Method for producing electronic components by means of 3D printing

A method for producing an electrical component via a 3D printing, the method comprising:

• preparing a first layer comprising a valve metal powder;
• consolidating at least a portion of the valve metal powder of the first layer via a first selective irradiation with a laser;
• applying a second layer comprising the valve metal powder to the first layer;
• consolidating at least a portion of the valve metal powder of the second layer via a second selective irradiation with the laser so as to form a composite of the first layer and of the second layer;
• applying respective additional layers comprising the valve metal powder to the composite;
• and
• consolidating at least a portion of the valve metal powder of the respective additional layers via a respective additional selective irradiation with the laser,
• to thereby obtain the electrical component,
• wherein,
• the valve metal powder is selected from aluminum, bismuth, hafnium, niobium, antimony, tantalum, tungsten, molybdenum and zirconium, and mixtures and alloys thereof, and
• the valve metal powder comprises a BET surface area of 0.001 to 10 m2/g.
