Microlithography is a very widely used technique for the production of micro-scale devices such as very tiny 3D printing in micrometer scale, semiconductor devices, and many other micro-scale products. French microlithography specialistΒ Microlight3DΒ has 3D printed the worldβs smallest version of the Statue of Liberty for the inauguration of US President, Joe Biden.
The 3D printed statue isΒ 1.8mmΒ tall andΒ 0.6mmΒ wide. It is printed with the companyβs latest Long-range Z process and the statue was directly printed on a 1 cent coin which shows that the printing technology is compatible with a variety of printing substrates, notably metallic and opaque substrates. Using this process, higher resolution can be achieved than the traditional red laser systems. The Long-range Z process allows structures for optical micro-parts, meta-materials, and medical devices up to 10mm high using photolithography, up from 0.3mm previously, on a variety of substrates from glass and silicon to metal [1].
βUsers will also be able to make alignments on a pre-existing pattern and print exactly where they want. We had great fun positioning the replica of the statue on the word βLibertyβ on a United States one-cent coin,β saidΒ Philippe Paliard, co-founder of Microlight3D.
He further added:
βResearchers and industrial developers are looking to work on metallic or silicon wafers. Our enhanced 3Dmicroprinting system, compatible with a wide range of materials and substrates, will allow them to micro-fabricate the structures they couldnβt before, to align the laser and print on the tip of optical fibers for micro-optics applications.β
