Every successful venture starts with accurate and detailed laser cut design files when it comes to laser cutting projects of all kinds.
In traditional and older cutting methods, a hand-drawn sketch or blueprint would suffice for simple cutting instructions. However, today, when it comes to harnessing the power of precise laser cutting machines, you need laser cut design CAD files to ensure that every cut, hole, engraving, or marking is a 100% match to the original part or product specifications.
Therefore, when it comes to how to design laser cut files, manufacturing companies have plenty of options.
Your laser cutting resource can help you design, prepare, and test these CAD files for laser cutting (or more specifically DXF files for laser cutting). However, it’s helpful to understand how to create these designs and turn laser cut files into realized results.
Understanding the Basics of Laser Cutting
Even though laser cutting technology has existed since the 1960s, the process from initial design to finished laser-cut parts or products has advanced exponentially, especially in the past decade or two.
Today, the laser cutting process starts with computer-aided design (CAD) software. This is where the exact specifications of the part or product to be cut are created in highly defined detail.
Laser cutters provide speed, accuracy, and most importantly, precision. In fact, the best laser cutting machines – like the TruLaser series – have the capability to produce detailed cuts as small as .02 inches in most metal materials. As such, you need software to account for these minute specifications and ensure the overall design is as accurate as possible.
Creating Perfect Design Files for Laser Cutting
Once the design is final, you can send it to the laser cutting services provider, computer numerical control (CNC) takes the reins. Again, the best laser cutting machines rely on advanced technology, specifically computer numerical control, to ensure no deviation from the original specifications. This automation also ensures that every part or product is correct, even in production runs of 1,000 units or more.
The CNC laser cutting machine effectively follows the instructions for every part or product, directing the laser head and laser beam onto the sheet metal. Moreover, the process is repeated as often as needed until the project is complete.
This reliance on technology from start to finish minimizes imperfections, interruptions, or issues, and ensures that every laser cut project exceeds expectations in terms of speed and accuracy.
Accepted Files Format for Laser Cutting Machines
There are different types of design files that can be used to share laser cutting instructions. However, the most file formats common are as follows.
DXF Files
DXF stands for Drawing Exchange Format or Drawing Interchange Format. Furthermore, DXF files are a vector format that is used to store and share 2D and 3D designs between different CAD software platforms.
In laser cutting, DXF files are the preferred file format. In addition, there are ample options when it comes to software that can help create these files, including free and easy-to-use programs like Inkscape®.
When in doubt, always opt for a DXF file for laser cutting. DXF files are the preferred type of instructions at most top laser cutting service providers, including Steelway Laser Cutting.
SVG Files
SVG stands for Scalable Vector Graphics, and SVGs are a vector file format that uses mathematical formulas to store images. Many designers work with SVG files because they are easy to resize, and can support animation and other web-friendly attributes.
They are usually smaller than other image files like JPEGs or PNGs. If you work with SVGs, you can easily convert these file types into DXF files as needed. This all depends on your laser cutting service provider’s specifications.
Other File Types for Laser Cutting Designs
There may be other file types that can be converted easily to DXF files for laser cutting. These file types include EPS or AI files created with popular software like Adobe Illustrator. When in doubt, it’s best to talk to your laser cutting services provider for their recommendations and guidance.
An expert in the field like Steelway Laser Cutting will work with you every step of the way to ensure all laser cutting specification requirements are met.
Tips for Preparing, Creating, and Finalizing Your Laser Cut Design Files
Before you send your DXF files for laser cutting projects, be sure to double-check the following.
Convert All Text to Outlines
If your vector design has text boxes instead of outlined shapes, the CNC laser cutter may not be able to process the cut accurately.
Avoid Intersections or Common Lines
Triple- check your design to ensure that no two parts touch or share a line. It is also important to ensure that no lines intersect or overlap with one another so that the CNC laser cutter does not misinterpret these intersections.
Avoid Empty Objects or Disconnections
Ensure that your shape and specifications feature no open contours. This means the shape must connect completely around. This can lead to gaps in the cutting process, as the laser will follow the shape exactly and will stop if the outline stops.
Ensure Your Design is Correctly Scaled
It is helpful to make sure that the design matches the exact size needed for cutting and verify all dimensions before starting the cutting process.
Remove Excess Information
To save time and effort, remove any excess instructions, dimensions, notes, extra borders, or unused objects from your file. The DXF file for laser cutting should only include the actual cut path or other required instructions that the laser cutting machine will follow.
