Yale University in the United States regularly publishes its “Journal of Industrial Ecology” in which the impact of the industry on the ecology is analysed, this year it has been focused on 3D printing.\u00a0In collaboration with researchers from MIT and the University of Nottingham, they delved into existing studies. The\u00a0conclusion about whether it is a sustainable manufacturing method is clear,\u00a0we must moderate the enthusiasm generated by 3D printing with respect to its “spectacular” environmental impact<\/strong>.\u00a0Taking into account all the components of additive manufacturing, from the use of raw materials to waste management.<\/p>\n

Different environmental initiatives have been developed in regard to 3D printing that accelerate the recycling of plastic waste.\u00a0We know some developments such as\u00a0Precious Plastic<\/a>, which develops recycling centers in different countries or\u00a0Plast’if<\/a>\u00a0that seeks to recycle plastic waste from the offices.\u00a0But is this enough?<\/p>\n

Professor Tim Gutowski, who works in mechanical engineering at MIT, explains, however, that the quantitative analysis of the environmental performance of 3D printing is limited.\u00a0Much of this study focuses solely on the energy used during production, rather than the impacts of raw material production, product use or waste management.\u00a0To overcome this lack, Yale University, MIT and the University of Nottingham have carried out more studies.<\/p>

A sustainable manufacturing method?<\/h3>\n

According to Professor Gutowski, there are today two key elements that have given 3D printing this quality of being green technology. Leading to it being considered as a sustainable manufacturing method.\u00a0First, it\u00a0reduces waste.<\/strong>\u00a0Unlike subtractive manufacturing, 3D printing uses only the material it needs when layer by layer is added. Thereby securing that that we have much less waste. In addition, it is capable of\u00a0reusing plastic waste.<\/strong>\u00a0Converting it into printing filaments and creating new products, such as the\u00a0OWA<\/a>\u00a0filament range.<\/p>\n

A more sustainable manufacturing<\/p><\/div>\n<\/div>\n

The second key point concerns the\u00a0accessibility of 3D technologies.<\/strong>\u00a0Manufacturers can now produce directly in the company, which reduces logistics and travel issues.<\/p>\n

Professor Gutowski commented that it is often said too quickly that additive manufacturing is safe for the environment. But several things have to be taken into account.\u00a0First of all, you have to think, in 3D printed media. They are often important: “These supports cannot always be reprocessed back into raw materials.<\/em> It also is important to consider whether the plastics, metals, or mixed materials used in parts made with additive manufacturing can be recycled.<\/em>“<\/p>\n

Yale University suggests that 3D printing on demand and rapid prototyping can\u00a0potentially lead to an increase in the number of disposable consumer products<\/strong>.\u00a0A point that does not necessarily go in the direction of a healthier environmental impact, even if we see that filaments based on hemp<\/a> or biodegradable PLA grow more and more.<\/p>\n

Environment and 3D printing: VOC emissions<\/h3>\n

The researchers also discussed the\u00a0release of volatile organic compounds (VOCs)<\/strong>\u00a0associated with 3D printing that can be dangerous in closed work spaces.\u00a0Although most manufacturers are fighting against this, some machines release toxic nanoparticles;\u00a0however, researchers believe that it is easy to take the necessary precautions.\u00a0There are already some solutions in the market for this, such as the one offered by the Zimple company.<\/p>\n

In conclusion of the research, Professor Gutowski reiterates the innovative capabilities of 3D printing as a sustainable manufacturing method. Reaffirming that it is a method that liberates creativity and offers more performance to the industry.\u00a0However, there are some indirect disadvantages to the environment that are also related to the use of subtractive processes.<\/p>\n

The professor is convinced that\u00a0additive manufacturing is an additional tool to traditional methods<\/strong>\u00a0, not a substitute.\u00a0“While some 3D printing applications may not be\u00a0 environmentally desirable, there are many opportunities for improvement that have not yet been pursued.”<\/p>\n
