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’ typeImage: Siemens PLM
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
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 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
STL Import & Modify Demo
• Casting
• Import ConBod
• Datums
• Measurement
• Split Body
• Extrude new target bosses
• Scale
• Save as .JT
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
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

NX Additive Manufacturing
• New License Type: Additive Manufacturing
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
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 Workflow1. 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

+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
