Document Type and Number:
WIPO Patent Application WO/2024/063138
Kind Code:
A1
Abstract:
Provided are a three-dimensional shaped object obtained from a crystalline thermoplastic resin and having excellent mechanical properties and a method for producing the three-dimensional shaped object. The three-dimensional shaped object is one obtained by a fused filament fabrication method from a filament comprising a crystalline thermoplastic resin, and has a void content of 5% or less. The method for producing the three-dimensional shaped object comprises using a 3D printer to form layers from a filament comprising a crystalline thermoplastic resin by the fused filament fabrication method to thereby form a three-dimensional shaped object. It is preferable that the set ejection-amount value to be input to the 3D printer or to data processing software for the 3D printer be larger than 100%.
