Equipment for laminating and manufacturing 3D objects

摘要

The present invention relates to an apparatus for laminating and manufacturing a three-dimensional object in a powder bed fusion bonding method. The apparatus (20) laterally views the modeling space (1), at least one energy source (5), the modeling area (4) having the modeling space platform (6), and the modeling space platform (6). Includes the surrounding modeling space container (9). The modeling space platform (6) has an upper side (12) facing the powder (2) and a lower side (13) not facing the powder. The upper side (12) of the build space platform (6) contains a material having a thermal conductivity of at least 20 W / (m · K), and the lower side (13) of the build space platform (6) is the highest. Includes materials with a thermal conductivity of 0.5 W / (m · K). The contact area of the upper side (12) of the modeling space platform (6) with the powder (2) or the refrigerant is increased by at least 20% as compared with the plane of the modeling space platform (6).
