Laser assemblers offer a new processing technique to fabricate complex 3D‐microstructures. Based on Holographic Optical Tweezers (HOT) spherical microparticles can be manipulated with highest flexibility and precision. Using a Spatial Light Modulator (SLM) the incident laser beam is rearranged into flexible light patterns in order to generate multiple spots which can be modified with a frame rate of several tens of Hertz. Additionally, non‐spherical particles manufactured e.g. by a 2‐photon‐polymerization (2PP) process can be utilized to realize more complex building blocks. A combination of contactless manufacturing by 2PP and manipulation by HOT provides the possibility of analyzing generated 2PP‐structures on its manipulative performances as well as the assembling of the 2PP‐preforms.
