3D printing is buzzing trend these days. If you are not up to speed with the trend, you probably should. Because it changes everything around. Start today from Wikipedia article about 3D printing (aka as additive manufacturing). Today’s announcement about GrabCAD acquisition by Stratasys- leading 3D printing company is another confirmation about important role additive manufacturing will play in the future. The following video is a recording of Autodesk CEO Carl Bass about 3D printing topic – The future of how things are made.

3D printing is changing the way we are going to manufacturing products in the future. This is, of course, very high level statement. It is interesting to go down and see the impact in bits and bytes. For example, how it will impact product structure, or how it will impact product data management or manufacturing planning. You probably don’t associate these two things, but additive manufacturing is changing the product structure and everything that related to that. It certainly impact BOM management too.

My attention caught by the following Engineering.com article – Autodesk and Local Motors Collaborate on First Spark 3D Platform Implementation. The article speaks about collaboration between Local Motors and Autodesk about first large scale industrial implementation of Spark. I found the following passage quite provoking:

According to Local Motors, the Strati simplifies the automotive assembly process and is a result of leveraging the contributions of community, advanced manufacturing tools, and software, like the Spark platform. This could bring many advantages, including reduction in the number of parts in a vehicle’s Bill of Materials (BOM) from 25,000 components to less than 50. The on-demand nature of 3D printing means that automotive manufacturers can change aspects of their design—or even come up with an entirely new one—with little or no additional cost in tooling or time.

The complexity of modern car is skyrocketing. Hardware is part of a complex one element of that. Others – electronic, software are playing significant role. In the past car was a pure mechanical beast. Today, it is a combination of hardware and software on wheels. Who knows, maybe in few years, we will see car bill of material very similar to computer today – few mechanical pieces and lot of software. With changing balance between hardware and rest of car elements, the focus can shift towards multi-discipline product structure.

What is my conclusion? The complexity of products is changing. It is important to see trends. While overall complexity of manufacturing products (cars included) will grow, we might see a decrease in manufacturing complexity of hardware as a result of new manufacturing methods – additive manufacturing (3D printing) will pay a key role here. At the same time, the complexity of multidisciplinary product structure (BOM) will grow. Just my thoughts…

3D printing, GitHub, and PDM erosion

January 4, 2013

3D printing is still a narrow niche play zone. In my view, we are not going to see 3D printer at every home soon. At the same time, manufacturing companies and larger service vendors are getting more and more interested in the 3D opportunity. As it happens with regular printers and scanners in offices, these resources are often shared and can be used by more than one person in a company. Looking back, print management and remote printing utility or service was one of the most requested functionality in early EDM/PDM systems. Guess what? The same is going to happen with 3D printing nowadays.

The following article caught my attention earlier today – GitHub Codes Up Computer-Less 3-D Printer Software. For those of you not aware, GitHub is hosted document revision control system. According to Wikipedia: GitHub is a web-based hosting service for software development projects that use the Git revision control system. GitHub offers both paid plans for private repositories, and free accounts for open source projects. As of May 2011, GitHub was the most popular open source code repository site.[3] In other words, if you are software developer, the change you and/or your team will end up using GitHub for source control management is pretty high.

The problem is that 3D print job takes a lot of time. You don’t want to hook your computer and keep it busy with this job. Remember old pen plotters 20 years ago? The problem is exactly the same. According to the article, GitHub will provide a service to send print jobs to 3D printer remotely. Here is the quote:

GitHub, the popular and well-funded version-control company, is entering the 3-D printing market. They aren’t jumping into the world of hardware (not yet at least), but instead are automating tedious workflow issues, namely printing parts without leaving a laptop tethered to the 3-D printer for hours at a time. Their solution, called Make Me, allows users to push files to the MakerBot via HTTP and monitor the build process via webcam.

However, I found the following passage even more interesting.

The tool itself is a handy utility, but it also helps illuminate GitHub’s corporate culture. “We tend to do these internal hacks/projects in three stages,” says Zach Holman, a developer at GitHub. ”Get something cool (new technology, 3-D printer, what have you); hook it up to a rudimentary service that we can interact with through Hubot, our chat room robot; build on top of it and do something pretty awesome we couldn’t really predict in the first place. So, from that perspective, we’re on stage two. Curious to see what’ll happen in the future (if anything!)”

It made me think beyond "remote printing" idea. Software is a significant part of every manufactured product these days. Mobile phone, automobile and aircraft are containing huge amount of software code that needs to be managed by development and engineering. To manage software versions is one of the requirements we started to hear more and more during PDM/PLM implementations. PLM vendors are starting to pay attention to that. Take a look on PTC/MKS acqusition or TeanCenter mechatronic process management.

What is my conclusion? Business environment is changing very fast these days. Proven open source software combined with some good ideas can provide a good foundation for new innovative projects. How long will to build some PDM rudimentary services for GitHub to provide a solution to small manufacturing firms management 3D CAD and software design project? Probably not much and it can become a holiday or summer time project for one of GitHub developers. PDM/PLM vendors can discover a new competition coming from unusual and unexpected direction. Just my thoughts…

PLM and 3D printing revolution

March 15, 2012

3D printing is an important and cool trend these days. For those who are not in the business of 3D Printing, navigate to the following wikipedia article to close the educational gap.

3D printing is a phrase used to describe the process of creating three-dimensional objects from a digital file using a materials printer, in a manner similar to printing images on paper. The term is most closely associated with additive manufacturing technology, where an object is created by laying down successive layers of material.[1] Recently the term is increasingly used to describe all types of additive manufacturing processes, or even other types of rapid prototyping technology.

It started almost 10 years ago, 3D printing became much stronger and considerably cheaper lately. I’ve been monitoring multiple publications and announcements related to 3D Printing. You can navigate to few of them – The silent revolution – 3D printing in the workplace and the home by Develop3D, 3D color printing as common as a wooded lot tick infestations. it’s coming by SolidSmack and few more.

The last one that caught my attention yesterday was Playing the 3-D printing revolution by By James Saft (Reuter). Have a read. The following passage was my favorite:

If it takes off, it could radically change global trade flows, delivering a huge boost to the indebted and aging developed world, while threatening the fundamentals which underpin manufacturing success in China and some other emerging markets. 3-D printing is a process under which highly customizable products are literally sprayed into existence using something not too dissimilar from an ink-jet printer. Originally used mostly to provide build prototypes, it is now being used for actual production, notably by a unit of EADS which is working on developing 3-D printing-produced aircraft parts. The advantages are huge: easier customization, lower labor costs and, potentially, a severing of the reliance on a supply chain, a feature of manufacturing since the days of Henry Ford.

You may ask me – what is the relationship to PLM? Here is my take. If EADS is working on how to develop 3-D printing produced aircraft parts, it is going beyond toys and exhibition souvenirs. If so, companies will have to apply some production flow and decision-making processes to make it efficient and cost-effective. It also opens an additional market for supply chain relationships for businesses to specialize in operating and maintaining 3D printing facilities.

What is my conclusion? 3D printing revolution can change lots of stable manufacturing relationships. Moving from one state to another will require some new processes in place to make it happen. Another wake-up call for PLM vendors and opportunity for new businesses. PLM perfect storm is coming. Just my thoughts…
