Get to know your laser cutter better

DIY Kerf measuring tool refines your laser cutting precision

Although it isn’t critical on all laser cut projects, for anything with parts that fit or slot together, kerf is something that is worth paying attention to.

It may sound like a Jim Henson creation – but kerf is in fact a very real technical term. Kerf refers to the gap that is left by the cutting device – in our case, the laser beam in a laser cutter. It’s usually more of an issue when laser cutting in wood, but will also come into play when laser cutting acrylic and other materials.

Open source enthusiast Dave Chamberlin has come up with a nifty device that can be used to accurately measure the kerf of a laser cutter. The simple cutting pattern has been uploaded to Thingiverse, and includes instructions on how to measure your kerf etched right onto the device itself. Here is what it looks like:

Follow the source link below to download the file and try it out on your own laser cutter. You can also discover what else Dave is up to in his open source maker crusade over at Takeaway 3d Tech.

The Neo-Artist: Last chance to get involved

Time is ticking – Kickstarter campaign ends 4pm Friday EDT

When we recently discovered The Neo-Artist, it seemed like Lincoln Kamm was living the dream. He has developed an expertise in helping creative people find ways to produce and sell their work using the latest in digital manufacturing technologies, and now he wants to share it with you.

All of his knowledge (and a few extra practical perks) are condensed into the publication The Neo-Artist, which is the focus of a Kickstarter campaign that wraps up on Friday July 12 at 4pm EDT.

A nice snapshot of what The Neo-Artist is all about can be seen in the clip above, where Lincoln is interviewed by 3D Printer World. Watch the interview to discover more about the campaign, as well as cat-breading and other insights into Lincoln’s creative world that led him to share his expertise in The Neo-Artist.

If you need a little convincing to get involved in this campaign, one of the perks for backers is to receive discounted consultation time with Lincoln himself on your own projects. Imagine having personal, one-on-one time with an expert in making a success of making! Jump on board before it’s too late.

The Neo-Artist: a high-tech guide to making

One man’s mission to solve the economic downturn for creative people.

Lincoln Kamm spent 12 years in the animation industry before breaking out and producing his own works. He has since met with notable success with six-figure sales and is now helping others learn how they too can do the same.

In an upcoming publication The Neo-Artist, Lincoln expands on his college lecture series and consulting experience. The book is a treasure-trove of knowledge that aims to teach creative people about the latest in high-tech hardware and software for turning ideas into real physical objects.

Topics covered include 3D printing and laser cutting, designing custom electronics, clothing and more. Most importantly, The Neo-Artist will also show how to make other aspects of the available technologies work for you to help market and sell your work. It’s perfect for makers who are just starting out and will still have plenty to offer those who have been in business for years, guiding them to the next level and beyond.

So if you are a creative person who’s into technology, be sure to take part in The Neo-Artist Kickstarter campaign and make a pledge to secure yourself a copy of the book. It’s time to leave the rat race behind.

Multi-colour prints from a single extruder

Tutorial shows how to liven up your 3D prints

Are you finding the monochromatic output of your 3D printer a little drab? According to Andre Tiemann, coloured prints are easily achievable and he has written up a neat tutorial explaining how to achieve multiple hues… and you don’t even need to have the latest high-tech equipment.

With dual-head extruders becoming more and more commonplace, coloured prints may not seem so exceptional – but what sets Andre’s efforts apart is that he is producing multiple colours from a single extruder.

Referring to the prints as 2.5D (rather than full-blown 3D objects), he explains the process of colour swapping based on layer height to radically change the appearance of the printed object.

“…while this isn’t a breakthrough in 3D printing, it is a fun technique to liven up prints.”

Pibow: stacked laser-cut enclosure

A new way of building DIY electronics project boxes
Since the Raspberry Pi launched six months ago, a huge ecosystem of enclosure designs have sprouted up out of the creative commons community. The Pibow is a particularly innovative approach, consisting of a stack of laser-cut acrylic layers. It’ll be interesting to see how long it takes for this new technique to spread to through the community.

Tutorial: Gears & Joints with SketchUp and SketchyPhysics Part 2

Mechanical modelling with free software tools

Following on from last week’s introductory tutorial, here’s a bit more information on how to make mechanical models in SketchUp with SketchyPhysics. By the way, here’s a great resource if you want to learn more about mechanical linkages, gears, and all that good stuff (hat tip to Edgar Castelo for the link).

Tutorial: Gears & Joints with SketchUp and SketchyPhysics

Continuing my commitment to using free software even though it drives me up the wall sometimes

Following my recent obsession with drawing machines, I’m working on a new project with lots of gears and linkages. I figured it would be a good time to learn how to do mechanical modelling in SketchUp. Sketchy Physics is a plugin for Google SketchUp that allows you to simulate mechanical models. It is very capable but also very frustrating!

Figuring I’m not the first person to get frustrated on the way to creating meshing gears in SketchUp, I wrote this tutorial. I hope it will help some of you get up the steepest part of the learning curve.

Stay tuned for Part 2 coming soon.

Laser-Cut head with a secret compartment

Instructables tutorial: slice up your loved ones, hide your treasures inside.

Ever wondered what the CEO of Autodesk gets up to in his spare time? This guide from CarlBass on Instructables gives us a little insight into his private moments, as he walks us through a fantastic laser-cut project to create a secret hiding place for his son.

And what kid wouldn’t love a secret compartment that is inside their own head?!?

The process is all laid out on Instructables, and makes good use of a few handy apps from Autodesk.

Photographs are converted into a 3D model using 123D Catch, and then sliced up for laser cutting in 123D Make (after the addition of a generous cavity to hide all those treasures, of course!). Locations and alignments for dowels and magnets are also planned in, so that the completed form can snap closed to conceal the secret compartment.

As happens with all good Instructables guides, a lively conversation has followed in the Comments section of the post.
