APTUS Building

Located near downtown Maryville, Tennessee, our facility was designed and renovated in 2012 specifically to suit our business. Originally constructed in the 1940’s, the standalone building includes a 2,200 square foot office and conference room area with a prototyping and measurement lab, as well as 1,500 square foot shop for assembly and product testing. An adjoining 3,000 square foot covered secure storage area is available for large equipment or first-article staging during our client’s production start-up phase.

All mechanical design is completed using SolidWorks 3D solid modeling software. Any version from 2007 through current can be used as needed to suit customer requirements for backward-compatibility. Basic Finite Element Analysis is completed using Cosmos-based FEA software. We can work from most legacy CAD formats including 2D data.

SolidWorks Industrial Design & The Foundry’s Modo are utilized to design complex freeform shapes as well as digitizing 3D scans. We are also able to produce photo-realistic marketing and communications materials for our customers.

Prototype measurement, officedimensional checks, and reverse engineering is completed in-house on our granite measuring surface. High quality measurement devices, including a 6-axis Romer Articulated Arm Coordinate Measuring Machine (CMM), allow the measurement of complex geometry and irregular surfaces. Each measurement is made using equipment calibrated to NIST-traceable length standards as needed. For more organic shapes our laser-scanner may be used to bring existing geometry into the CAD environment for reference during the design process.

Our in-house Additive & Subtractive Rapid Prototyping machines allow for extremely quick prototype iterations, with the ability to use full strength representative material when needed. We also maintain close relationships with local and national prototype and manufacturing shops. These in-house and partner resources give us the vast array of prototyping abilities that moves projects through the testing phase quickly and effectively.

Real-world engineering, with real-world budgets.

Many of the APTUS DesignWorks staff are involved in local motorsports communities and racing clubs. Building vehicles and competing in automotive competitions is yet another way that our designers utilize their skills to solve real world problems. APTUS is proud to sponsor cars in both East Tennessee Region SCCA Solo competition and the Knoxvegas Lowballers in the 24 Hours of Lemons racing series. The 24 Hours of Lemons is a budget racing league and specifically rewards drivers and car builders who find creative and inexpensive solutions to the toughest of problems.

Getting there faster means better customer service.

APTUS is passionate about General Aviation. Some members of the APTUS team have earned their private pilot’s license to enjoy the flexibility, speed, and fun that small airplane travel brings to personal and business life. APTUS selectively uses general aviation to allow more face-to-face meeting opportunities with less total time invested. By flying to a client location instead of driving or flying commercial we cut hours off of the work day, allowing us to provide the personal service our clients deserve while still getting home to our families. This supports the healthy work-life balance required to make our business sustainable long-term.The time saved by traveling more efficiently more than offsets the higher price of air travel compared to driving. To manage overhead costs, we participate in a local cooperative aircraft ownership organization. The business directly supports all pilot training costs through our education reimbursement program.

APTUS DesignWorks Inc. is committed to being a responsible corporate citizen and proactively supporting the local community.

APTUS is a proud sponsor of the local Blount County Robotics Team as well as the national FIRST Robotics Competition.

Tennessee Inventcon

APTUS was asked to present at the 2018 TNInventcon conference for innovation development.  The primary goals of this convention are to educate inventors and entrepreneurs about the fundamentals of bringing a product to fruition as well as putting them in contact with good local resources.

Science Fairs

APTUS Engineers regularly participate as judges in local and regional science fairs. The photo below shows our entry in the 2009 Carpenter’s Middle School balsawood bridge-building competition. Our involvement served to challenge and inspire the students as they designed their own bridges. The video at the bottom of this page shows the 14.9g bridge failing at just over 100lbs load.
