Realize Featured Client: ICS

Hydraulic Housing, A60 Resin and cast 316 stainless, side by side.

Realize CLient Profile: ICS/Girard

We help ICS and Girard Equipment by providing them with QuickCast patterns created from one of our SLA machines. This type of work is unique from a standard SLA job because in the end, the pattern will be used to make a metal part. These individual SLA patterns are used by foundries as part of a process called investment casting which will produce one metal part for every SLA pattern used. More specifically, the work we do for Girard helps them create short run metal prototypes for the tanker trailer industry and when they reach out to us we are able to supply them with fast turnaround, high- quality QuickCast patterns. We asked ICS Foundry Manager Bill Laiacono a few questions about the industry and how they use additive manufacturing for their business.

Tell us about your business.

ICS is a captive foundry, supplying stainless steel investment castings to Girard Equipment, Inc., manufacturer of vents and valves for the bulk liquid transport industry.

How do you use 3D Printing/Additive Manufacturing/QuickCast to help with your projects?

Mainly prototyping. With the help of Realize, Inc., we can take a part from idea to cast and machined stainless steel in less than a week.

What is your overall feedback about our services and are there any examples of how Realize has helped your business?

Every interaction with Realize, Inc. has been a positive one. Realize has always been responsive, quick to produce and very reasonably priced. Customer service is pleasant and accommodating too.

How can Realize can help your business in the future?

By simply providing the same quality, value and responsiveness we have come to expect from Realize.

Why do you think there is such a growing buzz about the 3D Printing/Additive Manufacturing industry?

The diversity and range of 3D printing has grown immensely. Because of 3D printing, items can now be realized in a matter of hours that used to take weeks. The results are almost instant.

What is something that you personally would like to have 3D Printed?

Realize Featured Project: Fogo Ultimate Adventure Gadget

It’s always exciting to work on new projects that have the potential for coolness like the new Fogo Ultimate Adventure Tool Gadget! Many times we are working on projects that get the entire Realize, Inc. team buzzing with enthusiasm, but we’re not always able to talk about everything we do, some projects are TOP SECRET. So it’s with great pleasure we share some information about this cool little gadget known as Fogo. We talked with Co-Founder Dustin Bouch about his new product.

Realize: Tell us about your product.

Dustin: The Fogo is an outdoor device that combines a GPS receiver, powerful LED flashlight, digital walkie-talkie, and USB back up battery. It helps keep outdoor enthusiasts safe and lightens their load.

How did you use Realize and 3D Printing to help with you project?

We utilized Realize to prototype all the plastic components during the development phase. This included a couple snap fit parts and a light guide that Realize did a great job of polishing and clear coating for us to make it 100% functional. Realize gave us great parts with a fast turnaround time.

How do you think you will use additive manufacturing in the future and are there any new directions or capabilities you would like to see in the industry?

We will continue to use 3D printing to support our development efforts for the foreseeable future. We look forward to seeing stronger materials.

What were the biggest challenges with creating the Fogo Adventure Gadget?

Our biggest challenge was packaging a lot of parts and electronics into a small envelope. We also have some tough constraints for durability and waterproofing that required a lot of effort in analysis, iterative design and testing.

With such a cool product coming out is there a follow up idea you have ready to go?

The Fogo has an interchangeable component capability that we call the SmartCap. It allows the user to swap SmartCaps on and off the device to add hardware capability and configure the device for different activities. For example, the walkie-talkie is actually part of a SmartCap, so our customers can either buy the Fogo now with the walkie-talkie functionality or buy it and plug it in later down the road. We have immediate plans to make additional SmartCaps such as a Satellite Modem SmartCap, Avalanche Beacon SmartCap and Laser Range Finder SmartCap.

What is something that you personally would like to have 3D Printed?

I would love to 3D print a replica of my dog Lou! He is a 20 pound terrier poodle mix and it would be amazing to have a little statue of him in my house to torment him with!

Where can people get more info on the Fogo?

We are running a Kickstarter campaign so we can raise money to get the Fogo out on the trail. Please check out our Kickstarter page

Realize Featured Project: 3D Printed Airplane Wing

NLF0414_Line

Realize, Inc. has been helping with the development of some very cool aerodynamic parts for the University of Illinois At Urbana-Champaign. We talked with Aerodynamics professor Phillip Ansel about the most recent wing project.

 

The Realize Featured Project: The 3D Printed airplane wing

 

Realize: Why are you making airplane wing prototypes? 

Phillip: We have started using rapid prototyping for creating wing and airfoil (the cross-sectional shapes that wings are made from) models, which we then test in our subsonic wind tunnel. By taking these models and passing air over the surface in our wind tunnel, we are able to simulate what happens when these wing sections are placed in flight. We will typically use various sensors to measure things like force, pressure, or flow velocity on or around this model. We then evaluate these measurements to determine how the flow about the model behaves, and what this means for the performance of a given wing section.

