EOS, a manufacturer of laser-sintering equipment, has launched the EOS Quality Standard, an initiative of the EOS e-manufacturing partner programme that is open to all customers.

The purpose of this programme is to define a package of requirements that guarantees the high quality of e-manufacturing parts and services.

The procedures for this standard are to be integrated into customers’ ISO: 9001 quality management systems.

Eli Liechty, leader of operations/manufacturing RMM at Morris Technologies, which has implemented the new initiative, said: ‘[The EOS Quality Standard] highlights the importance of controlling the entire additive manufacturing supply chain, ranging from system maintenance to operator training, material qualification and critical system parameters.

‘This standard will supplement our international ISO: 9001 and industry-specific AS9100 and ISO: 13485 quality systems,’ he added.

The e-manufacturing provider must have implemented a quality management system (QMS) with a valid certification according to ISO 9001 and must define and implement quality assurance procedures for the production and supply of laser-sintered parts within that QMS.

There are five types of qualifications that a customer has to integrate into the QMS.

Personnel qualification is one factor; for example, the e-manufacturing provider’s staff members are expected to have the knowledge and skills for the relevant technology.

The provider also must assure machine status according to quality procedures.

This status is to be specified and documented, regular maintenance has to be carried out and the environmental conditions that the machine is operating in must conform to the defined EOS Installation Requirements.

Second, if the customer uses a material that has been released by EOS for the relevant technology, EOS provides them with the appropriate set of procedures to meet the criteria of the standard.

In this case, the third criterion – using the right parameter sets – is met by deploying the system-specific EOS parameter set and powder material.

The fourth element of the quality standard ensures the conformity of part design with the relevant design rules.

Finally, certain demands have to be met concerning data preparation and post processing.

These should be in accordance with recommendations published by EOS for the relevant machine and powder material.

Otherwise, the customer needs to specify what procedure has been used and why or how that procedure has been qualified.

With this quality standard, and its recently presented Part Property Profiles, EOS continues expanding the use of its e-manufacturing technologies in production.

The provider of any parts or services supplied with reference to this quality standard is solely responsible for the fulfilment of the requirements and for any information provided in relation to those parts or services.

Peter Klink, executive vice-president of sales and support, said: ‘Customers of an entity that follows the EOS Quality Standard can expect consistent part quality from their e-manufacturing provider.

‘The standard allows them to distinguish between providers by a reference to an independent standard,’ he added.
