The Challenge
Welding fixtures are assembled from inaccurate modular fixturing or expensively machined, forcing you to choose between quality or cost.

The Solution
Markforged 3D printed welding fixtures are heat-resistant enough to operate near welding surfaces while being conformal and accurate.

The Impact
Printing welding fixtures allows you to achieve the weld quality of CNC fixtures for the cost and complexity of low-fidelity solutions.

The only thing more critical to welding success than good fixturing is a good welder. For welds more complex than joining planar surfaces, welding fixtures help welders ensure that they’re joining the right things together in the right locations. Conventional welding fixtures tend to fall into three categories—expensive machined components, uncustomized modular fixturing, and hacked-together solutions. Each of these has its own downside: machined fixtures are effective but expensive to produce, modular fixtures are cheap but difficult to assemble, and hacked-together solutions produce poor welds far more often than successful ones.

With 3D printing, you can marry the quality and ease-of-use of machined fixtures with the cost and manufacturing simplicity of modular fixtures. Markforged parts are heat-resistant enough to hold the vast majority of welded parts, and can easily integrate with metal hardware to provide extra heat buffers if necessary. Complexity is free on 3D printed welding fixtures—as a result, you can design parts that conformally and securely hold complex assemblies for welding. If your design changes, you can quickly and cheaply print an updated fixture.

The Challenge

Inspection fixtures are traditionally made from either difficult-to-assemble modular fixture systems or expensive custom machined fixtures.

The Solution

3D printed inspection fixtures hold parts precisely and securely for all types of part inspection.

The Impact

Specialized fixtures drastically cut down the time required to design, test, and implement fixture designs for a wide variety of products.

Inspection fixtures fall into two main categories—CMM fixtures and go/no-go gauges. Each fulfills a critical part of the manufacturing process: ensuring that fabricated parts hit the tolerances of the designs they were fabricated from. Conventionally, these fixtures are either constructed with modular kits or custom CNC machined. Modular fixturing is cheap, but difficult to assemble and not quickly swappable. CNC fixturing works well once it’s fabricated, but the complex geometry of many inspected end parts (especially CNC machined or cast-and-machined) adds significant cost to the fixture manufacturing process.

3D Printed inspection fixtures are precise and conformal. Whether it’s a CMM fixture or a go/no-go gauge, the geometric complexity that 3D printing naturally affords allows you to quickly design and optimize fixtures for your part. Markforged’s continuous fiber reinforcement makes these fixtures long lasting and strong enough to fixture heavy parts for inspection. Printed fixtures are easy to set up, take down, and store, meaning that you can have custom fixtures readily available for all parts that you need to inspect.