My research group specifically focuses on unsteady flows. Most research in aerodynamics is typically focused on understanding the average behavior of a given geometry over time. However, the flows about certain aerodynamic bodies can also have contributions that vary or oscillate significantly as time goes on, even if the object itself is stationary. There are several aerodynamic phenomena that have very distinct unsteady components of velocity or pressure, and my research group seeks to identify new ways to utilize these unsteady contributions. For example, the amount of lift that a given wing can generate is limited by something known as stall. If the angle of incidence of the wing to the flow exceeds certain limits, that wing will start to produce less lift and much more drag. Perhaps more importantly, an aircraft with a stalled wing is much more difficult to control. As it just so happens, the amount of unsteadiness in the flow increases significantly as the wing stalls. By measuring and identifying this unsteadiness we can develop a system to predict an impending stall and use various methods to manipulate the flow in order to prevent stall from occurring.

Our most recently-developed airfoil model is specifically suited for this purpose. We created the model with an internal cavity where we can install a set of pneumatic valves that can be switched on and off at a high frequency. Compressed air is passed through these valves, which then follows a snaking pathway to a set of blowing slots on the surface of the airfoil model. This is where rapid prototyping is particularly useful, since manufacturing these blowing slots using other methods would be difficult to say the least. We also designed the model to allow specialized sensors to be mounted into the surface of the model, which allow us to measure the unsteady surface pressure. Based on what is measured from these sensors, we can identify an impending stall and control the flow around the airfoil by blowing air through the surface slots.

 

How often does your program use 3D Printing/Additive Manufacturing?

To date, I have worked with four different airfoil or wing models that have been 3D printed and tested in our wind tunnel facilities, and also have plans to develop more. We will typically have a specific experiment requiring a new model about every year or two.

What are the challenges you face when creating prototypes?

The most pressing challenge we have when using 3D printing to develop our models is material warping. This is most prominent in regions where the printed material is very thin. Over time the material actually begins to deform. If this occurs, we cannot use the model any longer since it no longer conforms to the original aerodynamic shape. We have learned quite a bit about how to design our models to prevent them from warping and are improving our design techniques with each new model that we make.

 

How do you feel 3D Printing will affect the aerospace industry in the years to come?

3D printing will absolutely have a positive impact on the future of the aerospace industry. Sometimes the most challenging aspect of building an aircraft or spacecraft lies in the fabrication of certain components. I think that 3D printing will allow us to explore new methods of creating aircraft and spacecraft components to be lighter, stronger, and have improved capabilities. Moreover, I think that future aircraft and spacecraft will be able to use components that have been 3D printed on-site to allow for faster, easier, and cheaper repairs. This is already being explored on the International Space Station. Since space is so expensive and difficult to get to, astronauts are currently testing how 3D printing can be used on the ISS to help them with performing experiments and maintaining facilities.

 

What are the biggest challenges facing aerospace engineering?

Aerospace engineering is actually very diverse field that stretches across many organizations, disciplines, and objectives, so I can’t speak for the field as a whole. From my perspective, however, one of the biggest challenges facing aerospace engineering today is the speed at which we can feasibly adapt to new technologies and capabilities. The aerospace field moves extremely fast and new technological innovations are being developed increasingly regularly: so fast that it can be difficult for society to keep up. We are currently seeing this in the development of policies and established practices for UAVs and commercial space flight. One way that we can help to make these new innovations realizable in daily life is to encourage outreach and education about science and engineering to help people of all ages to understand what aerospace engineering is all about. By encouraging education and diversity in engineering we can increase the number of experts and quality of ideas in the aerospace field, making cutting-edge technology more realizable in society.

How do you inspire future leaders in your field?

I like to inspire future leaders simply by showing them how amazing the aerospace field is. There are so many interesting aerodynamic phenomena that happen in everyday life that we don’t always observe, but when they are pointed out to us we can’t help but be curious. I’m still blown away by so much of what I see in nature, and I think it’s incredible all that humanity has been able to accomplish with aerospace technology. In order to share this with my students, I like to incorporate real-world examples and demonstrations into my teaching. This can come through use of a vortex cannon to provide a simple demonstration of how vortex ring structures are formed to a classroom of students or incorporating modern research problems in the classroom.

Realize Featured Project: 3D Toilet

3D Toilet

3D Printed Toilet by Realize, Inc.

Realize Featured Project: The 3D Toilet

 

Here is a summary of this recent project from Realize, Inc. General Manager Brian Cazzell:

 

“The client needed a working SLA model of their toilet design to use at a trade show. The primary requirement was that it needed to be clear in order to demonstrate water flowing through the internal channels. Due to the platform size restraints of the SLA5000 machine, we needed to build the model in sections and create an inter-locking structure that when bonded together would maintain a water-tight seal for the duration of the trade show. The model also needed to be completely free of support material not only for aesthetic purposes but also to allow the water to flow freely through the channels. In the end, the client was very happy with the functionality and the overall fit and finish of this model.”

