Digital Development Program™

Whether you are not sure where to start, have an idea for a 3D printing application, or have experience launching additive manufacturing applications, let’s work together to make your next application successful.

The Digital Development Program (DDP) is Extol’s proven innovation process to develop high-value applications for 3D printing and transition them to production. Based on Human Centered Design, the DDP is a step-by-step development process that allows for agility and partnership that is required for bringing new innovations to life. 

Each manufacturing method (injection molding, extrusion, etc,) has specific requirements for design and manufacturing, and so does additive manufacturing. Additive manufacturing is a cutting-edge technology, and many applications are the first of their kind. This requires attention to the economic value proposition, systems thinking, and manufacturing scalability, which can only be done in partnership.

Here are the steps we take together as we walk through the DDP:

Discover – Understand context and systems and identify opportunities for 3D printing.

Define – Identify the economic value proposition and technical application requirements.

Develop – Design for additive manufacturing, prototype, and validate that the design meets the economic value proposition and application requirements.

Deliver – Prepare to scale and reduce the risk of a new manufacturing process by identifying critical quality characteristics and a plan to control them.

Chart with the discover, define, develop, deliver steps outlined

Let us help you make your next application successful.

Extol hosts assembly workshop at Additive Manufacturing UG Conference

Extol led a hands-on workshop at the annual AMUG conference this year. People learned how to use welding and assembly to find the best solution to meet their 3D printing application’s cost, performance, and lead time needs. Expand your knowledge through my conversation with Extol’s Kyle Harvey about AMUG and the welding and assembly workshop.

Top 6 Reasons Machine Builders are Switching to 3D Printing

Top 6 Reasons Machine Builders are Switching to 3D Printing

3D printing technology and materials have advanced rapidly, offering new possibilities and advantages for machine builders. Machine builders are replacing traditional CNC machining and urethane casting processes to use 3D printing for applications such as fixtures, EOAT, tricky custom details, and first shots of customer parts for debugging. Let’s explore some of the benefits of 3D printing for machine builders, focusing on design freedom, reducing lead time and cost, reducing detail count, replacing messy urethane casting, keeping debug timelines moving, and reducing weight.

Which Unlocks More 3D Printing Applications? – DfAM or Business Model Innovation

Which Unlocks More 3D Printing Applications? – DfAM or Business Model Innovation

Despite the promise of Additive Manufacturing (AM), many organizations have failed to capitalize on its potential. This is partly because AM presents a unique set of challenges, which can be difficult to overcome without extensive experience and expertise. As a result, many organizations have pursued applications that are not well-suited for AM, leading to late and expensive failures. In order to maximize the benefits of AM, organizations need to invest in and deliver successful applications. With the right approach, AM has the potential to change the world.
