Q&A With Davide Sher on Automation of Additive Manufacturing

The follwing data points are sourced from the SmarTech report, “MARKETS FOR AUTOMATED 3D PRINTING: 2016 TO 2027:  AN OPPORTUNITY ANALYSIS AND TEN-YEAR FORECAST“

What is the role of 3D printers in tomorrow’s automation production lines?

3D Printers are expected to play a key role in the evolution of the digital factory, eventually providing means to further streamline and automate the manufacturing process.

Why is automation becoming a key issue in AM today?

Over the past two years, as 3D printing began to shift from a process used for prototyping and small batch technology to a large batch and mass customization production technology, all major industrial 3D printer OEM’s have begun to pay closer attention to integrating their systems both within 3D printer networks (or “farms”) and within automated production lines.

How much is the overall landscape for industrial automation worth and how much of this will be related to 3D printing?

The overall market for automated factories in the Industry 4.0 is expected to grow from $182 billion in 2016 to $352 billion in 2024. A very significant portion of this, roughly $45 million by 2024, will be represented by PLM (Product Lifecycle Management) software.

SmarTech Publishing expects the market for automation in AM to represent a very significant revenue opportunity, growing to $11.2 billion by the end of the forecast period at an overall 35.98% CAGR from the 2017 level ($518 million).

How much can 3D printed be further automated and how?

There are three levels at which automation can be implemented in an AM factory or production plant within a complete workflow.

  • Process Automation
  • Part and Material Handling Automation
  • Workflow Automation

 

Which are some of the key technologies and OEM’s visions for AMA (additive manufacturing automation)?

Several large 3D printer manufacturers have announced and displayed their vision for automating production in an AM based factory. Among those closest to integrating AM into an automated workflow are the large machine tool manufacturers. One of the very first industrial 3D printer OEM’s to devise a vision for automating 3D printing factories is Germany based Concept Laser with its “Factory of the Future” concept. Concept Laser was acquired last year by GE and will continue to build on this concept as its systems are implemented for actual part production within the GE group. Polymer 3D printing market leader Stratasys is working on three different solutions which look toward further automation of FDM (thermoplastic extrusion), its end-use part production 3D printing technology. By comparison, its advanced polyjet technology is seen (and expected to remain for the foreseeable future) primarily a prototyping process.

While photopolymerization has only been considered a production technology for a very limited number and highly specific type of products – such as hearing aids – recent advancements in both technologies and materials have contributed to the technology’s evolution into a full production process, thus increasing the need for automation. Carbon is leading the way with its high-speed CLIP technology infrastructure.

OEM’s Concepts:

 

What is the overall outlook for automation of polymer AM hardware?

Sales of automated and automation-ready polymer-based 3D printers are expected to increase significantly over the next ten-year period, driven by widespread adoption of high-speed “planar” technologies, which can achieve printing speeds 10X higher than standard systems. These technologies cover both powder bed fusion (PBF) and photopolymerization processes. The overall market opportunity for automated polymer AM hardware is expected to reach $3.172 billion by 2027 with 45.62% CAGR from 2017. The overall revenue opportunity for automated metal AM hardware is comparable, with yearly sales expected to top $3 billion by 2027, growing at 32.42% CAGR from the current 2017 levels.

What are the other key elements in the AMA workflow?

Since this report focuses primarily on mechanical automation of the AM process, robotic systems play a significant role, both in some of the processes (3D printers are robots as well) and – perhaps more importantly – in the intermediate part handling stages which connect the different stations within the entire production workflow. Automation of material handling is a must for the future of AM as mean of production. Workloads for operators are expected to increase significantly with part size capabilities, as the powder-filled modules can already weigh several hundred kilograms. The post processing phase currently represents one of the most significant bottlenecks in the automation process however it is also undergoing some of the most rapid evolutions in terms of automation, especially in the realm of polymer powder bed fusion based technologies. The automated AM factories of tomorrow are also likely to integrate advanced automated metrology, inspection and 3D vision solutions in the production flow. Due to the high average costs of these systems, they represent a significant revenue opportunity.

What types robotic interactions will take place in tomorrow’s AMA factories?

Companies will, in the future, be concentrating on the collaboration of human and machine, simplified applications, and light-weight robots. Added to this are the two-armed robots, mobile solutions and the integration of robots into existing environments. There will be an increased focus on modular robots and robotic systems, which can be marketed at extremely attractive prices. Robotic units are expected to connect multiple processing stations. These will be either based on multi-axes robotic arms (mainly for extrusion technologies) on rails or autonomous robotic carts (mainly for powder bed technologies).

What is the outlook for metal AMA?

The overall revenue opportunity for automation units in metal AM is expected to near $1.4 billion by the end of the forecast period, growing at 37.37% CAGR for the 10-year period. The overall market for automated stations and robots in polymer AM is expected to top $3.1 billion by the end of the forecast period, growing at 35% CAGR between 2017 and 2027.

What will tomorrow’s AMA factories look like?

The evolution of 3D printing factories within the scope of this report identified structures which are expected to hold a maximum of 20 to 30 systems. In the first half of the forecast period, the great majority of internal AM production departments and AM service bureaus, even those working toward automated batch production, are expected to have less than 10 systems and thus much smaller surfaces to cover for data transmission.

What is the role of software going to be?

In this report SmarTech Publishing is focusing on process and mechanical automation. This means that the software analyzed in this section is used either for running the AM process (and the other related processes that were examined in the previous parts of this report) or the production line. In the world of advanced manufacturing the term MES to describe software based Manufacturing Execution Systems is already fairly common. However, it is only now beginning to be introduced to AM, leading SmarTech Publishing to coin a new acronym: AMES.

What types of software will drive AMA?

Software is an integral part of AM automation, not only for managing the product’s lifecycle but also for establishing a digital factory environment while managing and controlling the actual process and production workflow. SmarTech Publishing’s forecast for automation software in AM covers four main segments.

  • Networking
  • Simulation
  • Process
  • Production

 

What is the overall outlook for software in the AMA workflow?

SmarTech is estimating the overall value of software for metal AM automation forecasting the overall segment to grow to $353 million in yearly revenues by 2027, growing at 25% CAGR from the current 2017 levels. The revenue opportunity for software in polymer AM automation is also expected to represent a very significant and highly profitable opportunity, totaling $172 million in yearly sales by the end of the forecast period, after growing at 29.5% CAGR between 2017 and 2027.

Industry 4.0 Will Not Occur Without AM Workflow Automation

From Davide Sher, 

SmarTech just released my latest AM market report, this time on AM workflow automation, that is automation of the AM production line. In this report, I tried to assess what the overall business volume could attain from the establishment, within tomorrow’s automated factories, of the fully digital production line which use AM as the core production process in an end-to-end production cycle.

For this report, I only considered automation of the mechanical processes involved. In other words that part of digital manufacturing that takes the product from a digital file ready to be 3D printed (so after it underwent CAD, CAE and CAM software processes) and before the distribution and retail phase (which is managed by CRM and ERP software).

While the creation and commercialization processes are well on their way to be fully digitalized in the Industry 4.0 concept, the part which I analyzed and researched in this report is the least digital today. Even with a potentially pure digital process like 3D printing at its core, the manufacturing process is the most labor intensive so it is the primary bottleneck in a more streamlined, efficient and sustainable idea of production.

Within this process exist several different phases and levels where automation could be implemented. In some cases, the means to do it already exist and simply need to be assigned or programmed for specific tasks, in other cases, they still need to be developed. However, in all cases, it appears clear that most 3D printer manufacturers have become aware that – as AM becomes a more efficient mass manufacturing or mass customization platform – the 3D printer is no longer a stand-alone system but needs to be integrated into so-called “production cells” or “end-to-end digital production lines”.

These production lines include several different stations – which can also be integrated into single systems – with automation occurring at three different levels. One is of course software, where MES (Manufacturing Execution Systems) software, such as Materialise Streamics and Authentise, are being optimized for AM. Others take place within the different processes (3D printing, material handling, post-processing, finishing) and in the overall AM workflow automation, with robotic systems and electronics (sensors and networks) acting to connect the different stations.

Every major company is working toward this goal, both in polymer and in metal AM technologies. Some more than others. Concept Laser, for example, has outlined a clear vision for the fully automated factory of tomorrow – which provided a base for my own research in this field. Other metal AM system manufacturers such as Renishaw and Additive Industries have introduced production systems which provide integrated and automated powder sieving and resupply, thermal treatment and even part handling. EOS also provides solutions for both process and workflow automation, while major DED system manufacturers like DMG Mori and Trumpf are simply implementing current machine tool automation practices to the include the metal laser deposition engines.

In polymers, the stated intention form new entries HP and Carbon to target production through high-speed laser technologies has been driving current PBF and photopolymerization market leaders like EOS and 3D Systems to focus more on optimized and automated workflows and new systems. At the same time, established low-cost system manufacturers such like Formlabs (for SLA) Ultimaker, Lulzbot and MakerBot (for filament extrusion) are building automated production cells and networked 3D printer farms which contributed to driving Stratasys to build three different solutions employing robotic arms and multiple 3D printing engines for increased automation and production rates through 3D printing. Many of these automated solutions are run using Siemens software, with the PLM software giant actively partnering with AM companies to further develop automation capabilities in the AM process.

In the report, I began with SmarTech’s extensive and consolidated database of yearly 3D printer sales and estimated the number of systems which are going to be both process and workflow automation ready. My research, which included conducting interviews with some of the major players in this area, enabled me to estimate the size of tomorrow digital, additive, automated factories. I conducted interviews with and gathered information from Concept Laser, Carbon, Desktop Metal, HP, Stratasys, Materialise, Post Process Technologies, Kuka. Using this data, I assessed the number and overall revenues deriving from the robotic and electronic systems which will be necessary to run these factories. Finally, leveraging SmarTech’s AM software sales database and interviews with market leaders and experts like Siemens’ Ulli Klenk and Authentise’s André Wagner among others, I assessed the market for the software that will increasingly be used to run these processes.

