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)
• STEP 242 standard supported
• Flatten 3D Faces to a Plane
• Swept Volume
• Make Solid
• Combine
• Convergent Modeling

Convergent Modeling in NX

Facet Bodies: more than just a pretty face now

• Convergent Modeling
• New in Parasolid kernel 28.1
• Combines Facet Bodies and Boundary-Rep (b-rep)

Modeling in the same toolset (NX)

▫ Reverse Engineering ▫ 3D Printing model prep ▫ Generative modeling tools

• Speeds up design with facet models

▫ No translation/conversion/cleanup

• Introduces the ‘Convergent Body’ type

Facet Bodies: more than just a pretty face now

Par Participating F icipating Features atures :

• 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
• Existing Facet Body in NX: Convert Facet Body feature
• During Import STL/Scan Data

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
• Fillets, holes, chamfers, etc
• Think 1 Step Ahead
• Use Tool Solids/Subtracts
• Sweep a surface and Trim
• Reference Geometry
• 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

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

• Richer data and smaller file size

▫ Materials and messhes ▫ Supports ▫ ‘Send to Printer’

• Zipped .XML packet. Win10 at the core
• Major machine manufacturers and softwares involved

NX Additive Manufacturing

• Additive Manufacturing Analysis

Tools

• Wall Thickness checks (process

appropriate?)

• Overhang Angle (supports

needed?)

• Printable Volume (will it fit?)

▫ Uses MS 3D Printer drivers ▫ Custom lets you specify build volume

• 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
• 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

NX Additive Manufacturing +Z is build direction

NX Additive Manufacturing SO…

• We can work with STL/Scan Data faster now
• We can modify STL files now

▫ Think Primitive and manage expectations

• Custom Products workflows seem first to benefit

▫ Standard NX Model that is modified by custom STL data ▫ Medical, Footwear, Orthotics

• NX can generate printer-ready 3DP files

Thank You!
