MRRF: Roundtable And Roundup

March 20, 2014 by Brian Benchoff 9 Comments

Last weekend Hackaday made a trip out to the Midwest RepRap Festival in Goshen, Indiana. We met a ton of interesting people, saw a lot of cool stuff, and managed to avoid the Amish horse and buggies plying the roads around Goshen.

We’ve already posted a few things from MRRF, including [Jordan Miller] and co.’s adventures in bioprinting, a very cool printable object repo that’s backed by a nonprofit LLC, some stuff from Lulzbot that included a new extruder, stretchy filament, and news of a 3D scanner that’s in development, ARM-based CNC controllers including the Smoothieboard and capes for the Beaglebone, 3D printed resin molds, the newest project from [Nicholas Seward], creator or the RepRap Wally, Simpson, and Lisa, and 3D printed waffles. It really was an amazing event and also the largest DIY 3D printer convention on the planet. How this happened in Goshen, Indiana is anyone’s guess, but we’d like to give a shout out to SeeMeCNC for organizing this event.

With so many famous RepRappers in one place, it only made sense to put together a round table discussion on the state of RepRap, 3D printers, and microfabrication. We have a 40-minute long video of that, which you can check out after the break.

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

February 26, 2014 by Rich Bremer 31 Comments

Last week we started to Make a Thing in Solidworks. We got as far as sketching and extruding the base. This week we’ll make the back portion. We’ll use some of the same techniques in Part I and a few new features such as 3D filleting and the Hole Wizard.

As you know, this is not the first ‘Making a Thing’ tutorial. In case you missed them, the softwares previously covered in the 3D Printering series are:

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

February 19, 2014 by Rich Bremer 44 Comments

Brian has graciously allowed me to hop on the 3D Printering bandwagon to write a brief intro to the wonderful world of Solidworks. We’ll be making the same ‘thing’ as done in the previous ‘Making a Thing’ tutorials:

Admittedly, most Hackaday readers probably don’t have Solidworks as it is a very expensive program. The main reason we are posting this tutorial is so that you can understand the work flow and compare it to some of the free/open packages out there.

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

February 15, 2014 by Brian Benchoff 35 Comments

It’s time once again for another installment of a Making A Thing tutorial, where I design the same part, over and over again, in multiple 3D design software packages.

Last week we took a look at FreeCAD, a free, open source parametric modeller. It’s an amazingly powerful tool, and not it’s finally time to complete our model of a strange object ripped from the pages of an 80-year-old drafting textbook.

Here’s some links to previous Making A Thing tutorials, doe:

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

February 5, 2014 by Brian Benchoff 33 Comments

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

January 15, 2014 by Brian Benchoff 22 Comments

printering

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.
