Before you upload your files to SendCutSend, make sure to check for these common problems.
- Duplicate lines.
- Duplicate lines in your file will be rejected by our automated system since the laser cannot recognize or cut them. Be sure to go through the geometry in your file and make sure that there is only one of each cut line needed. This is especially important in 2D design software, which is another reason why we recommend you design your part using a CAD program like Fusion360 or Solidworks.
- Small geometry
- Geometry on laser cut parts should be at least 50% of the material thickness. Holes or interior geometry that are smaller than 50% the thickness of your material are unlikely to be cut accurately by the laser.
As an example, if your material is 0.100” thick, the smallest hole you could expect to cut would be 0.050” in diameter. A safe rule of thumb would be to keep all geometry greater than 1/2 material thickness, and no smaller than .015″.
- Shared Geometry
- Common-line or nested cutting (as shown in the drawing below) can lead to imprecise parts since it doesn’t account for our beam-width or kerf. Depending on the material, the gap between the parts will vary from .006″ to .012″ or more. You may want to design the inner part about .005″ smaller to allow for a slip-fit.
If you layout your parts as shown below on the right, we’ll be able to send you parts that will be much more precise, and they won’t have manufacturing imperfections like pierces and “lead-in” marks that we use to start the cut.
- Can I receive the “drop outs” or internal parts?
- Since our production process is mostly automated, we cannot send drop-through or scrap pieces with your order. Those sections will be destroyed or lost in our process. If there is a second piece you would like, it is best to submit it as a separate file to be cut.
- Nested Parts
- Please upload each part as an individual file. We will arrange your parts in a way that maximizes efficiency and reduces material waste. This process is known as “nesting”.
Designers are often tempted to “pre-nest” their design, thinking that it will speed up the production process. However, this is more likely to complicate the cutting and impede our process. If you want to cut multiple copies of a single object, don’t crowd your design, just upload a drawing with a single part and adjust the quantity in your cart.
