AM is a relatively new means of producing goods, yet has become incredibly popular around the world in a very short amount of time. More commonly known as 3D printing, AM takes raw materials in liquid form and essentially prints a component, product, or part – layer by layer. This technology has been used around the world for myriad applications from houses to, controversially, guns.

In manufacturing hubs like Vietnam, this new technology has the potential to be a changemaker. It can produce parts and components for a fraction of their traditional cost, by limiting wastage and reducing the need for labour. 

With this in mind, the potential for AM to dramatically disrupt the manufacturing industry is clear and as a result, drew significant attention in Vietnam. This is in both using AM in production processes and in developing AM technology. 

In this light, it’s not only important but can be valuable for manufacturing firms in Vietnam to understand the key industry drivers of AM — how the industry is developing, and what impact AM might have on Vietnam’s enormous manufacturing industry.

The post How Additive Manufacturing Revolutionises Malaysia’s Automotive Industry appeared first on Asia Pacific Metalworking Equipment News | Manufacturing | Automation | Quality Control.

Standard manufacturing methods lost their traction to advanced ones for profitability. Hybrid manufacturing combines two or more distinct processes in a single piece of equipment.

There are several types of hybrid manufacturing, although the most common combines laser additive manufacturing (AM) and 5-axis machining processes. The paper reviews hybrid manufacturing and analyses various AM processes, including binder blasting, directed energy deposition, material extrusion, material jetting, powder bed fusion, sheet laminating, and vat polymerization, and their sub-classifications.

It also highlights the importance of 5-axis machining in hybrid manufacturing. integration between additive and subtractive processes, the challenges faced, and future opportunities.

1. Additive Manufacturing (AM)

AM enables producing 3D geometric parts through layer overlay. However, high costs resulted in low adoption. Hence, 5-axis machining is used, enabling a single configuration to machine five sides of the part, resulting in high accuracy and surface quality.

A flexible, sophisticated yet challenging technology, AM uses wire or powder as raw material, and the part is produced based on a computer-aided design (CAD) project’s geometry.

The post Hybrid Manufacturing Processes Used Producing Complex Parts (Part 1) appeared first on Asia Pacific Metalworking Equipment News | Manufacturing | Automation | Quality Control.

by Benny Buller

More than any other AM technology, the expectations and promise of metal AM were the highest. However, that promise was broken and metal AM fell short of expectations. Rather than design freedom, engineers faced design restrictions and were forced to comply with the limitations of conventional AM systems.

Meanwhile, most suppliers of AM technology have put the onus on engineers to design around its limitations, rather than build AM solutions that could fulfil the original promise. This was done by introducing design for additive manufacturing (DfAM) as a requirement for building parts. 

All engineers have a deep understanding of the critical value of DfX—X could be manufacturing, service, cost, obsolescence, reliability, or some other requirement. X stands for the real world. Engineers cannot just design for function—they must design for the challenges of reality.

Only then can those designs be implemented in the real world, with all its imperfections and practical limitations. Knowing how to embed DfX in their designs is what separates the engineering professionals from the amateurs.

However, the AM in DfAM is not just another variable of the X in DfX, and we must be careful not to confuse the two. AM limitations cannot be confused with “just another aspect of real life.” AM is a limited manufacturing technology, it has an inherently high-cost structure, it has much lower accuracy than machining, it produces lower quality surfaces, and it is not trivial to qualify its material properties.

The only reason to use AM is that it allows an unprecedented degree of design freedom. But for AM to establish itself and expand its adoption, as well as to make good on its original promise, the design freedom it provides must be incomparable to any other manufacturing technology.

Replacing the limitations of CNC machining with a new set of geometrical limitations and expecting engineers to start aligning their imagination around those new limitations is naïve and self-centred. AM must demonstrate how it provides value in a massive way before it can expect engineers to design according to its limitations.

The compromises that DfAM introduces include adding supports, changing geometries, and making other modifications that meet the restrictions of AM so the part can be produced. These compromises don’t just impact the manufacturing of the part, they alter performance, impact reliability, and require excessive post-processing. Most importantly, DfAM as we know it compromises the design intent of the engineers building the parts.

