Method for manufacturing a component by fused filament fabrication and apparatus for producing a component

An apparatus for producing a component by fused filament fabrication comprising:

• a substrate plate for depositing layers of the component, the substrate plate having an embedded electromagnet;
• and
• a first printing head for depositing a first layer having magnetic material;
• and
• a second printing head for depositing at least one further layers, wherein the substrate plate is:
• actively magnetizable by passing a current through the electromagnet such that the magnetic material is magnetically attracted by the substrate during production of a component, and
• demagnetizable by switching off the current to the electromagnet such that the magnetic material is not magnetically attracted to the substrate.