Summing up all these factors I expect the market for AM automation to grow from about $500 million today to just over $11 billion ten years from now. The biggest revenue segments will be metal and polymer 3D printers, especially the PBF ones, with robots (for both metal and polymer workflow) also representing a significant share of the market. Software will be a strong driver as well, while the cost of electronics (without including computers and servers) is surprisingly low since the overall numbers of machines and size of the factories is still expected to be far from that of current mass manufacturing.

IoT and Industry 4.0 solutions are being implemented in several segments of industrial manufacturing. By integrating AM into the digital production workflow this level of automation could reach new heights. AM cannot evolve without automation and no factory could ever be fully digital without integrating the full voxelization of matter and products.

Progressing Orthopedic Implants with Additive Manufacturing

Looking back over the last decade, it is clear from the vantage point of 2017 that additive manufacturing (AM) has caused significant disruption in the medical sector. Indeed, in no other sector has AM had such a profound and dramatic effect on the human condition in terms of improving lives — whether directly at the point of need within clinical environments or communities or indirectly as a manufacturing method for greatly improved medical devices. Currently, despite the direct approach dominating many ‘3D Printing’ headlines as surgeons and clinicians increasingly embrace the AM systems at the point of need for patient-specific applications, it is the latter, indirect approach, that has seen significant results for higher volume, serial production with AM by medical device manufacturers.

Materialise World Summit 2017 Focuses on AM for Production

SmarTech Publishing Senior Analyst, Davide Sher recently attended the Materialise World Summit in Brussels recently. His notes from the event.

Recent significant investments pouring into the industry from large corporations, including the software and technology powerhouses such as Siemens, Dassault Systemes, SAP and more, have accelerated the transition for the use of AM technologies in serial production. Large 3D printing bureaus turned “additive factories” like Materialise are amongst the companies that are best suited to exploit the new opportunities that are emerging. The recent Materialise World Summit held in Brussels showed how the Belgian company is looking to work with all its partners to further accelerate and complete this transition, starting from major adopting segments such as aerospace, automotive and medical applications.

The global conference that the leading European 3D printing factory organizes every two years or so (which is roughly the rate at which AM technology doubles in terms of capabilities) brings together some of the most relevant manufacturers and adopters of 3D printing worldwide, both as speakers and participants. Companies like Airbus, GKN, GE, Dassault and SAP showed off some of their achievements in the “industrial AM track” while top medical professionals gave the audience an idea of what is possible today in the “healthcare AM track” of conferences.

Compared to the event held in 2014, the number of conference tracks was reduced from four to two. The 2014 event, however, came at an exceptional time – with Materialse soon to become publicly listed on the NASDQA index – and the content provided was even too abundant for everyone to fully benefit from it. The (justified) high price tag of this latest edition of the conference, which still offered some of the most advanced and updated content available on the latest evolutions of AM, was meant as a way to select an audience that focuses on 3D printing as a truly cost effective mean for advanced manufacturing applications.

The two-day event also included a “networking” area where conference sponsors, Materialise partners and internal Materialise divisions showed off some of their 3D printing capabilities and products. These ranged from the Bicicletto futuristic e-bike from Italian company SPA to 3D printed parts form EOS, HP and Concept Laser, to advanced 3D printing materials from BASF and DSM.

The initial plenary session was kicked off by Materialise founder Wilfried “Fried” Vancraen, who made an assessment of the past decade – and the relative Materialise conferences that took place over that time period – during which a $1 billion industry grew to become a $6 billion dollar opportunity, on the road to exponential growth. During the initial plenary session. Jonathan Morris, from US-based Mayo Clinic supported this theory with clear examples of what they were able to achieve through 3D printing in their respective fields.

Materialise, and its industry leading suite of AM software, have focused on the implementation of AM in the healthcare industry for the last two decades. 3D technology has been used in applications from designing and producing custom devices and instruments, to planning complex clinical procedures and training future medical professionals more effectively. Several more successful cases for implementing 3D technology into production for the healthcare segment were highlighted, with a specific focus on metal implants (CMF in particular) and polymer based prosthetic and support applications.

The industrial track of conferences focused primarily on how additive manufacturing has demonstrated its ability to transform supply chains, business models and even entire industries. The themes of the conference revolved around how implementing AM in production means understanding a delicate interplay between several factors which include application, scope of the technology, design options and 3D print software. A particular focus was placed on using next generation CAD software for designing topology optimized, generative structured specifically for AM.

The over fifty speakers spread across a two-day period spoke on behalf of industry pioneers in segments ranging from actual 3D printer and 3D software production to include both industrial and even consumer product applications. The main industry experts were also invited to attend, with the first day culminating with an evening gala, held in the exclusive Concert Noble location in Central Brussels. Here Fried Vancraen took the opportunity to thank all those that have worked and are still working the company to “materialize” the founder’s dream of custom, optimized sustainable industrial production through AM.
