method is particularly but not exclusively applicable to objects derived from additive manufacturing techniques.

The invention is a novel method of creating three-dimensional foam insulative objects formed by applying liquid nail polish or a solvent to polystyrene foam, thus softening the foam and allowing a person to mold the foam into a desired shape before it hardens. The products of the present invention have applications in venues including the insulation of buildings from temperature and from impacts. The use of a nail polish allows a user to create building materials with customizable shapes and colors.

In a coating method example, a coating is formed on a part precursor by blasting the part precursor with a blast medium. The blast medium includes blasting beads and a coating agent. The part precursor is formed from a polymeric build material, and a hardness of the blasting beads is greater than a hardness of the polymeric build material.

The invention relates to a process and an apparatus for chemical smoothing of a plastic part (10) produced by selective layerwise consolidation of a construction material. The process comprises the steps of: temperature-controlling the plastic part to a first temperature; temperature-controlling solvent vapour (8) comprising a solvent to a second temperature; subjecting the plastic part (10) to the solvent vapour (8) temperature-controlled to the second temperature for a particular duration, wherein the subjecting of the plastic part (10) to the solvent vapour (8) has the result that an outer layer of the plastic part (10) is liquefied; and discharging at least a portion of the solvent vapour (8) after the particular duration, wherein the plastic part (10) is stationary from commencement of the temperature-controlling of the plastic part until termination of the discharging of the solvent vapour (8).

The invention relates to a method and to a device for stabilizing precursor fibers for the production of carbon fibers. In the method, precursor fibers are first heated to a first temperature and held at the temperature for a predefined duration. Subsequently, the precursor fibers are heated to at least one second temperature, which is higher than the first temperature, and held at said temperature for a predefined duration. During each heating and between the heating steps, the precursor fibers are in a gas atmosphere having a negative pressure in the range between 12 mbar and 300 mbar and having an oxygen partial pressure of 2.5 to 63 mbar. The device has at least one evacuable, elongate vacuum chamber for feeding the precursor fibers through, at least two lock units and at least one heating unit. At least one lock unit is used for the sealed insertion of precursor fibers into the at least one vacuum chamber, while at least one other lock unit is used for the sealed removal of precursor fibers from the at least one vacuum chamber. The heating unit has at least two individually controllable heating elements, which are suitable for heating the at least one vacuum chamber to at least two different temperatures in heating zones which are adjacent in the longitudinal direction.

The invention relates to additively manufactured dental devices comprised of a denture base and at least one removable bracing body joined at specific locations to the denture base. The invention also relates to methods of using these additively manufactured dental devices in the fabrication of dental prostheses.

The present invention is directed to a new concept for an internal metallic tank of large-scale high-pressure gasholder in which pluralities of internal tanks have been accumulated like a honeycomb structure and for the manufacturing processes of the internal metallic tank.

Methods and systems for treating an additively manufactured components are described. The methods include placing the additively manufactured component into a treatment chamber within a treatment vessel, performing a first treatment operation on the additively manufactured component within the treatment vessel, using a first treatment material, and performing a second treatment operation on the additively manufactured component within the treatment vessel, using a second treatment material, wherein the first treatment material is a gaseous treatment material and the second treatment material is a liquid treatment material.
