02 Print2mold: the user

02 Print2mold: the user can order his wear-resistant special part online in the appropriate lubrication-free and maintenance-free iglidur material AUTIOMATION DIN EN45545 for rail vehicles. The 3D printing of polymer components for trains, for example the plain bearings for the opening mechanisms of the doors is made possible. igus expands its 3D printing service In order to facilitate the 3D printing breakthrough in the industry, igus also offers a 3D printing service. The customer does not have to invest in their own 3D printer, but merely provide the computeraided design (CAD) file of a wear-resistant part. If this is not available, igus can digitise the component with a 3D scanner. Alternatively, the customer can use the free igus configurator to create a 3D model of his gear or plain bearing, rack or roller. The next step: the customer chooses a printing material that is suitable for his application. An online tool offers an orientation that uses latest findings from the test lab. Then printing begins. The factory features Fused Deposition Modeling (FDM) printers as well as Selective Laser Due to the high demand, we are further expanding our 3D printing service for wear-resistant special solutions with new laser sintering printers. Tom Krause, Business Division Manager Additive Manufacturing at igus Sintering (SLS) equipment. In the FDM process, molten polymer flows through a nozzle. In the laser sintering process, however, a laser melts polymer powder. Both processes can be used to produce unique pieces and batches of up to 5000 pieces cost-effectively. Bridging the gap: print2mold 3D printing is not suitable for all jobs. Many customers want materials that until now can only be processed by injection moulding or bar stock. Also for prototypes and small quantities. The problem: time-consuming and expensive special injection moulding tools are needed. The solution: igus builds a bridge between 3D printing and injection moulding. The company produces the moulds in additive manufacturing under the name of print2mold. “With print2mold, we are able to produce injection moulds within a day and reduce costs by up to 80 % compared to milled or eroded tools,” says Krause. “Thanks to this method, it is also possible to implement very fine details and complex structures.” Future music And what can we expect from the future? “An exciting question is the economic production of multi-material components for the introduction of even more targeted material properties,” says Tom Krause. “For example, hard-soft combinations have already been implemented. For scalability, however, technological advances are needed. igus is working hard to enable all 55 existing iglidur ma terials for 3D printing.” Photos: lead/ornaments adobe.istock, others Igus 16 WORLD OF INDUSTRIES 1/2020

More performance in 3D image processing Image processing is becoming increasingly important in industry. We present you a new programmable 3D camera, that opens up new possibilities to develop solutions utilizing the values of 3D vision. This camera offers full flexibility for detection, as well as 2D and 3D inspection, of moving objects, thereby allowing tailored solutions for a wide range of image processing applications. Author: Nina Hammerin, 3D Vision Product Manager, Sick IVP, Linköping, Sweden The TriSpectorP1000 is a compact, programmable 3D camera; its design combines laser illumination and camera optics in a single housing, creating a geometrically stable and identical measurement set-up in every application, and convenient integration of the sensor into the machine environment. There are three different field-of-view variants, making it possible to inspect objects from a few millimeters up to half a meter, thus enabling optimal implementation of the task. Image processing and analysis are fully integrated into the TriSpectorP1000 design. The high-resolution shape data measured by the factory-calibrated 3D camera is given millimeter values, and the processing results can be communicated directly from the device. The possibility to program the TriSpectorP1000 in the Sick App- Space development environment enables machine builders and integrators to implement tailor-made 3D vision solutions, including a web-based operator interface. For every individual application, the software modules of Sick AppSpace enables users to develop perfect-fit 3D image processing scripts and user interfaces, and to share these with their customers. Prepared for challenging 3D inspection tasks Whether it is the high variance of parts, demanding object properties, fast processes, adverse ambient conditions, or stringent requirements for measurement accuracy, the programmable camera Freedom for the development The common programming platform Sick AppSpace eco-system for different sensor technologies consists of three areas: Hardware, in the form of programmable devices and sensors, the AppStudio software module for application development and the AppManager for the implementation and management of SensorApps in the field. Within the Sick AppSpace, the App- Pool, a secure cloud service, provides SensorApps from Sick and its integration partners through a reliable platform. is the ideal choice for meeting even very complex requirements of 3D inspection in an uncomplicated and individualized manner. In terms of hardware, this 3D camera is designed to be consistent with industrial stand-alone usage: It has a space-saving and mechanically rugged anodized aluminum housing with enclosure rating IP 67, and is available with front screens made from either glass or plastic suitable for use with food. For detection as well as 3D, 2D and profile inspection, the Tri- SpectorP1000 acquires real shape data. This data is independent of the color, contrast and surface properties of the objects as well as background influences, and even factors related to ambient light. Results, for example picking coordinates, product volume and dimensions or the verified presence of a component, can be output via digital outputs and via the gigabit Ethernet interface. Image processing scripts can be programmed with the functions in the Sick Algorithm API or with the Halcon library – a corresponding runtime license comes with the TriSpectorP1000 3D camera. Inline inspection – flexible and tailor-made The TriSpectorP1000 can be used as an inline inspection system in a wide range of industries and applications, including volume and dimension measurement of objects, visual guidance of pick-andplace robots, object counting and position checks, contour checks and profile verification, and anywhere efficient inspection of 3D object geometries is required. Stamped or engraved OCR characters can also be read and analyzed. Example: When gripping, sorting and packaging food with pickand-place robots, the 3D camera detects the shape of each individual product and outputs the picking position, including the true height, as well as the rotation of every product. In this way, the robot can safely grab OK products and put them in primary packages while products that do not meet the picking criteria are left on the belt. At the same time, the camera can deliver quality information on the products, which makes it possible to inspect the manu facturing, transport and packaging processes and correct them if necessary. In summary, the programmable 3D camera enables a vast variety of tailored solutions for flexible automation, far beyond the examples mentioned above.
