example 1

[0032] Modeling material : The molding material A is polycarbonate resin. A specific exemplary polycarbonate resin is Lexan(R) HF 1110 (available from General Electric Plastics). This resin has a heat deflection temperature of 156°C and a melt flow at 300°C under a load of 1.2kg in the range of 20-30 gms / 10min. Polycarbonate resin was successfully extruded from a liquefier at about 320°C into a build chamber at about 135°C.

[0033] support material : The support material B is a resin comprising a mixture of polyphenylene ether and polyolefin, such as high-impact polystyrene. The desired weight percent range is about 50-90% polyphenylene ether and about 10-50% polyolefin. A specific example of a resin is a mixture of 75 wt% Noryl(R) 731 polyphenylene ether and 25 wt% Noryl(R) N300X high impact polystyrene (each available from General Electric Plastics). This resin has a heat deflection temperature of 178°C and a melt flow similar to molding materials. Extruded from a l...

example 2

[0035] Modeling material : The molding material A is polycarbonate / acrylonitrile-butadiene-styrene resin. To provide the material with the enhanced strength and toughness of polycarbonate, the resin should contain at least about 50% by weight polycarbonate. A particularly preferred polycarbonate / acrylonitrile-butadiene-styrene resin is Cycoloy(R) C1110HF (available from General Electric Plastics). This resin has a heat deflection temperature of 143°C and a melt flow at 280°C under a load of 1.2kg in the range of 10-20 gms / 10min. The polycarbonate / acrylonitrile-butadiene-styrene resin was successfully extruded from a liquefier at about 320°C into a build chamber at about 110°C.

[0036] support material : The support material B is a resin comprising a mixture of polyphenylene ether and polyolefin, such as high-impact polystyrene. The desired weight percent range is about 40-80% polyphenylene ether and about 20-60% polyolefin. A specific example of a resin is Noryl(R) 731...

example 3

[0038] Modeling material : The molding material A is polyphenylsulfone resin. An example of a specific polyphenylsulfone resin is Radel(R) R 5600 NT (available from BP Amoco). This polyphenylsulfone resin has a heat deflection temperature of 236°C and a melt flow at 400°C under a load of 1.2kg in the range of 20-30 gms / 10min. Polyphenylsulfone resin was successfully extruded from a liquefier at about 400°C into a build chamber at about 200°C.

[0039] support material : The support material B is a resin comprising a mixture of polyphenylsulfone and amorphous polyamide. The material may further comprise polysulfone. The desired weight percent range is a mixture of about 60-90 wt % polyphenylsulfone and about 10-40 wt % amorphous polyamide, or about 60-90 wt % polyphenylsulfone, about 1-40 wt % polysulfone and about 10 wt % - 40% by weight of a mixture of amorphous polyamides. A specific exemplary resin is 50 wt% Radel® R 5600 NT polyphenylsulfone (available from BP Amoc...

Abstract

Disclosed is a high-performance thermoplastic material used to build a three-dimensional model and its support by using fusion deposition modeling technology. The molding material used to build the model (26) consists of a thermoplastic resin with a heat deflection temperature higher than 120°C. Amorphous thermoplastic resins that can be self-laminated and weakly bonded to modeling materials have a heat deflection temperature similar to that of modeling materials, and a tensile strength between 34-83MPa (5000psi-12000psi), which is used to build support structures ( 28) Support material. In a preferred embodiment, the thermoplastic resin constituting the support material is selected from a mixture of polyphenylene ether and polyolefin, a mixture of polyphenylsulfone and amorphous polyamide, a mixture of polyphenylsulfone and polysulfone, and amorphous polyamide. group.

Description

technical field [0001] The present invention relates to the production of three-dimensional objects using additive process modeling techniques. More particularly, the invention relates to depositing a first curable material in a predetermined pattern to form a three-dimensional object while depositing a second curable material to provide a support structure for the three-dimensional object being built. Background technique [0002] The additive method modeling machine makes a three-dimensional model according to the design data provided by the computer-aided design (CAD) system and accumulates the modeling medium. The three-dimensional model is used to provide functions including aesthetic judgment, inspection of mathematical CAD models, forming hard tooling, study of interference and space allocation, and testing of functions. One technique is to pile up curable modeling materials in a predetermined pattern according to the design data provided by the CAD system, and accum...
