Vector Path Crosshatching

A quicker, cheaper alternative to raster fill engraving

Vector or Raster? It’s a question that has goes back to the earliest days of laser etching. Here is an interesting little exploration from the creative team over at Cuddleburrito that scores another point for the Vector camp.

Instead of using a raster fill for a job that required large graphic elements, they devised a way to create the same effect using vector paths.

This saves a huge amount of time, as the laser only needs to engrave the actual paths of the lines instead of sweeping across the entire area. There was an added bonus that the outcome has a more consistent appearance when applied on timber, because the tendency for grain variation to be emphasized (as when using raster etching) had been eliminated.

10 things to know before laser cutting with Ponoko

Useful information for both new users and laser cutting veterans

Are you a seasoned Ponoko maker? Or perhaps your imagination has been tingling and you are bursting to make your very first Ponoko product.

Either way, here is a top-10 list that we think will come in handy for those new to laser cutting, and it also contains useful information that will help more experienced Ponoko members keep things running smoothly.

Let us know what you would add!

1. How long it will take to make and ship your order.

We make all orders as quickly as we can, and how long that takes depends on the volume of orders we are processing at any one time. Due to the number of variables involved, we’ve written a separate post to help you work out the likely total time your order will take.
Read about our order timeframes.

2. If you are using Inkscape, you MUST use our design templates, or your design will be sized incorrectly.

We strongly recommend that everyone use our templates for laying out their laser cutting designs. If you are using Inkscape *it is 100% necessary*. The way that Inkscape works with measurements is different to other vector-based design software packages, and if you do not use our templates your parts will be made the wrong size. If you’ve already got an Inkscape design ready, we have created a guide to putting it on our templates.
Read how to place existing Inkscape designs onto our templates.

…so that’s the first two, and there are eight further important pointers to wrap your head around when you continue reading the full post.   (more…)

Laser cut Sphere-O-Bot

Teaching kids how to build their own mini making machines

Designed for a workshop series that introduces kids to building their own motor controllers, the Sphere-O-Bot is a simple 2 axis CNC machine that can draw on small spherical surfaces. Suggested target spheres include ping pong balls, eggs and even golf balls are apparently worth a try.

There is a thorough tutorial on Instructables that will take you through the thinking behind the laser cut wooden design, and show just how to put it all together. Files are included for the laser cut structure as well as specs for all the hardware required to get the Sphere-O-Bot up and running.

This fun project was uploaded by Juan, a Maker Corps intern at the Children’s Museum of Houston, who says:

“By building your Sphere-O-Bot using a laser cutter, you can achieve a clean look while also reducing the production time of your parts. This design also features an electronics bay for your wires, micro-controller and motor drivers.”

The basics of laser cutting with Ponoko

Helpful advice on how to get started with the Ponoko Personal Factory

For those who have always wanted to give Ponoko a go but are not sure where to start, this training video shows just how easy it is to produce your own laser cut designs.

In a little over ten minutes, Josh talks through the process of using Ponoko, and highlights a small project that makes a great starting point to help you feel your way with the Ponoko Personal Factory.

The material overview covers felt, cut and engraved bamboo, leather, 3d objects assembled from laser cut acrylic, and laser cut plywood. There is also advice on which materials are the best to get started with – and how to avoid common ‘beginner’ mistakes.

Then it gets to the good stuff – a neat little demo of how to actually make your very first product. The walkthrough explains how to use Inkscape to create a file that can be uploaded to Ponoko for laser cutting.

Starting with the Ponoko P1 template, Josh quickly whips up a collection of forms that use both laser cutting (for outlines) and laser etching (for surface details).

The upload process is then explained, with useful tips on how to check your files are correct and also how to order multiple copies of your design. Next comes material selection, which reveals some very useful information – how much it will cost! You’ll see that it’s really easy to switch to another material and see the price adjust accordingly in an instant.

The video wraps up with a few more handy design tips to be sure you start off on the right track.

Sound like fun? We think so. Watch the video, then dive right in!

Laser cut casing for DIY bluetooth speaker

Using a laser cutter to make a speaker casing with style

When Chilean designer Francisco Sahli needed to take his tunes on the road, he decided the best way would be to make his own stylish bluetooth speaker.

Many makers turn to laser cutting to build enclosures for their electronic projects. What sets this example apart is the departure from the usual boxy laser cut forms, with the result looking much more like a manufactured product.

Rather than the usual slotted laser cut corners, Francisco achieved a smooth radius and angled faces by laser cutting timber profiles and then laminating them together.

The final assembly was then carefully sanded by hand, before three coats of paint were applied. You can read all about the construction process, see the laser cutting paths and find out what’s inside to make the bluetooth speaker work its magic on Francisco’s website.

What is Laser Cutting?

Taking a step back to go through some laser cutter basics.

What is laser cutting, and why are we so excited about it?
As we’ll see in this brief overview, laser cutting is a relatively simple technology that makes it possible to cut or etch forms from sheet materials.

Laser cutters work in a similar way to other CNC (computer controlled) tools, however the cutting is done with a powerful beam of light instead of a sharp blade. To cut, the laser beam is focused to hit the material at a precise point, causing it to melt, burn or vaporize. Etching is achieved by focusing the laser on the surface of the material, where it will only burn or vaporize the topmost layer.

Laser Cutting is particularly useful because it works touch-free, meaning no mechanical forces or pressures are transferred to the material. This enables delicate cutting paths that can be repeated with a high level of precision, whether they are cut all the way through the material or etched as an impression onto the surface.   (more…)
