3D scanning of parts for AM applications
Despite the numerous advantages of using 3D scanning in the additive manufacturing process , there are also some associated challenges such as scanning large and heavy parts . Recognizing the issue , certain new technologies ( such as the Quantum Max portable coordinate measuring machine ) offer larger reach to provide more comfortable articulation for better extension over and around large objects .
When combined with the FARO ® 8-Axis Max Rotary Worktable , a modular component that can be used with any FaroArm , the need to relocate or reposition the scanning device is nearly eliminated . Traditionally , technicians would have to scan a large part one section at a time and then move the scanner to the next section , but this could result in inaccurate data .
Another challenge associated with traditional 3D scanners is that they often have difficulty scanning parts that are dark , shiny or reflective . In these instances , technicians will spray the part with powder to achieve a matte finish in order to obtain

an accurate scan , but this may become an obsolete procedure due to the introduction of optically superior blue-laser technology .
FARO ’ s Quantum Max ScanArm features three purpose-built , hot-swappable Laser Line Probes ( LLPs ). It offers capabilities such as rapid prototyping , reverse engineering and 3D modelling of free-form surfaces . The blue-laser technology enables scanning of challenging surfaces , including those that are dark or reflective , simplifying the process
prior to additive manufacturing applications . “ Complicated software used to convert scans for printing was another challenge for additive manufacturers . However , today even the most sophisticated software programs are becoming more user-friendly . For example , FARO RevEng™ software allows users to accurately capture and more easily edit meshes for the creation of models for 3D printing ,” explained the manufacturer .
“ Using the software in combination with 3D scanning products allows data ranging from high-resolution colour point clouds to simple meshes to be transformed into detailed meshes , providing more insight into the design and composition , as well as visual differentiation between materials and textures . The intuitive user interface visually displays all the tools within a single screen , facilitating easy manipulation and customisation of the 3D object to meet specific design requirements ,” it added . n

Smart and automated shot blast solutions
When it comes to shot blasting applications , Rösler offers equipment concepts for indexing continuous flow manufacturing operations . One such machine is its compact RWK 6 / 12-2 swing chamber shot blast machine . Equipped with automated workpiece handling , it can be integrated into linked manufacturing lines , requiring very little space . The furnished digitisation software package from Rösler Smart Solutions provides complete process and cost transparency and minimises overall personnel requirements .
“ For shot blasting , the Rösler RWK 6 / 12-2 swing chamber shot blast machine with automated workpiece handling can be used for all kinds of shot blast applications such as surface cleaning ; de-sanding and descaling ; surface homogenisation and sophisticated shotpeening operations . The workpieces treated in this machine include all kinds of castings and forgings , machined components , welded sheetmetal parts and technical springs ,” explained Rösler .
With its small footprint , the compact shotblast machine requires very little space when integrated into linked manufacturing lines . Specially prepared interfaces in the machine controls facilitate quick connection to higherlevel production control systems . A standard industrial robot handles the workpieces by placing them into the blast chamber and
removing them after completion of the blast cycle ( requiring very little programming effort ). A special clamping mechanism in the blast chamber holds the workpieces in place during the shot blast process .
“ In its standard version , the RWK 6 / 12-2 can handle workpieces with diameters of up to 600mm and lengths of up to 1,200mm . The clever dual-chamber design enables workpiece loading / unloading in one chamber , while the shot blast process takes place in the second chamber . This practically eliminates any unproductive times . The machine is equipped with

two Gamma G turbines , which guarantee short cycle times and energy-saving operation . Another key characteristic of the RWK 6 / 12-2 shot blast machine is its wear-resistant design . The blast chamber is made from manganese steel and is additionally lined with easily replaceable wear plates made from a low-wear material ,” added the manufacturer .
Digitisation modules from Rösler Smart
The RWK 6 / 12-2 with automatic workpiece handling .
Solutions allow the implementation of automation concepts that go beyond automatic workpiece handling . The software package is designed to lower the operational costs and personnel requirements through intelligent process and equipment control . At its centre is the active monitoring and analysis of various machine components and process parameters . Any deviations from the specified process parameters and malfunctions are displayed so that corrective action can be quickly taken . n
