EOS 2010 � EOS tooling applications� Augustin Niavas

What is DMLS for tooling?


Definitions: e-Manufacturing, DMLS

— e-Manufacturing is the fast, flexible and cost-effective production directly from electronic data.

— EOSINT M systems builds up, additively layer by layer, metal parts, directly from metal powder, using a focussed laser beam, which fuses metal powder into solid part by melting it locally: this is DMLS.

— One in particularly most interesting and important field of application is the design for tooling inserts.

Source: EOS


DMLS with Direct Tool push on tooling design

— One of the greatest advantages of DMLS is the „design driven approach“

— DMLS makes possible the implementation of tools with complex geometry and the realization of heating/cooling channels, designed to follow the moulding surfaces of the tool: this process is known as conformal cooling.

— Through an optimised positioning of the tempering/cooling system, it’s possible to achieve a lower or uniform temperature in the mould and a performing tempering of the tool inserts

Today Direct Tool means advanced tooling

What means conformal cooling?

Source: EOS

— Design driven manufacturing or freedom of design

— Optimised cooling/heating channels for productivity and quality improvement

— Reach hot spots and critical areas of the insert

— High number of possible designs: knowhow dependant suitable to thermodynamics rules and complexity is not a cost-driver

— Possible validation with simulation

— Uniformity of cooling and improvement of the insert life time

Leave under defined circumstances the area of convential tooling and choose a new way for solving challenges

The business development growths along 3 axis

— DMLS as reference technology: the use of the technology and the possibilities it offers has to be diffused (reach the decision makers, industrial associations, etc…)

— Cooperations to speed up improvement: all over the manufacturing chain, from advanced tooling trainings suppliers to toolmakers, from software companies to research institute

— EOSINT M systems as serial production machine for tooling: gather the customers and market feedback, works together with product management to explore completely the potential of the machine

DMLS advantages for injection moulding


DMLS has a positive impact on the injection moulding manufacturing chain

— The example concerns a thin-walled throw-away product (cheap raw material)

— DMLS has a selective effect on the costs along the manufacturing chain

— Advantages for inserts costs, productivity, cycle time, product quality and material usage

— Effects are additionally positive

Hints to advanced tooling design


Design recommendations (1)

If you need to split your channels, then take care

of balancing them.

Cool down critical area, reaching them with free form

shape

Follow the contour of your insert and keep distance to

surface/wall constant

Give preferences to smooth lines, avoid

right corners

Do not hesitate to “boost”your cooling system if

necessary

Criteria of choice for inserts for successful testing of technology


The roadmap to the successful process

— Identify the most suitable geometry (core or cavity)

• Dimensional criteria

• Complexity criteria

• Challenging injection process

• Free form shape

— DMLS oriented design from the beginning (if possible)

— Cooperate with us and our service provider to optimise or the create the design (best case)

— Follow the basic design rules

— Send us the 3D Data (under NDA if necessary)

— EOS builds the inserts, you test it


3 types of criteria should guide us to a suitable case study

— Principal criteria

• Geometrical: parts/insert should fit into the building envelope (with or without hybrid)

• Material requirements: Maraging steel material of choice

• Case study free of NDA

— Application criteria

• Industry sector: packaging, medical, electrical and domestical appliances

• Complexity of heating/cooling system

• Innovation Potential

— Plastic product criteria

• Cycle time reduction potential

• High scrape rate
