Imagine for a second it’s the mid-1980s and you’re looking in to desktop publishing setups. Those new LaserJets and LaserWriters are pretty cool, but imagine the desktop publishing world if you couldn’t create your own documents. Yes, it seems absurd to have a printing press that won’t create unique documents.
Now flash forward 30 years to the world of desktop manufacturing and rapid prototyping. There are dozens of repositories for 3D printable objects, but making something of your own design is apparently a dark art and arcane knowledge to everyone buying 3D printers for plastic octopodes and bottle openers.
This week, by popular demand, we’re going to be making a ‘thing’ in SketchUp Make. It’s free, easy, and surprisingly versatile despite its limited tool set. Common sense and Google algorithms dictate I link to previous tutorials in this series below:
And now on with the show. You’re gonna want to click the ‘read more’ link.

So you have a 3D printer and need to print something of your own design. That’s a problem if you don’t know how to create and edit 3D objects. In this post, we’re continuing our previous misadventures with Blender by making a ‘thing’ torn from a very old book on drafting.
Previously, we’ve made the same part in other 3D design packages. Here’s some links to those other ‘Making a Thing’ posts:
We’ve already done half the work to make a ‘thing’ in Blender, so now it’s time to finish the job. Check out the rest of the tutorial below.

In case you weren’t aware, having a 3D printer is nothing like owning a real-life Star Trek replicator. For one, replicators are usually found on Federation starships and not hype trains. Secondly, the details of how replicated objects are designed in the 24th century is an issue completely left unexplored by TNG, and DS9, and only a minor plot point in a few Voyager episodes. Of the most likely possibilities, though, it appears replicated objects are either initially created by ‘scanning’ them with a teleporter, or commanding the ship’s computer to conjure something out of the hologrid.
No, with your own 3D printer, if you want a unique object you actually have to design it yourself. Without a holodeck. Using your hands to move a mouse and keyboard. Savages.
This series of ‘Making a Thing’ tutorials aims to fix that. With this post, we’re taking a look at Blender, an amazing 3D modeling and animation package.
Because we still haven’t figured out the best way to combine multiple blog posts together as a single resource − we’re working on that, though − here’s the links to the previous “Making a Thing” posts:
This list is sure to grow thanks to your suggestions on what 3D modeling software to feature, but for now let’s make a thing in Blender.

It’s time once again for another part in 3D Printering’s series of Making A Thing. Last week was a short tutorial on the beginnings of making a thing in AutoCAD. This is an extremely complex software package, and in a desire to make things short and sweet, I broke this AutoCAD tutorial into two parts.
Since we already covered the 2D design portion of AutoCAD, part II of this tutorial is going to turn our 2D part into a three-dimensional object. Check out the rest of the tutorial below.

Octopodes and useless plastic baubles begone. It’s time yet again for another installment of learning how to make a thing with 3D design tools. This week, we’re making something with AutoCAD. It’s an amazing piece of software that costs $4000 per seat. Hilariously expensive for any home tinkerer, but if you go to a university with an engineering program, there’s a computer lab with machines running AutoCAD somewhere on campus.
Last week we took a look at making something with OpenSCAD. AutoCAD is much, much different. Where OpenSCAD is sorta, kinda like programming, AutoCAD is just a digital version of t-squares, triangles, straight edges, and people getting uppity when you don’t call their drawing device a ‘lead holder’.
I’ve broken this tutorial down into two parts: right now you’re reading the tutorial on drawing 2D objects in AutoCAD. This weekend I’ll publish the transformation of 2D objects into a 3D printable part. Read on for how to create a 2D object in AutoCAD.

A lot of the ‘prosumer’ – for as much as I hate that word – 3D printers out there like the Makerbot Replicator and countless other Kickstarter projects only officially support PLA filament. This has a few advantages from a product development standpoint, namely not necessitating the use of a heated build plate. There are other reasons for not supporting ABS and other filaments, as one of the Kickstarter updates for the Buccaneer printer elucidates (update available to backers only, here’s a mirror from somebody on reddit).
The main crux of the Buccaneer team’s decision not to support ABS is as follows:
We spoke to our legal counsel about it and they told us that if we officially support a certain “material” type then our printer has to go through massive certification to prove that it is totally safe to use or we will/can get sued badly.
Despite the Buccaneer team’s best efforts, we’re sure, their lawyers were actually able to find some studies that showed ABS could affect a person’s health. The issue isn’t with the ABS itself – LEGO are made of ABS and kids chew on blocks all the time. The issue comes from the decomposition of ABS when it is heated.

Gather ’round, children and I’ll tell you a tale of how everyone from the ages of 16 to 40 has played Oregon Trail.
Back when Apple was just starting out, [The Steves] thought it would be a good idea to get the Apple II into the hands of schoolchildren across the United States. They did this with educational pricing, getting Apple IIs into newly created ‘computer labs’ in schools across the country. These new computers – from my experience, anyway – were used as a replacement for the old Selectric typewriters, and on rare occasions a machine that played the MECC classics like Oregon Trail.
Fortunately, a few students were bright enough and had teachers who were brave enough to allow BASIC programming, PEEKs and POKEs. This was the start of a computer revolution, a time when grade schoolers would learn a computer wasn’t just a glorified word processor or dysentery machine, but something that would do what you told it to do. For those kids, and I’m sure a few of them are reading this, it was a life changing experience.
Now it appears we’re in the midst of a new revolution. If this horribly named column isn’t enough of a clue, I’m talking about 3D printing. Yesterday, Makerbot announced they were going to fill in for Apple in this physical revolution by trying to get a Makerbot into every school in the country.