AM, specifically laser powder bed fusion, can deliver exceptional benefits in terms of performance for the parts it’s used to manufacture. However, DfAM tells engineers that to adopt the new technology they also need to adopt a new design methodology to overcome the restrictions of most AM technologies.

For most engineers, this is a non-starter. In the words of Joris Peels at 3Dprint.com, DfAM is like making people learn Italian before they can eat pizza.

DFM is essential but should not be conflated with DfAM. You don’t want engineers to design parts in a vacuum. Even if they are great ideas, they are more likely to fall flat in the real world. But for AM to reach maturity and increase its addressable use-cases, we need to unlock design freedom rather than restrict it through DfAM.

The post SLM Solutions’ Next Disruption In Additive Manufacturing Vows To Impress appeared first on Asia Pacific Metalworking Equipment News | Manufacturing | Automation | Quality Control.

Gregor Reischle

Dedicated standards for medical devices produced using Additive Manufacturing are already in preparation. In future, they will smooth the path for the implementation of new technologies as well as their assessment for approval. In this interview with Asia Pacific Metalworking Equipment News (APMEN), Gregor Reischle, Head of Additive Manufacturing at testing, inspection and certification services provider TÜV SÜD, shares what aspects need to be considered against this backdrop.

Why do we need standards to help us use AM technology for medical production?

Gregor Reischle (GR): Items that are already produced using Additive Manufacturing, such as protective face coverings, masks and visors or products for radiation treatment, are subject to particularly rigorous conformity and safety standards. However, assessment procedures for approval of these products take time – and time is of the essence in a pandemic. Standards help to ensure regulatory requirements are implemented reliably, promptly and cost-effectively, thus minimising risks. They also represent state-of-the-art solutions and serve to concentrate specific knowledge.

There are still no Additive Manufacturing standards designed specifically for medical devices. Where can manufacturers seek guidance in the meantime?

GR: We have drawn up checklists for all the most important requirements in the main standards and regulations relating to Additive Manufacturing, covering those that set out more general terms as well as the first more specific requirements. We are currently providing the checklists free of charge International standard organisations such as ASTM International and ISO are likewise providing access to relevant standards free of charge at the moment, for items such as personal protective equipment and medical devices. This benefits testing laboratories, healthcare specialists and the general public.

How widespread are 3D-printed medical devices?

GR: Conventionally manufactured products still make up the majority. Anyone using 3D printing today is pursuing strategic aims and is willing to invest a lot of time in such products. Additive manufacturing is only widespread in specific areas of medical engineering, like prosthetics and dental technology. In fact, probably all the major manufacturers in the dental industry now supply 3D printers, some of which can even be used in medical practices. 

What changes will the MDR introduce in this respect compared to its predecessor, the MDD?

GR: Under the Medical Device Directive (MDD), these “custom-made products” can be used without the need for CE marking. Although the same will apply under the Medical Device Regulation (MDR), manufacturers of class III implantable custom products will now need to call in a Notified Body to perform conformity assessment of their quality management system. Many products will fall into a higher class under the MDR, and this may require the involvement of a Notified Body in some cases. Custom-made products will be replaced by a common basic model which is customised for patient-specific use.

How will upcoming standards support the requirements to fulfil regulatory requirements such as MDR conformity? And which existing standards could already be useful?

GR: The requirements of the MDR state that a Notified Body must assess the manufacturer’s quality management system and verify compliance of its processes with the state of the art. DIN SPEC 17071—the specification for requirements concerning quality-assured processes at additive manufacturing centres—can usefully be applied here. The guideline is aimed at minimising risks stemming from parts and components produced using Additive Manufacturing, irrespective of the industry or sector. A project to transfer these findings to medical engineering is already under way, and a white paper on the subject will be published very soon. The DIN SPEC 17071 will also be advanced to reach the international ISO/ASTM level; the upcoming ISO 52920 and 52930 represent state-of-the-art quality assurance for AM production.

