Injection Moulding Asia 3D Printing
A technology to revolutionise manufacturing 3D printing growth According to Wohlers Associates, an independent consulting firm that has been a fervent tracker of the trends in AM and 3D printing, the market for 3D printing products and services grew to US$3 billion in 2013 attaining a CAGR of 34.9%, the highest in 17 years. Wohlers also adds that the growth of worldwide revenues over the past 26 years has averaged 27%, with the CAGR for the past three years (2011-2013) reaching 32.3%. It also expects worldwide revenues to reach US$12.8 billion by 2018 and to exceed US$21 billion by 2020, as stated in its Wohlers Report 2014. Wohlers also believes the industry will continue strong growth over the next several years, fuelled by sales of under US$5,000 “personal” 3D printers, as well as the expanded use of the technology for the production of parts, especially metal, that go into final products. “The industry is experiencing change that we have not seen in 20+ years of tracking it,” stated Tim Caffrey, Senior Consultant at the company and author of the report. He added, “What’s most exciting is that we have barely scratched the surface of what’s possible.” Caffrey also pointed out that the revenues are in “manufacturing, not prototyping.” This is reaffirmed by Anthony Vicari, Lux Research Associate and lead author of a report titled How 3D Printing Adds Up: Emerging Materials, Processes, Applications, and Business Models. “Consumer uses of 3D printing attract most of the headlines, but industrial uses, from moulds and tooling to actual production parts, are quietly having the greatest pace,” said Vicari. He adds that the field is “still just getting started,” stating, “Advances in processing and printable materials technology are still necessary for future growth.”
The 3D printing process is only just beginning to realise its potential. From relatively simple prototypes to complex made-to-order products for the aerospace, defence, medical and industrial sectors, 3D printing technologies are expected to redefine the processing sector.
T
hough it has been around for a while, 3D printing or additive manufacturing (AM) was thrust into the limelight when German machinery maker Arburg premiered its new machine concept last year at the K2013. The Freeformer, as it is known, is said to costefficiently produce plastic components as one-off parts or in small batches directly from CAD data and without a mould. The firm says that inexpensive standard granulates can be processed by first being melted in a plasticising cylinder, similarly to the process for injection moulding. A stationary discharge unit with a special nozzle applies the plastic drops Arburg’s Freeformer is a new system for additive to the movable manufacturing of plastic parts component carrier in layers, using high-frequency piezo technology. It enables the production of fully-functional parts and not just models and prototypes. The excitement surrounding the launch of the Freeformer was enthralling simply because the process has never been given much publicity before or perhaps because the industry is at a spurt growth stage.
Overcoming impediments to growth According to Lux’s report, the 3D printing market will be driven by the aerospace, medical, automotive, consumer products, architecture and electronics sectors. It expects the sector to nearly quadruple to US$12 billion in 2025. Printers alone will be worth US$3.2 billion, with US$2 billion for formulated materials and US$7 billion for the value of parts produced. Currently, four printer companies, 3D Systems, Stratasys, EOS and Arcam, dominate the market and hold a combined 31% printer market share, according to Lux. Lux also notes that the “razor/blade model is a hurdle,” with 3D printer companies often selling 5
