3D Printing: Wiki View

3D printing (or additive manufacturing, AM) is any of various processes used to make a three- dimensional object. In 3D printing, additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3D model or

• ther electronic data source.

FACT

Key Additive Manufacturing Benefits

• Faster time to market for product

introductions and revisions

• End-to-end design cycle cost savings

– Concept phase: Inexpensive concept modeling – Design phase: Design verification & 3D fitment check – Build/Test phase: Prototyping materials that mimic production parts –

• Mfg. phase: Elimination of part/job specific

tooling and their own development cycles

Key Additive Manufacturing Benefits

• New design freedoms vis-à-vis elimination
• f many manufacturing limitations

– Parts that can only be built via AM techniques

• Improved product performance & quality,

affordable continuous improvement

• Quick design cycles = more ideas = more

breakthroughs = improved designs

• Improved communication = improved

decision making & efficiency

Basic Truths About Additive Manufacturing

• There is no single 3D Printing

technology that does everything best

• Each technology has strengths and

weaknesses, e.g. material properties, speed, equipment cost, post-processing

• 3D printer choice should primarily be

driven by intended APPLICATIONS

Basic Truths About Additive Manufacturing

• Many companies rely on multiple 3D printer platforms for different

applications or they will outsource for applications that their printer fails to satisfy

12 Early Melni Connector Concept

• A great 3D printer is not a cure for poor

CAD design practices

– CAD training, architecture, review, validation,

• etc. are important for successful AM

metal powder to the desired layer thickness/ density on return.

• Parts from one batch to the next are sintered with consistency and quality
• Easier to handle size inconsistency in the metal powder and still achieve better results
• Helps to work with smaller metal powder grain size ( down to 3 micron) when extreme
• detail is needed
• Works successfully with spherical and non-spherical powder particles
• Works with Metal and ceramics in the same equipment
