3D printed Murano glass exhibited at Glass Week »3dpbm
Although absolutely breathtaking, world famous Murano glass cannot be easily recycled with normal glass due to the chemical elements used to color it. Consequently, Murano glass waste must be treated as “special waste”, which constitutes an important economic and environmental stake for the activities of the island of Murano. The VERO2 project led by designer Matteo Silverio used 3D printed Murano glass to explore a possible solution.
During Venice Glass Week 2021, in Maison203 boutique, Silverio will present the first collection made by merging waste glass from Murano and digital technologies. These, along with extensive material development support, were provided by Italian 3D printer manufacturer WASP, and in particular, Nicola Schiavarelli, who follows special projects at the Massa Lombarda-based company.
The VERO2 project aims to develop a new way of producing Murano glass objects by locally reusing the waste from foundries and artisanal glass factories. As a technical partner of VERO2, WASP has made its technologies available to accelerate a “blue conversion” of the glass island, promoting circular economy processes using waste to create new objects. To do this, WASP has shared its know-how in the treatment of fluid-dense materials in order to make the 3D printing process more reliable.
The specially developed workflow for 3D printed Murano glass turned waste glass into something new. A modified Delta WASP Clay printer was used to extrude a compound mainly composed of Murano glass powder. The ink is 97% Murano glass powder which is used to create a paste that can be extruded and deposited using WASP’s proprietary LMD (Liquid Modeling Deposition) technology. The object is then sintered in an oven at 700 ° C, so that the non-vitreous materials are burnt away from the initial compound.
The glass sintering process can present a challenge, but the end result was a 100% Murano glass object. Hence the name VERO2, where the word “Vero” means “Real” in Italian and also Glass in the Venetian dialect.
