Grundlagen AM an der TU München

Additive fabrication of end products. In direct manufacturing the part has all the characteristics of the end product or is accepted by the customer as suitable for series production. Post-processing treatments, e.g. to produce functional surfaces, for heat treatment, etc. may be required before delivery to the customer. If tools/molds (negatives) are generated through AM for the subsequent processing of functional/ markedready products, it is called Direct Tooling.

• Reduce time to market by accelerating prototyping
• Reduce the cost involved in product development
• Making companies more efficient competitive at innovation

• Reduce labor costs
• Avoid costly warehousing
• Enables mass customization at low costs

• Material type (ceramic, plastics..)
• Machine architecture 
• Material state(liquid, powder, ..)
• Energy input strategy

9. Use

• Parts are directly available
• With complete capacity utilization full profit can be realized
• Competitive advantages due to AM know how

• All processes are available --> Optimal process for product
• Due to rapid innovation of AM we always have the newest technology available
• Pre defined prices for better calculation

Model:

• Depiction (darstellung) of a system with not so much details

Prototype:

• Level of details is nearly identical to the final product

Additive fabrication of parts limited functionality, but well defined specific characteristics.

The material can be engineering material adn the design can be suitable for series production.

--> It gives us more knowledge of the product earlier in the process!