The Realize Q&A with Steve Griffiths

Steve_Griffiths1 2

Steve Griffiths – Sales Manager, Materialise

Materialise_IYCCO Realize, Inc is communicating with 3D Printing experts from around the globe to discuss the future of our industry. We talked with Steve Griffiths the Sales Manager at Materialise to get his take on where things are headed in the additive manufacturing world. Steve manages a team of professionals at Materialise who are selling and supporting leading software technology in the 3D Printing Industry.

“3D printing is an amazing industry with great potential. It’s a great combination of the machines, materials, software and the people. I’m excited to see where it goes!”

 

 

Why has 3D Printing become the buzz word for the entire industry and do you think that is a good or bad thing?

At first I resisted the move away from Additive Manufacturing and Rapid Prototyping. But as the term 3D Printing is allowing for a more consistent conversation about the technology through the mainstream press, and as it has been embraced by the public, catching their attention in a way that the other terms didn’t, I’ve decided to get on board and go with it as well.

 

There has been a ‘new generation’ of users exposed to AM/RP/3DP over the past few years, along with a huge media buzz.  How do you see this camp and the ‘old school’ camp coming together?
I think at first there will be lots of differences and levels of knowledge about the capabilities of 3D Printing. But as time goes on, the new generation will learn from the experienced users and in turn, the new generation will bring some fresh approaches that can inspire the ‘old guard’. What will be especially interesting is when students who are now being exposed to 3D Printing in their classrooms graduate and start putting the technology to use in ways that we can’t even dream of right now.

 

What challenges/opportunities do you feel service providers, like Realize, face today?

Service providers are facing lots of challenges in the industry today – with consolidations, pressure to reduce costs, and limited availability of materials probably topping the list. However, as a new generation of 3D printers are revealed, new materials are introduced to the market, and the software, such as the solutions developed here at Materialise, evolves to better answer the growing needs of the markets, we are also in an exciting time where people throughout the industry and constantly pushing the limits of what can be achieved. There are always challenges associated with emerging technologies, but it is the opportunities that make this such a great industry to be involved in.

 

What are some misconceptions about the capabilities of the technologies?

3D Printing is so mind-blowing to so many people that it is perfectly natural that there are misconceptions about what it can achieve – with people both underestimating as well as overestimating what is possible. For people who have only just discovered the technology and who have only seen the desktop printers now entering stores and schools, they think that it will still take years for the machines to reach a point where they can manufacture end-use parts, which has in fact already been possible for years using professional machines. On the other end of the spectrum, a common overestimation is that we are already at the point where 3D printed organs are possible and will soon be implanted in patients, which is still many years away. Instead, we should be celebrating the reality that we are already producing 3D Printed implants and have long been enabling a new level of personalized healthcare with printed medical models, virtual planning and printed surgical guides.

 

What are your thoughts on 3D food and clothing and all the headline grabbing stories about our Industry that are posted daily online?

Well I haven’t tasted any 3D printed food yet and I’m not sure I’m on board with that, but know that many of my colleagues are excited about the possibility. However, when it comes to fashion, I am proud to be working for a company that has been working with the designers who first brought this application of 3D printing to the public’s attention. In collaboration with Iris van Herpen, we have brought 3D Printed fashion to the Paris runways, have worked with designers for New York fashion week as well as bringing our own 3d Printed fashions shows to audiences all over the world – and of course, together with Studio XO, we saw Lady Gaga wearing a 3D printed dress for the first time with her most recent album launch.

 

Are there any new applications for Rapid Prototyping you feel will emerge over the next few years?

As 3D printing continues to grow, I think more and more industries will see the benefit to applying it to their processes. For example, we have already seen the realization of 3D printed insoles, surgical guides, mass customization and the production of hearing aids and as the machines, materials and software continue to improve, even more applications will start to emerge.

 

If you could make a prototype of anything with no care given to time or cost, what would you create?

Well I love to boat so I would love to create a customized 3D printed bimini for my boat or even to print some accessories or replacement parts for it. But I am also fascinated by all the 3D printing in the medical field, which Materialise also plays a large part in. All these advances make me optimistic that if I were ever to need a knee replacement or brain surgery or anything else, 3D printing would play a pivotal role in it.

 

What trends should AM business owners be looking to follow over the next century in your opinion?

I think more people will look to 3D printing for mass customization. There are definitely industries where this makes a lot of sense and also some where it doesn’t. So finding the right niche is key. Also applying 3D printing to more person specific parts or goods – like a customized steering wheel to your hands or headphones that are made for your head like a company in New York is doing.

 

Where do you think 3D Printing will be 50 years from now? (This is just a fun guess, futuristic question)

Wow! That seems so far off. So many things could be possible by then – organs and tissue – more cars and houses. Also I see it being more integrated and utilized with traditional manufacturing.
