3D Printering: Making A Thing In FreeCAD, Part I

printering

I’ve been writing these tutorials on making an object in popular 3D modeling programs for a while now, and each week I’ve put out a call for what software I should do next. There is one constant in all those comment threads: FreeCAD. I don’t know if these suggestions reflect the popularity or difficulty of FreeCAD nevermind, it’s totally the difficulty.

FreeCAD is an amazing tool that, if used correctly, can be used to make just about any part, and do it in a manufacturing context. If you need a bauble that’s three times the size of the original, FreeCAD’s parametric modeling makes it easy to scale it up. If you’re designing a thumbscrew and want the head larger while keeping the threads the same, FreeCAD is for you. Basically, you can think of this as a graphical extension of the Thingiverse Customizer. Very powerful, very cool, and unlike a lot of CAD packages out there, free.

Our in-house, overpaid SEO expert (he’s really just a monkey someone trained to use a bullwhip) demands I link to the previous ‘Making a Thing’ tutorials:

The tutorial for FreeCAD continues below.

3D Printering: Making A Thing In Autodesk 123D

In the continuing battle against 3D printers used exclusively for fabricating plastic octopodes and useless trinkets, here’s yet another installment of a Making A Thing tutorial. If you’ve ever wanted to make one single object in multiple 3D design softwares, this is for you.

Previously, we’ve built a ‘thing’ in a few different 3D modeling programs, including:

3D Printering: Making A Thing With SketchUp

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.

3D Printering: Making A Thing With Blender, Part II

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.

3D Printering: Making A Thing In Blender, Part I

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.

3D Printering: Making A Thing In AutoCAD, Part II

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.

3D Printering: Making A Thing With AutoCAD, Part I

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.
