Abstract:
PROBLEM TO BE SOLVED: To provide a device and method for continuous and efficient maintenance of a three-dimensional printer.SOLUTION: There is disclosed a device capable of forming a three-dimensional object from a continuous layer printed by an inkjet printing head. A test pattern 129 is used to line up the printing head, which consists of a reference line 135 and a test line 136 being alternate and in parallel with and orthogonal to a first travel axis. Test is carried out by using a line having test bars intermittently arranged around a central test bar. The device is also provided with a printing head cleaner. The test pattern 129 is prepared by an alignment sensor system 132, and is analyzed by a first Fourier transformer (FFT).
Abstract:
PROBLEM TO BE SOLVED: To perform the automatic designing economically with rapidity and high reliability by providing a step to partially change stored sets of data for defining the solid part of the shape of an object and coverting the solid part into a part consisting of a region where it is cured or a region where it is maintained in an uncured state according to each of exposure levels. SOLUTION: When a design displayed on the output image screen of a computer is satisfactory, parts are manufactured and when the design needs to be corrected, a change is repeatedly made through the computer. In this case, a pattern for stimulating each of many superposed thin layers 30a, 30b, 30c of a transferable fluid medium 22 is changed partially in a data processing step 25. Further, alteration data for converting the solid part to the part comprising a region where it is cured according to a first exposure level and a region where it is cured according to a second lower exposure level or a region where it is maintained in an uncured state while each of the thin layers 30a, 30b, 30c is initially formed, is created.