“This breakthrough represents a major milestone in the development of aluminium for binder jetting and a significant step forward for the AM industry as it is one of the most sought-after materials for use in automotive, aerospace and consumer electronics,” said Ric Fulop, CEO and co-founder of Desktop Metal. “The global aluminium castings market is more than $50 billion per year, and it is ripe for disruption with binder jetting AM solutions. These are the best reported properties we are aware of for a sintered 6061 aluminium powder, and we are excited to make this material available exclusively to Desktop Metal customers as part of our ongoing partnership with Uniformity Labs.”

“The introduction of lightweight metals to binder jetting opens the door to a wide variety of thermal and structural applications across industries,” said Adam Hopkins, founder and CEO of Uniformity Labs. “This innovation is a key step towards the adoption of mass-produced printed aluminium parts.”

This new powder enables the sintering of unadulterated 6061 aluminium and represents a significant improvement over prior techniques used to sinter aluminium, which required coating powder particles, mixing sintering aids into powder, using binders containing expensive nanoparticles, or adding metals such as lead, tin and magnesium. Critically, the powder also enables compatibility with water-based binders and has a higher minimum ignition energy (MIE) relative to other commercially available 6061 aluminium powders, resulting in an improved safety profile.

Desktop Metal and Uniformity Labs plan to continue to work together over the coming year to qualify the powder and scale production for commercial release. Once fully qualified, Uniformity 6061 aluminium will be available for use with the Desktop Metal Production System platform, which is the only metal binder jetting solution with an inert, chemically inactive processing environment across the printer and auxiliary powder processing equipment, enabling customers to achieve consistent, high-quality material properties across volumes of end-use parts with reactive materials, such as aluminium.

For decades, most 3D printers adopt a closed system—where the user is restricted to the manufacturer’s resins. Economically, this means that chances are, the material is costlier as the manufacturer has the bargaining power over the user, who is restricted to their material offerings. For the same reason, it could also mean that users are unable to create something that is eco-friendly, unless the material is certified to be so. 

But most importantly, this limits the creativity of the individual to come up with a product with the best design paired with the ideal material. Of course, closed source printers aren’t all that bad, they ensure that the quality of the end product is up to standard, by ensuring that their materials are of quality.

However, with the invention of the open-source 3D printing technology, the woes of product designers have been resolved. The designer now has the power to choose any material from any supplier based on their personal preferences. Want a cheaper material? Find an economical supplier. Want an environmentally friendly product? Find a supplier with green or eco-friendly resins or filament. Want a malleable product? Find a soft polymer supplier. 

All in all, this means that designers are free to create whatever they have in their imagination. This has become a new norm over the years as more and more designers search for alternatives from closed-source printers to bring their imagination to life. As such, over the years there has been a surge in open-sourced 3D printers, particularly desktop ones, to meet the needs of the users.

Why is it Important for the Aerospace Industry?

3D printing has become especially important in the aerospace industry to address challenges like production time, cost of production and carbon emission. For example, it can produce lighter parts while maintaining strength, which reduces the aircraft’s overall weight, hence lowering its fuel consumption. This in turn, cuts operational costs and lowers carbon dioxide emission. Here are other benefits of 3D printing for the aerospace industry: 

Precision 

Surface finishing is critical in the aerospace industry. 3D printing parts can be post-processed to a very high precision. Technologies like Material Jetting are able to produce parts with smooth, injection moulding like surface finishing with little post processing needed. While Selective Laser Melting (SLM) is able to produce high performance metal parts. 

Materials That Are Licensed 

Currently, there are many qualified materials used in producing parts in the aerospace industries, depending on the technology. In SLM, Aluminium or Titanium are mainly used. Examples of parts printing with SLM are the suspension wishbone and the Jet engine. While in Selective Laser Sintering (SLS), Nylon is the preferred material. Examples of parts printed with SLS include Air flow ducting and Tarmac nozzle bezel. Other technologies include Stereolithography (SLA) and Material Jetting, which uses Resin to produce parts such as Entry doors, brackets, and door handles.
