Where Are We Going Today? • MP Enhancement Strategy in NX • Convergent Modeling: what’s in it for me? • Other NX Modeling Tools that help in this arena • 3DP Formats: STL vs. 3MF • Overview of Additive Manufacturing process in NX
NX Point Release Strategies • Siemens has been introducing new features in MP’s for a number of years now • NX11 released Aug-2016 • New Functionality in 11.0.1 (Feb-2017) o STEP 242 standard supported o Flatten 3D Faces to a Plane o Swept Volume o Make Solid o Combine o Convergent Modeling
Convergent Modeling in NX Facet Bodies: more than just a pretty face now • Convergent Modeling o New in Parasolid kernel 28.1 o Combines Facet Bodies and Boundary-Rep (b-rep) Modeling in the same toolset (NX) ▫ Reverse Engineering ▫ 3D Printing model prep ▫ Generative modeling tools o Speeds up design with facet models ▫ No translation/conversion/cleanup o Introduces the ‘Convergent Body’ type I ma g e : Sie me ns PL M
Convergent Modeling in NX Facet Bodies: more than just a pretty face now Par Participating F icipating Features atures : • Trim Body, Split Body • Booleans: Unite/Subtract/Intersect • Trim Sheet • Thicken • Divide Face • Extract Geometry* • Extrude • Link Geometry, Mirror Geometry • Extend Sheet • Pattern Geometry, Pattern Feature Mirror Feature • Make Solid (a new command), • Scale Body • Offset Surface and Offset Face *Convergent Behavior remains
Convergent Modeling in NX Facet Bodies: more than just a pretty face now • 2 Ways to Start Working With Faceted Geometry o Existing Facet Body in NX: Convert Facet Body feature o During Import STL/Scan Data
Convergent Modeling in NX Facet Bodies: more than just a pretty face now Since No Since Not All the F t All the Features W atures We Need Are Suppor Need Are Supported (y ed (yet) et) • Leverage Sketches more o Fillets, holes, chamfers, etc o Think 1 Step Ahead • Use Tool Solids/Subtracts • Sweep a surface and Trim • Reference Geometry o Extract/Create • We are still working with facet data in the end
STL Import & Modify Demo • Casting • Import � ConBod • Datums • Measurement • Split Body • Extrude new target bosses • Scale • Save as .JT
NX Tools to Accelerate Design • Dele Delete Body Body • Combine Combine • De Deviation viation Gauge Gauge • Multipatch Multipatch Alignment Alignment • Draf Draft Analysis t Analysis • Re Replace Fe Feature • Best Fit Alignment Best Fit Alignment • Check W Check Wall Thi ll Thickness kness • Divide F Divide Face ce • Point Set t int Set to P Point Set Alignment int Set Alignment
STL vs 3MF: RP Format Shifts • ST STL: been around for a while and most/all 3D Printers still use it. Requires post-processing in vendor specific software • 3MF 3MF: new format developed by o Richer data and smaller file size ▫ Materials and messhes ▫ Supports ▫ ‘Send to Printer’ o Zipped .XML packet. Win10 at the core o Major machine manufacturers and softwares involved Che c k it o ut: www.3mf.io
NX Additive Manufacturing • New License Type: Additive Manufacturing

NX Additive Manufacturing • Additive Manufacturing Analysis Tools o Wall Thickness checks (process appropriate?) o Overhang Angle (supports needed?) o Printable Volume (will it fit?) ▫ Uses MS 3D Printer drivers ▫ Custom lets you specify build volume o Wholly Enclosed Volume (water- tight?)
NX Additive Manufacturing General Workflow 1. Have your part(s) already modeled or imported as separate part files 2. Create a New ‘Additive Manufacturing’ part o Think Master Model assembly 3. Add the part into the Build Tray 4. Position in Build Tray 5. Right click on the component to add support 6. Right click on the Build Tray to edit machine parameters

NX Additive Manufacturing +Z is build direction
NX Additive Manufacturing SO … o We can work with STL/Scan Data faster now o We can modify STL files now ▫ Think Primitive and manage expectations o Custom Products workflows seem first to benefit ▫ Standard NX Model that is modified by custom STL data ▫ Medical, Footwear, Orthotics o NX can generate printer-ready 3DP files
