1 3D PRINTING AND CONVERGENT MODELING IN NX Patrick Barrett

2 Patrick Barrett Who Am I Started using UG in 1996 Started Sherpa Design in 2001 Designed many things for many different industries o Castings, tooling, fixtures o Consumer electronics o OptoMechanical and Semiconductor Enjoy teaching and learning NX o Developed our own NX Training classes 2005 o Dove into NX CAM and CMM with our shop

3 Proudest Teaching of 2017

4 Who Is Applied CAx? Joint venture of two respected engineering companies providing the best support for Siemens PLM Software. NX CAD NX CAM Teamcenter 15 engineers 2 veteran Teamcenter architects Training for NX CAD/CAM, Teamcenter Reverse Engineering Industrial Design CAM/CMM R&D machining NX CAE FEMAP LS-DYNA STAR CCM+ 5 engineers (PhD s, ME s, PE s) FEA consultants CFD consultants Training for FEMAP & NX Nastran Training for LS-DYNA Implicit & Explicit

5 Why We re Sought After Focused on the technical side of products Owned by two experienced engineers Develop and deliver customized training Co-owner Patrick Barrett Mechanical Engineer Run R&D machine shop 30-to-3 employee ratio of Tech-to-Sales We use the tools ourselves every day Co-owner George Laird Mechanical Engineer

6 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

7 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 (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

8 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 Image: Siemens PLM

9 Convergent Modeling in NX Facet Bodies: more than just a pretty face now Participating Features : Booleans: Unite/Subtract/Intersect Thicken Extract Geometry* Link Geometry, Mirror Geometry Pattern Geometry, Pattern Feature Mirror Feature Scale Body *Convergent Behavior remains Trim Body, Split Body Trim Sheet Divide Face Extrude Extend Sheet Make Solid (a new command), Offset Surface and Offset Face

10 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

11 Convergent Modeling in NX Facet Bodies: more than just a pretty face now Since Not All the Features We Need Are Supported (yet) 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

12 STL Import & Modify Demo Casting Import ConBod Datums Measurement Split Body Extrude new target bosses Scale Save as.jt

13 NX Tools to Accelerate Design Delete Body Combine Deviation Gauge Multipatch Alignment Draft Analysis Replace Feature Best Fit Alignment Check Wall Thickness Divide Face Point Set to Point Set Alignment

14 STL vs 3MF: RP Format Shifts STL: been around for a while and most/all 3D Printers still use it. Requires post-processing in vendor specific software 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 Check it out:

15 NX Additive Manufacturing New License Type: Additive Manufacturing

16 NX Additive Manufacturing PREREQUISITES FOR PRINT 3D IN NX 11 O/S WIN8.1 OR HIGHER, WIN10 Recommended NEED TO CONFIG FOR THE PRINTER YOU HAVE Win10 has preloaded drivers for some mainstream/hobby printers

17 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 (watertight?)

18 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

20 NX Additive Manufacturing +Z is build direction

21 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
