Materials Solutions, a Siemens business, has received accreditation from the National Aerospace and Defense Contractors Accreditation Program (NADCAP) for additive manufacturing in the aerospace sector. A reported first for a UK 3D printing company in this industry Phil Hatherley, General Manager at Materials Solutions, comments, “We knew that in order to deliver the highest quality parts for the aerospace sector we needed to get the NADCAP accreditation to show we were serious about working in the sector.”
NADCAP and the aerospace sector
NADCAP is a cooperative, industry-managed approach assessing the conformity of ‘special processes’ set by technical experts, suppliers, the National Physical Laboratory, and the National Measurement Institute.
It is universally recognized and incorporated by the aerospace industry for risk mitigation activity as it validates compliance with industry standards, best practices, and customer requirements. Both Italian metal 3D printing service provider Beam IT and QC Laboratories, Inc., a non-destructive testing (NDT) services company, have NADCAP approval for aerospace production.
CECIMO, the association representing the interests of machine tool and manufacturing technologies, has released a new statement concerning additive manufacturing’s position in upcoming discussions by the European Commission.
Having given a formal statement in March 2019, CECIMO has reiterated its commitment to keeping additive manufacturing at the center of decisions relating to product liability, intellectual property (IP) rights, and the U.S.-EU trade deal.
“Before the end of the year,” the association states, “additive manufacturing will be at the centerstage at the European level.”
The Commission is due to publish a new study and guidelines that will rekindle debates surrounding quality standards and the difference between Business to Business (B2B) and Business to Consumer (B2C) relations. In such debates, the association reiterates, “CECIMO will address policymakers to avoid burdening the sector with unnecessary regulation.”
3D printing was pioneered way back in 1986 but has recently begun to enter the public consciousness. Over the past ten years, it has blurred the boundaries between science fiction and fact. It is also known as Additive Manufacturing and is used in the automobile industry, aerospace & defence, retail and in the medical healthcare industry, amongst many others. A major component of this is the 3D printed drugs market. 3D printing helps make what was once expensive and inaccessible much more cost-effective. Can this be more apt and necessary anywhere else than in the field of medicine? 3D printing is already used to print artificial bones, to create surgical materials with 3D scans to replace a damaged or missing bone and even to create hearing aid devices. Skull implants have been made for people with head injuries and even titanium heels to replace bone cancer afflicted patients.
There are several factors which help the 3D printed drugs market to grow. One key advantage is their instantaneous solubility. 3D printed drugs are produced using powder bed inkjet printing. The elements of the drug are added in a layer by layer approach akin to 3D printing for any other device. This makes the drugs easier to swallow and can be very helpful for patients suffering from dysphagia. 3D printing could also augment the arrival of individualised drugs, or the creation of a combination of drugs. They could be customised for each patient, which would help much more than batch-produced drugs since they would be created specifically taking into account that patient’s medical history. The 3D printed drug market could also make children far less resistant to taking their required medication, since they may be able to choose the shape, colour, design and even taste of the tablet! These are anticipated to be the main drivers of the 3D printed drug market.
Everyday products that fill a household seem simple enough to make. However, most require a complex mold process. First, a liquid is poured into a mold cavity. After it dries, the mold is peeled away to reveal the new plastic design.
Items like plastic bottles, soap dispensers and medicine bottles are all made with this process. Most cosmetics also come in plastic containers made with mold releases.
The rise of 3D printing has made it easier than ever to design complex shapes without the need for a mold. The technology is making a significant impact on several industries, including the cosmetics industry.
Global standards developer ASTM International has announced the second round of funding to support the research and development of standards for the additive manufacturing industry.
Comprising an investment of $300,000 and in-kind contributions, the funding will aid ASTM International Additive Manufacturing Center of Excellence (AM CoE)’s objective to address the needs for technical standardization in the growing additive manufacturing industry.
The investment covers nine research projects helping to expedite standards in additive manufacturing. Dr. Mohsen Seifi, ASTM International’s Director of Global Additive Manufacturing Programs, explains that each project contributes towards different standard gaps in design, feedstock, process, post-processing, testing, and qualification. Seifi adds,
“WE ARE THRILLED TO FUND SOME OF THE MOST CRUCIAL AND HIGH-IMPACT RESEARCH PROJECTS IN ADDITIVE MANUFACTURING TO ACCELERATE STANDARDIZATION.”
The fifth Innovation Food Conference — iFood 2019 — will be held at Anuga in Cologne, Germany, in October. Suitable for food retailers, technologists and manufacturers, the conference aims to jointly work out approaches for the development of efficient value chains for sustainable and attractive products.
Speakers at the iFood conference will discuss the ecological, social and economic dimensions of sustainability, addressing issues such as ethics, animal welfare, resource efficiency, consumer health and food authenticity.
Presentations about digitalisation will encompass many topics pertaining to the food industry. The conference will question what digitalisation offers to the food industry in terms of transparency and traceability, and the role of artificial intelligence within the food industry. Experts will provide insights into the economic impacts and opportunities of digitalisation, alongside discussing topics such as blockchain.
3D printing is hitting the runway at New York Fashion Week as textiles are using the technology for designs.
Stratasys, threeASFOUR and Travis Fitch collaborated on the Chro-Morpho collection, which is inspired by microscopic colors and light filtering of butterfly wings.
Using a Stratasys J750 PolyJet printer, designers were able to add polymers to textiles. For Stratasys, the aim is to develop the fashion market and enable more than 500,000 combinations of colors, textures, and transparencies.
Amid the general euphoria about the opportunities presented by additive manufacturing, there are those who take a more level-headed view of the disruptiveness of the technology. According to Nigel Flowers, United Kingdom managing director of Sumitomo (SHI) Demag, for example, injection molding and additive manufacturing are more complementary to one another than competitors.
“While we cannot knock the level of innovation happening in the 3D printing space, in reality, additive manufacturing is not the universal panacea it’s made out to be. Right now, it continues to perform strongest for prototyping rather than mass manufacturing,” Flowers said.
The idea that 3D printers are about to overthrow traditional manufacturing techniques — including molding, forging, casting and even subtractive CNC manufacturing — is simply scaremongering, he said.
With additive manufacturing (AM), novel parts can be designed and built with optimized topologies, eliminating the need for machining individual pieces and then assembling them. Many are hopeful that this technology will benefit the environment through a decrease in the amounts of energy and raw materials required to make components in all sorts of industries.
The Additive Report discussed 3D printing and its place in sustainable manufacturing with MIT Professor Timothy Gutowski, head of the university’s Environmentally Benign Manufacturing (EBM) research group. EBM focuses on examining the environmental effects associated with manufacturing products.
Additive Report: Can you provide an overview of the benefits of 3D printing in terms of sustainability?
Tim Gutowski: Any benefits depend a lot on the details. For lifecycle analysis claims, you’re setting up some version of additive manufacturing versus some version of a conventional manufacturing process. And one problem is that we have a better idea of the waste numbers for conventional manufacturing processes than we do for additive, because the latter is still a work in progress.
