WASHINGTON, July 30 (Reuters) - The United States is suspending a “de minimis” exemption that allowed low-value commercial shipments to be shipped to the United States without facing tariffs, the White House said on Wednesday.
Under an executive order signed by President Donald Trump, packages valued at or under $800 sent to the U.S. outside of the international postal network will now face “all applicable duties” starting on August 29, the White House said.
Fair, ya even around 10 mil is probably pretty tough with a reasonable cost cnc. I imagine with laser ablation, you’ll probably run into similar issues, you still have to physically move and point the laser, mirrors, or your target base.
I’ve got a little bit of a background in optics and sensors, but diy photolithography still seems pretty challenging, would be interested in following your work if you go down that route.
Computer-controlled laster etching/cutting is a thing - ideally we have as few manual steps as possible.
Ya ya, but same with cnc, you have things like backlash and physical control challenges.
