Nature uses precisely designed structures to create shapes that fit the needs of

strength, flexibility and rigidness while still keeping them light in weight. The

creations of similar structures are very difficult and often not possible to achieve

via traditional manufacturing technologies. One of the key advantages of additive

manufacturing is the flexibility to create shapes which are impossible or too costlyto produce with the traditional technologies. Optimizing your designs (creation

lattice structures) and translating them into lightweight components is therefore

regarded as one of the most promising potentials of the Additive Manufacturing

(AM) industry.

The Key Benefits of using the 3-matic Lightweights Structures

Module:

The Lightweight structures module offers a unique combination of a tool setequipped with:

o creating uniform and random internal structures,

o creating structures following the contour of external surfaces

o While also giving freedom to connect internal structures with differentexternal surfaces.

3-matic allows you the flexibility to use structures from its internal library.You can grow your library based on your own design needs by designing

structures in CAD packages and easily importing in 3-matic.

3-matic uses highly innovative internal technology and links to Materialises

data preparation software to directly export sliced files for printing. This

7/26/2019 3 matic

powerful combination means that the limitations and issues related tocomputation of complex structures are completely bypassed.

3-matic CAD Import Module:

With the CAD Import module, you can create STL data from Iges, VDA, Vrml,

Catia V4 and V5, UG, Pro-E and Step files. 3-matics interactive CAD importreads the surface structure of your CAD file and lets you create detailed surfaces

by taking low-accuracy surfaces and reloading them with a higher resolution.

3-matic CAD Link Module:

The CAD Link module gives you the possibility to easily bring your file back to

CAD. As a combination of the segmentation tools and intelligent automatic

splitting, this module offers you the complete solution to convert STL files to Igesor STEP. Included in the conversion is a feature recognition where, for example,planes will be recognized as planes.

3-matic - Remesh case study:

For case study of Westland Helicopter, 3-matic software is used generating

surface meshes for their CFD projects. WHL (Westland Helicopters Limited)

wished to expand the range aerodynamic data available for this helicopter beyondthat accessible from wind tunnel testing. This required the generation of a new

CFD model of the helicopter. During the project, Westlands Fluid Dynamicsand

Environmental team faced several challenges, which they discovered could be

tackled easily using 3-matic.

3-matic-Remesh reduces time needed to generate watertight

surface meshes:

Lacking a 3D computer model of the helicopter, a subcontractor scanned the

surface of a wind tunnel model. Reverse engineering the scanned data resulted in a

fi le that contained too many surfaces (534MB STEP fi le) to read into their

surface-meshing tool, Gambit 2 , on the fi rst try. The data could be processed after

the number of surfaces was reduced manually. Unfortunately, two complex but

significant details, the FLIR and winch, were omitted completely, because these

objects were poorly scanned and the subcontractor couldnt repair the data. In

addition, the supplied surfaces didnt join toform a consistent shell. At least one of

the surfaces supplied was physically impossible to create a real solid. It wasnt

feasible to proceed with this project without a significant effort to repair the bad

geometry. However, the missing components would still be missing. At this stage

Materialize flew to Westlands aid, providing them in a few dayswith a high

quality surface mesh that comprised all components.

Fast preparation and repair of the defective scanned data:

The omitted elements were essential in this project. Thats why the fi rst thing the

3-matic team did was to repair the defective data. This process involved

segmentation of the FLIR and bracket and repair work to the surface mesh, like theremoval of all overlapping and intersecting triangles. Next, our 3-matic engineer

gave the winch body model the same treatment.

The scanning process didnt capture all features completely. The winch brackets

connecting the winch to the helicopter bodyfor example could only be scanned

partly (see Fig. A)However, these brackets were easily reconstructed in 3-matic

by sketching and creating a cylinder on the scanned data.

Fig. b

Rapid import and repair of the reverse engineered data:Materialize staff also generated the surface meshes for the bad geometry in the

reverse engineered surfaces supplied by the subcontractor. See figure 2.a & b for

an example. All this repair work took about 17 hours. Had the original scanned

data instead of the often imperfectly reverse engineered surfacesbeen available,

the 3-matic team estimates that they would have been able to create a quality

surface mesh in less than a third of that time.

3-matic-Remesh reduces time needed to generate watertight

surface meshes:

The degree of skew in the resulting high quality triangle surface mesh conformed

to the conditions imposed by CFD software, in this case Gambit or T grid from

Fluent. The optimized mesh was then grouped into faces for export to the fluent fi

le format (see Fig.3). With a single mouse click we created a box around the

model, which is a highly labor-intensive task in CFD pre-processing software. The

box enabled the creation of volume meshes representing the air around the

helicopter, necessary to analyses the air flows. It took us only ten hours to transfer

the 3D model into a mesh ready for flow analysis.

Good CFD results of optimized model:

Further, Westland could turn these faces into volume meshes using TGRID. Later,

they solved and post-processed the volume meshes using FLUENT software.

Designer said The CFD results of the model supplied by Materialize were verygood; for example, the drag of the aircraft at the design point was overestimated by

less than 4% compared with the wind tunnel tests.
