A brand new free-to-download white paper from the World Financial Discussion board (WEF) predicts widespread, mass manufacturing of 3D printed industrial components within the subsequent decade and highlights the connection between the coronavirus pandemic and the heightened use of additive manufacturing (AM) applied sciences. Concentrating on senior business executives in manufacturing firms, the analysis titled “An Additive Manufacturing Breakthrough: A How-to Information for Scaling and Overcoming Key Challenges” gives a sensible understanding of what AM can ship right this moment and why some are reaching that potential whereas others should not.
Developed in collaboration with ETH Zurich and three Fraunhofer analysis institutes (IGCV, IPT, and IAPT), this white paper highlights 4 greatest practices and three real-world case research to point out paths for overcoming the principal present challenges of AM. Charting the course for “the true story of AM” meant the WEF reached out to manufacturing leaders throughout completely different industries to outline what it describes as a brand new “return on funding (ROI)-based narrative of the industrialization of AM.” Interviewees included AM specialists in famend firms like Stratasys, Nano Dimension, Spectroplast, HP, Carbon3D, and EOS.

WEF means that the very best practices for the adoption of AM are:
Implement in iterations
Firms are suggested to start out the AM adoption course of with functions of minimal complexity. As soon as accomplished, they will transfer to extra superior functions, steadily rising their AM competence and degree of adoption.
Pull, don’t push
The WEF recommends that to extend the chance of profitable implementation; firms ought to construct AM functions round its want. This market-pull technique contrasts a technology-push strategy, the place organizations try and showcase AM’s technological capabilities in overly advanced demonstrators whereas serving no or solely restricted enterprise worth. “The large hurdle in AM expertise is not the technical feasibility however the cost-benefit ratio and discovering an appropriate enterprise mannequin,” states the white paper.
Collaborate to enhance
One of many greatest AM adoption accelerators is collaborations that may assist an organization fill competence gaps or lack of skilled expertise and data. Actually, all through the paper, the WEF highlights that partnerships must be strengthened to scale back prices alongside all the course of chain. Actually, one of many goals of the paper is to assist senior business executives incubate new collaborations and partnerships by mobilizing the worldwide manufacturing group.
Strategize and assist
The WEF encourages companies to create an AM technique early on and align particular implementation initiatives with this roadmap whereas supporting the implementation to succeed.
To get to that time, although, the paper’s authors seemed into three particular instances that reveal how AM challenges may be overcome. The examples chosen reveal that present key alternative drivers may be discovered inside the digital course of chain, in new AM supplies, in licensed provide chains, and the appliance of novel enterprise fashions. To indicate how the digital thread may be leveraged to enhance AM functions, WEF selected an automatic design platform for 3D printed orthoses developed by 3D printing software program developer Trinckle and healthcare firm Aqtor!

One other nice instance showcased within the paper is a novel materials developed by Johnson & Johnson for extremely modern functions. The bioresorbable materials mix primarily based on polycaprolactone (PCL) creates patient-specific implants via selective laser sintering (SLS). With greater than 90 implants efficiently put in, this case examine underlines the potential of novel AM supplies and the way they will present vastly superior AM functions with elevated performance and higher availability at a aggressive price.
Lastly, the WEF paper factors out a case examine between Central Europe’s largest railway firm Deutsche Bahn (DB), and worldwide service company TÜV SÜD. The duo teamed as much as develop a certification scheme for suppliers of AM spare components and end-use elements to take care of passenger and cargo autos, guaranteeing the fixed availability of spare components. So far, greater than 25,000 spare components and end-use steel and plastic elements have been manufactured at DB.

Aiming to assist firms overcome any roadblocks alongside the AM worth chain, the case research and pointers supplied by the authors of the paper reveal that present key alternative drivers may be discovered inside the digital course of chain, in new AM supplies, in licensed provide chains, and the appliance of novel enterprise fashions.
Moreover, the long run industrialization of AM is mentioned in relation to potential manufacturing eventualities, key enablers, and options. An total evaluation demonstrates {that a} joint step in the direction of the industrialization of the AM course of chain is required to foster sustained and sustainable progress of the business. The report additionally spotlights seven overarching themes in a name to motion, addressing detailed statements for stakeholders within the AM ecosystem to facilitate this course of.
Whereas the paper is upbeat about what firms can do to extend AM adoption, specialists level out that right this moment and within the foreseeable future, the manufacturing prices of AM components are a principal impediment.
“This not solely refers to machine and materials prices however that perceived lack of robustness and high quality even have a major influence on prices. Each components result in excessive quality-assurance prices after the AM course of. Advanced geometries of AM components, small lot sizes, and different particularities of AM make it difficult to post-process and automate the manufacturing. Consequently, post-processing accounts for a major share of the general half prices,” states the doc.
Speaking to so many business specialists to create a doc like that is essential as a consequence of its content material and since the WEF is without doubt one of the most revered impartial worldwide organizations with worldwide attain. Ever since AM was highlighted as one of many WEF’s 10 rising applied sciences by the group’s Meta-Council on Rising Applied sciences in 2015, it has been on the forefront of its agenda and different disrupting superior manufacturing processes. This white paper is a superb new place to begin for the subsequent era of AM applied sciences in a worldwide context altered by the Covid-19 pandemic. This new regular, the place the way forward for manufacturing is shifting away from conventional processes, has rendered AM a novel technique that can assist create extra resilient and versatile provide chains.
