In-situ monitoring of additive manufacturing

A system for additive manufacturing of a product from a depositable material, wherein the depositable material is electrically conductive, wherein the system comprises

• a support element,
• a material addition system, and
• at least two electrodes;
• wherein the system comprises a fused deposition modeling system,
• wherein the material addition system is configured to melt the depositable material being deposited;
• wherein
• the support element is configured for supporting the product;
• the at least two electrodes comprise one or more first electrodes configured at a surface of the support element;
• the material addition system is configured for depositing the depositable material at one or more of (i) the support element and (ii) deposited material, thereby forming the product;
• wherein the material addition system comprises a nozzle for layer-wise depositing of the depositable material at the one or more of the support element and the deposited material;
• and
• any one of the electrodes is configured for (i) electrically contacting the depositable material being deposited or (ii) electrically contacting the deposited material, during depositing the depositable material, wherein (i) the depositable material being deposited in combination with at least a portion of the deposited material arranged between the electrode and another one of the electrodes define an electrically conductive path or (ii) at least a portion of the deposited material arranged between the electrode and another one of the electrodes define the electrically conductive path.
