By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-From Washington,D.C.,NewsRx journali sts report that a patent application by the inventor SUZUKI,Takanori (CHINO-SHI,JP),filed on August 16,2023,was made available online on February 22,2024.No assignee for this patent application has been made.News editors obtained the following quote from the background information suppli ed by the inventors:" "The present disclosure relates to a three-dimensional-object printing apparatus ."A three-dimensional-object printing apparatus that performs printing by an ink jet method on the surface of a three-dimensional workpiece is known.For example,JP-A-2017-19183 discloses a printing apparatus that performs printing while ch anging the position of the print head relative to the print target by using an a rticulated robot."In general,the print head is electrically coupled to a drive substrate that ge nerates drive signals for driving the print head.JP-A-2017-19183 does not refer to the drive substrate."When the position of the drive substrate is fixed relative to the base portion of the articulated robot,the wiring for electrically coupling the print head and the drive substrate needs to be laid out along the arm of the articulated robo t.In this case,the layout of the wiring is complicated.In addition,since the wiring is long,signals from the drive substrate can attenuate,and picked-up n oise can affect the signals.Hence,it is conceivable to position the drive subs trate at the distal end of the articulated robot together with the print head to shorten the wiring.
