Abstract: The present disclosure relates to a moldless three-dimensional printing method and apparatus for applying the method. The method comprises intermittently feeding a continuous sheet material into a build chamber, and maintaining a determined tension of the continuous sheet material. The method comprises ablating predetermined areas corresponding to internal part features of a layer of a manufactured object in a section of the sheet material. The method comprises positioning the section of the sheet material on top of a previous section of the sheet material. The method comprises bonding the section of sheet material to the previous section of the sheet material. The bonding includes applying a determined pressure and at least one determined temperature. The method comprises ablating external contours of the bonded section of the sheet material. The method further comprises controlling an ablation temperature, the determined pressure and the at least one determined temperature of the bonding.
