Increased inter-layer bonding in 3d printing

摘要: Inter-layer bonding in objects manufactured by 3D printing techniques is improved one or more targeted heat sources (THSs) that preheat a portion of existing object material before additional added to the object. Printing also improved, optimized calibrated pre- post-heating area. THS elements may be fixed, mobile, combination thereof apply areas. A integrated as an add-on printer. controller use printer information, such current direction future printing, select THSs and perform other operations, setting energy levels, aiming, moving, etc. Properties, e.g., strength, printed with interlayer may, for example, several multiples better than same without bonding.
