LiDAR for the DIY and Hobbyist UAV Enthusiasts

Posted April 25, 2017 12:00 AM by Engineering360 eNewsletter

There are now LiDAR options that cost in the hundreds of dollars — rather than in the thousands — that are good for do-it-yourselfers and hobbyists. Previously, high costs limited the appeal of the technology for individual use.

Laser Engraving Tips from the Experts

Pathfinder Tags: epilog laser laser engraving

Need recommendations for solid hardwood engraving? Nervous about etching glass? Looking for inexpensive substrates to play around with?

Experts from Epilog Laser have answered some of the most frequently asked questions found in the Epilog Laser Fan group.

Engraving on plywood or balsa

This material is cut with a laser more than it’s engraved. For engraving, start with the recommended wood engraving settings in our manual. Plywood can be tricky and inconsistent in terms of cutting, due to the various layers of glue found within it. Balsa seems to cut very nicely and many of our customers use this medium to build various types of models.

Cool projects you can create with scrap pieces from other projects

Scrap materials are great not only for creating new projects, but using as practice pieces for more challenging engravings, such as photographs. We’ve seen customers make all kinds of things from scrap, such as small acrylic edge-lit signage, ornaments, name tags, and lots more!

Cardboard 3D bowling pins anyone?

Recommendations for solid hardwood engraving

Mask the wood.
Masking helps reduce residue from seeping into engraved areas and makes for easy clean up.
Use “bottom up” engraving. This is a feature in Epilog’s print driver that allows users to engrave from the bottom of the design up, instead of engraving from the top down. It also helps reduce smoke and debris being pulled into the engraving area as the laser head moves.

Once you nail down answers to your questions, you could create something like this wooden model:

Laser Etching Your Way into a New Wardrobe

Posted March 19, 2017 12:00 AM by Epilog Laser

Hobbyists aren’t the only group taking part in laser-engraving action. Even designers are incorporating the technology for fresh and unique clothing.

The Maker Movement made an appearance at last season’s MET Gala when some attendees showed up in laser-cut couture.

Check out Autodesk designer Amy Karle. She’s taking fashion to a new high-tech level where she scans her drawings into the computer and then scales them to fit the human body.

Why, you ask? Well, one benefit is that you’d never have to worry about a trip to the tailor again since your clothes would always be made-to-fit.

Ok, not everyone is a skilled designer. We get it. But even at-home laser-engravers and tinkerer can engrave fabrics with logos and designs to add a special touch. From cotton, to suede, to twill, to nylon, a laser system can cut them all. Anyone can take designs from almost any graphic design software and print it to the laser. In the print driver you'll select a speed and power for the material you are cutting.

Check out these laser-etched jeans:

How about these shirt appliques? The customized T-shirt possibilities are endless:
