Laser cutting 3D forms: 123D Make tutorial

Slicing up a T-Rex for laser cutting that roars

The software options available to digital makers just keeps getting better, and one of our recent favourites would have to be Autodesk’s 123D Make.

Why do we like 123D Make so much? Simply put, it just works and really is as easy as 1, 2… 3. The freely available software takes a 3D model and slices it up, then exports the data for laser cutting.

As you’ll see in the following tutorial, there are several very handy (and quite powerful) capabilities built in to 123D Make that help ensure your final result comes together just right.   (more…)

What to do with your first laser cut design

Four scenarios and next step options for first-time makers

You’ve created a design and uploaded it to Ponoko, placed and order, and now you have your first piece of laser cut delight. So now what?

It all depends on what stage of the process you’re in. We’ve come up with four scenarios to keep things moving. See which one best describes you.

Scenario #1

You: My design is not quite right – it didn’t work out!

Ponoko: Don’t let this get you down. The first try pretty much never turns out perfect for anyone. Making something is a process, and you’re in the prototyping phase. Most of our customers have to make 5-10 prototypes to get their design just right. Don’t forget that we will do whatever it takes to help you get there!

What to do next:

• If you’re not sure why your design didn’t work out or if you think we messed something up, get in touch: service-at-ponoko-dot-com
• If you know what needs to be changed, revise your design and try again. To speed up the prototyping process, we recommend putting multiple versions of your design on a single sheet of material and see which one works best.

Using free design software to customize a design file

For the second instalment of Ponoko’s back-to-basics tutorials, we walk through the process of customizing a design file using freely available design software. The recommended software is called Inkscape, an open-source vector drawing program that offers powerful features in an easy-to-learn format.

Making use of the same free design file introduced in part 1 of the Laser Cutting Tutorial series, this time we walk through the process of adding your own text to the laser cut coaster.

Follow through as the process is explained from downloading Inkscape through to preparing the custom file for uploading to your Personal Factory.

In just under six minutes, you will know how to:

• Download Inkscape (available for Mac or PC)
• Open a design file in Inkscape
• Customize the design file with your own text
• Prepare the file for laser cutting

Now we’re just about ready to generate custom designs from scratch using Inkscape, so stay tuned for our Laser Cutting Tutorial Part 3.

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…)

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!

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…)
