How CNC Machine Shops Can Use 3D Printing to Save Time and Money

CNC machine shops are known for making precise, quality parts. But even the best shops can benefit from new tools. One tool that’s becoming more popular in the machining world is 3D printing.

At 3D Printing Squared, we work with machine shops that want to speed up their workflow, lower costs, and take on more complex jobs by using 3D printing alongside traditional machining.

Why 3D Printing Works Well with CNC Machining

3D printing isn’t here to replace CNC—it’s here to help it. While CNC is great for cutting strong materials like aluminum and steel, 3D printing is perfect for things like:

• Prototypes – Print a plastic version of the part before cutting metal. It helps check fit and design.

• Custom Fixtures – Print jigs, soft jaws, and holders for one-time jobs or fast setups.

• Customer Samples – Show a printed version of the part to the customer before you machine the real one.

This saves time, reduces mistakes, and helps make better decisions before using expensive materials.

Tough Materials for Shop Use

Modern 3D printing materials are stronger than ever. Options like PETG, carbon fiber nylon, and reinforced PLA are being used in real shop environments. They’re great for:

• Holding tools

• Checking part fit

• Temporary replacements

• Light-use parts and tools

Some shops even print soft jaws or custom vise inserts that hold odd-shaped parts for milling.
