Other Operations

We don't cut wood or plastic, and we don't support raster engraving operations on metal, but our friends at Pololu can help you out!

Our laser-cut parts are offered "as cut" - we do not currently offer bending, grinding, tumbling, sanding, or any kind of painting, anodizing, or powder-coating operations on finished parts.  Our fiber laser produces a remarkably clean, dross-free finish, especially on materials 3/16" thick or less.  But your finished parts may require some minor post-operations to make them product-ready.  We take care to prevent scratches on the surface of the material, but there may be minor scratching on the surfaces from general movement and placement on the machine for cutting.

Carbon steel and stainless cuts leave a clean bottom finish, with a minimal amount of dross and little to no burr.  Very small internal cutouts can exhibit some "pierce splash" on the part, where a small amount of material is ejected from the pierce hole during the cut, affecting the surface finish in a small area around the pierce.  This only affects small areas, where the machine must pierce close to the cut edge.  Bottoms of parts may also have a minor amount of "splash up" from the deck, where the laser hits the still honeycomb patterned deck and splashes a small amount of steel onto the part being cut.  Splash up is easily removed.

More details about finish quality on laser-cut parts of different material types can be found below:

Aluminum leaves a minor burr on thicker materials, which is easily removed by hand or a sanding operation (see below).

Fiber laser aluminum cut quality - 0.1" thick

Fiber laser aluminum cut quality - 0.25" thick

Cutting Tolerances

Our fiber laser has a head positioning tolerance of +/- 0.005" across the entire 5' x 10' deck.  Kerf compensation is performed automatically by the machine, so if you ordered a large part in thin material, you could expect the part width and height to be accurate to within roughly 0.01" across a full 10' span, worst-case.

Over a smaller work area, positioning tolerance is closer to +/- 0.002".  You can expect the size of small holes to be within +/- 0.001".

If your laser-cut holes are designed to be threaded, or to be used in a press fit application, it may be necessary to undersize the holes in your drawing and drill or ream the resulting hole to obtain a good edge finish and consistent size from top to bottom of your laser-cut part.

Thicker materials ( > 1/8" thick) exhibit increased hole size on the bottom of the part, as the beam and assist gases expand through the material.  The effect is minimal for thin materials, but very pronounced in 3/4" thick steel. See our Edge Cutting Tolerances guide for more details.
