• Wind Tunnel Testing

Testing Applications

29

Form Testing

• Visual Appreciation

• (Concept Modeling)

• Most common Application in 3D-P

• (Also the easiest)

• Why Stratasys:

• “Printing Reality”

• Accurate representation of product

30

Fit & Assembly Testing

• Fitting elements together

• Testing components fitting

• Not a trivial Application

• Why Stratasys:

• Accurate, Good Tolerance

• Fine Details

• Material Variety (Transparent)

• Thermoplastic Stability

31

Functional Testing

• Validate functionality of designs

• Test a product in its environment

• Identify potential flaws

• Why Stratasys:

• Good mechanical properties

• Large variety of materials matching end-use requirements

• Accurate, stable materials

32

Functional Testing

33

Ergonomic Testing

• Ergonomics: designing equipment to fit the worker

• No CAD SW offers proper ergonomic grasping

• Prototyping is critical in this phase

• Also important in manufacturing tools

• Why Stratasys:

• Large variety of materials

• Smooth parts

• Rubber-like (gripping)

• Sparse internal fill

Tooling Applications

37

Silicone Molding

• Also known as:

RTV Molding, Vacuum Casting, Urethane Casting, Soft Tooling

• Used for short series production

• Stratasys part is used as a master pattern

• Why PolyJet:

• Smooth surface (critical)

• Fine details

• Good HDT for silicone molding

PolyJet ***

FDM **

38

Injection Molding

• Using the 3D Printed mold to inject plastic

• Done using Digital ABS material (Connex)

• Enables fast and inexpensive spec material prototyping

and short series production

• Consult HQ applications team for further details and

support

PolyJet ***

FDM *

39

Rapid Tooling

• Create a mold used for tooling

• Print the tool, not the part

• By creating the negative of your design

• Typically, material injected is Silicone or Wax

• Why PolyJet:

• Fine details

• Smooth Surfacing (Glossy best)

• Good HDT for silicone

PolyJet ***

FDM ***

40

Sand Casting

• Using the PolyJet model as a master

to generate sand mold

• The sand mold is then held in place

using chemical binder or pressure

• Metal is then cast into the sand mold

• Also a good fit for creating Sand Core Boxes

• Best fit for small- medium size parts with high details

FDM ***

41

Blow Molding

• Manufacturing process using air to inflate

plastic inside a mold cavity

• Stratasys technology can be used to create

molds for blow molding processes

• Best suited for pre-production, prototype tooling

• Create entire mold or mold insert

• Can be used in Injection blow molding and

Extrusion blow molding processes

• Living Hinges

• Gaskets Plugs & Seals

• Shock Absorption

• Impact Resistance

• Over Molding

• Digital ABS Functional Testing

• Soft Touch Parts

• Labeling & Texturing

Connex Applications

43

Over Molding

• Process of 2 materials combined, producing a single part

• Typically a rigid plastic with a rubber-like

• Traditional method required silicone molding & gluing

• Why Objet:

• We are the only ones that can print multiple materials

• Connex rigid & rubber-like combination - perfect for over molding

44

Digital ABS

Functional Testing

• Digital ABS material allows for simulation of ABS

• Only on Connex (Digital Material)

• Material allows for further Functional Testing

• Why is this important:

• Customer wans to fully evaluate the prototype

• Have better understanding of end-product

• The more they can do with the model, the better!

45

Soft Touch Parts

• The ability to generate soft touch parts

• Idea is less for functional testing

• Simulating rubber-like parts

• DM selection allow pinpointing Shore desired

• Typically used for visual appreciation

46

Labeling & Texturing

• Ability to label and create texture on a given Connex parts

• Advantage in Concept Modeling (Form Testing)

• Advantage in Design Validation (Qualification / Categorization)

• You can label and monitor different versions in print

• Texturing is more important than people initially think…

47

Living Hinges

• Thin flexible hinge joining two rigid parts together

• (Allowing bending along the line of the hinge)

• DM excellent elongation-to-break & tear resistance

• Allows for living hinges to be generated on Connex

• Living hinges can be used for:

• Caps and packaging

• Clips

• Left and right clamp shells

48

Gaskets, Plugs &

Seals

• You can use DMs to determine seals material

• Critical in product design

• With Objet you can just select the part…

• And print that area in a certain DM desired

• Remember: Our materials are air/water tight

• Top is a prototype printed by Objet (lid)

• Bottom is the final product…amazing no?!

49

Impact Resistance

• Parts can be coated using a DM to generate impact resistance:

• Simulates behavior of part on strong impact

• (i.e. drop tests are used to determine impact resistance)

• Various coating determinations different resistance levels
