The Fourneau Bread Oven Has Been Backed!

Congratulations to Strand Design, in Chicago, and their Fourneau Bread Oven for getting fully backed on Kickstarter! Hoosier Pattern had the pleasure of helping make the protoype molds for the Forneau Bread Oven with our 3D sand printers. With 15 days left in it's Kickstarter campaign, The Fourneau Oven hit its goal of $90,000. Our president and owner, Keith Gerber is a backer of this project and we know he can't wait to start using it and bringing in fresh bread for his employees... right, Keith? 


Again, congratulations to Strand Design and their Fourneau Bread Oven! It was a pleasure being a part of this project.

Paul McCartney is in the Building

Well.. sort of.


On Tuesday March 17th, an article was tweeted from Paul McCartney's twitter account with a link to an article about Paul's new music video, "Hope for the Future". The article went on to say that since Paul got scanned in 3D, they made a downloadable file that enables anyone to turn Paul into a 3D printable figurine as long as you have a 3D printer. Our Social Media Coordinator happens to be a Beatles fan and convinced her supervisor to try and print Paul. Less than 24 hours later, we pulled Paul out of our 3-D sand printer! Paul stands 7 and a half inches tall and will now be hanging out in the offices of Hoosier Pattern.

Leading the Way at Industry Shows

Hoosier Pattern is excited to be participating in the 2015 AMUG Conference, 2015 AFS Casting Congress and RAPID 2015.

AMUG Conference

Running April 19th-23rd, the 27th Annual Additive Manufacturing Users Group (AMUG) Conference will be held at the Hyatt Regency Jacksonville Riverfront in Jacksonville, Florida.  Hoosier Pattern’s Steve Murray will be leading and moderating the casting seminar track at the AMUG Conference for the second consecutive year.  In addition Steve will also be presenting on the topic of “3-D Sand Printing For Your Metal Casting Needs” and demonstrating the casting processes by melting metal in a microwave oven and letting the attendees cast metal objects into a sand mold or a ceramic mold to make their very own souvenir.

Metalcasting Conference

The 119th Metalcasting Congress will be held on April 21-23 at the Greater Columbus Convention Center in Columbus, Ohio.  Hoosier Pattern’s own Dave Rittmeyer will be presenting at this year’s Casting Congress with his presentation on rapid prototyping entitled, “How Fast is Fast and Why Do I Need Tooling”.  Dave will also be leading a panel during the workshop entitled, “Printing Your Future in 3D”.


RAPID 2015 will be held on May 19th at the Long Beach Convention Center in Long Beach, California. Dave Rittmeyer and Steve Murray will both be leading workshops at this event titled, “Designing Printed Sand Molds and Cores That Can be Cleaned and Handled” and “How to Use 3-D Printed Sand in Short Run Production and Prototype Castings”.

Visit the links below for more information on the upcoming AMUG, Casting Congress, and RAPID shows.  We are excited to have the honor to participate in these shows, and we hope to see you there!

Rapid Prototyping…”How Fast is Fast and Why do I Need Tooling”
Dave Rittmeyer, Hoosier Pattern Inc., Decatur, IN

You need prototype or low volume production castings? Do you need tooling to make those castings?  There are options available to produce those castings that are time saving and cost saving when a few factors are taken into account.  These new options may allow you to bypass tooling, have a shorter lead time and complete the project under budget.  Are you exploring these options or are you using the same methods that have always been in place at your organization?  We will review the four main factors that should be consider before you build tooling to produce your prototype or low volume casting.

To register for this workshop, go to:

“Printing Your Future in 3D”

Our industry is being transformed by the technology which enables printing of sand cores and molds, wax patterns and tooling directly from 3D CAD files. The technology is currently being used in many applications including prototypes, reproduction of antique automotive parts and other complex and lower volume production components.  During this workshop speakers will present the key aspects of the technology, latest research and advancements, how the technology can promote and enhance design freedom and product improvement. The workshop will be highlighted by presentations and a panel discussion by several foundries on how they are using the technology to expand markets, reduce lead time and improve cost.  At the end of the workshop from 4:30-5:00 discussion will be held to help form the first AFS ad-hoc committee on Additive Manufacturing.

Designing Printed Sand Molds and Cores That Can Be Cleaned and Handled
Dave W. Rittmeyer, Customer Care & A.M. Manager, Hoosier Pattern Inc.

Just about any CAD person can design a mold or core, but their design may or may not be able to have all of the unbound sand completely removed. They also have to be designed so that they can be safely handled. Some designs can make it impossible to remove all unbound sand. But there are some practices that can be followed to help increase the chances for successful removal of the unbound sand. There are many ways to handle printed sand safely. I will review some of the options that we have tested and used successfully.

How to Use 3-D Printed Sand in Short Run Production and Prototype Castings
Steve R. Murray, Sales Rep and Additive Manufacturing Consultant, Hoosier Pattern

What foundry components can be 3-D printed in sand – Molds Cores. Why use 3-D printed sand to make foundry molds and/or cores. No need for traditional foundry tooling. It’s a timing issue and eliminated cost of the tooling. No draft required thus reducing CAD design time. More iterations done faster. No penalty for complex designs. Core assembly is eliminated. How to integrate riser sleeves both insulating and exothermic in to your 3-D printed sand mold. Placing filters in your printed sand mold. Printed sand cores. Solid, shell or a hybrid. What each can bring to your design and your casting. Using ceramic cores in a sand mold. Designing your printed sand mold for safe handling.

Introducing the Employee Spotlight

Happy Wednesday! 


Hoosier Pattern has decided to draw attention to the people behind the scenes in the building. A functioning business would not be functioning if it did not have employees. We know we hire the best of the best and want to share some of what makes our employees who they are. That being said, Hoosier Pattern will be doing an employee spotlight weekly, and for our first spotlight we are going to shine the light on our newest employee, Alyssa Corral. Alyssa recently joined the Hoosier Pattern team as the social media coordinator.
