New Liquid for Fused Deposition Modeling 3D printing method/ Source: MDPI
The Polish company Sygnis, which specialises in high-tech equipment, has reached an agreement with Adam Mickiewicz University to exploit the university’s exclusive technique of filament modification for fused deposition modelling.
Using a standard FDM 3D printer and polymer material, the Liquid for Fused Deposition Modelling (LFDM) technique enables the direct incorporation of a wide range of chemical substances during the process of 3D printing. These chemical substances include chemicals, antibiotics, dyes, pesticides, trace elements, radioactive materials, nanoparticles, proteins, fertilisers, peptides, phosphors, monomers for polymerization, and active ingredients.
Thanks to the LFDM technology, chemical compounds that were previously unable to be utilised because they underwent chemical or physical transformations during traditional processing can potentially be incorporated into polymer filaments for fused deposition modelling. This was previously thought to be physically or chemically impossible. Because it does not need expensive and energy-intensive processing equipment in the laboratory, LFDM may also be used by those who do not have access to specialist equipment of fused deposition modelling. This is due to the fact that it removes the requirement for such equipment.
Combining chemistry with 3D printing for fused deposition modelling
The licence granted under this agreement is the central point of reference for all activities related to the production, promotion, sale, and distribution of items made using the aforementioned procedure of fused deposition modelling. This licence is valid in Poland until June 27, 2033, and is paid for by royalties on the profits made from the sale of items that employ the patented process.
The company anticipates a rise in sales of 3D printing accessories and peripherals over the course of the 10-year term covered by the licence, as well as an improvement in its standing in the processing and chemical industries. In the event that the company and Adam Mickiewicz University in Pozna are able to collaborate on the process of commercialising the strategy of fused deposition modelling, the company will increase its relationships to academic institutions.
The notion is novel and very basic, and it aims to combine chemistry with 3D printing. About three years ago, our group conceptualised and developed the plan. Prof. Robert E. Przekop from Adam Mickiewicz University in Pozna says, “After preparing the patent application, we have published our solution and encourage you to use the LFDM method and its further creative development.” Przekop is speaking on behalf of the university.
Thinking back on Sygnis’s 3D printing experience
After the invasion of Poland by the Russian military, 3YOURMIND, Sygnis, and TeenCrunch came together to launch the ‘Tech Against Tanks’ campaign. The project’s goal was to connect 3D printing hubs and manufacturers in Poland, Germany, and the Ukraine in order to streamline the manufacturing and delivery of 3D printed medical, tactical, and protective equipment. More than a dozen machines and 3D printing materials were made available in Lviv, Ukraine, thanks to Sygnis’s participation in the effort.
Sygnis was able to effectively replicate two historical items by employing techniques associated with 3D modelling. Following a delay of almost to three centuries, the first flawless replicas of the Order of John III Sobieski and the Order of the Immaculate Conception of the Holy Virgin Mary have finally been produced. Sygnis was able to print three-dimensional objects with a degree of accuracy in the micron range by utilising a technology known as Digital Light Processing (DLP). After being meticulously hand-painted and cast in brass, the Orders were eventually handed to the Foundation of the Order of John III Sobieski.
