MakerBot Makes It Even Easer to Set Up Your Own 3D Printing Lab

MakerBot is now offering a new package for its popular 3D printers called the Starter Lab aimed at making set-up of a 3D printing lab for organizations and schools even easier. The package comes with everything you would need to make a 3D printing lab come to life including hardware, materials and accessories, software and support.

I needed a fork, so I drew one in Illustrator, extruded it in Maya, and printed it on a Makerbot.

Update: hmmm, stabbing hot foods makes the prongs bend because PLA is designed to melt and cool quickly.

Hey friends,
I’m really broke right now, and in desperate need of a little extra income. In light of that, i figured I’d offer some 3d printing services for sale.
For $15 I’ll send you a small 3D print
$25 for a medium to large 3d print
Shipping included if you live in the continental U.S.
You can go to thingiverse.com and choose pretty much any file that has a Creative Commons license, including these adorable Pokemon shown above.
I have the bulbasaur planter on my desk and it makes my life 100x better.

I can also custom design certain things for you! If you are trying to make a cosplay accessory, like belt buckles, badges, jewelry, and so on, hit me up and I may be able to design it for you!

I only have limited colors I can print in, but the prints can easily be custom painted.

Message me for details, or email me at sam@grrlab.com

Also, if you are uncomfortable sending money over PayPal, I have an etsy and I can set up a custom listing for you and have it all go through there.

If you’re not interested, maybe you can do me a favor and reblog this so I can get the word out. Thanks!!

3D Object Prototype - Headphone-Ready Phone Case

Scenario: The purpose of this assignment is to develop your ability to create 3D models for prototyping physical objects at medium fidelity.You have a free choice of what to model, but your design must use at least one of all of the following primitive operations:

  • Extrusion
  • Revolution
  • Boolean (adding or subtracting one object from another)

You may use any other capability you like in Rhino, but at least those 3.

Challenge: Create the model, convert it to a MakerBot STL file, and get it printed. Keep the size and resolution reasonable – there are 50 of you who have to get access to the machines, which are not the speediest of rendering devices. Remember, this is just a prototype.

The Design

Like most of my prototypes in this class, I decided to flip through my years of design notebooks to find something that could stand up to this challenge. The goal was to find something that I could design and iterate on with limited access to 3D printers. This meant that the 3D model had to be rendered quickly enough to start printing early, and be modifiable to an extent that iterations didn’t take days to complete.

A sketch from March met this challenge:

In the image above, I detail the three main features of the device:

  1. Tabs stick out of the back of a phone case the allow the user to coil a pair of headphones
  2. Tabs can be pushed to lock the cord in place, keeping the headphones from uncoiling
  3. Tabs do not intrude on the user’s ability to fit the phone (with its case) into their pocket

The sketch seeks to meet the need of users who frequently require access to their headphones. Dealing with this mess of cables is difficult when there is nothing for them to coil around. On the other hand, simply coiling the cables around the phone does not allow the user to access the screen:

With this design in mind, I set out to create the first iteration in Rhino3D:

This relatively simple shape was designed by drawing a series of 2D shapes and using the ExtrudeSurface command in Rhino to draw out a thin layer of 3D material. Given this design, however, I noticed that the device would remain rigid and my second feature would not be feasible. Due to the limited time I gave myself to create the first iteration, I accepted the tabs lack of mobility.

With this constraint in mind, I decided to take advantage of the fact that the assignment called for a boolean subtraction, if warranted. I decided to make a small incision on the ends of the device on which to “clip” the cord after it has been wrapped (the slot is shown within the red square):

After finishing a first iteration, I wanted to test if the third feature - the ability for the device to fit within a user’s pocket - would work in the real world.

Test Print 1 & 2

The first time I attempted to print, the shape was not watertight. This led to a few complications:

By the time the printer began to add the layer which included the cutout surface, a stringy mess ensued and the print was cancelled:

After returning to Rhino and remodeling the surfaces, I was able to print a functioning prototype:

Upon attaching the device to the back of an iPhone, I was able to test the strength of the clip and its form factor:

The form factor was slim and fit neatly into my men’s pants pocket. Unfortunately, I do not think I could print a small enough form for the average women’s pants pockets - but the same could be said for most pocket-sized products.

A Second Iteration

With the form factor in mind, I moved on to a more functional design for my headphone coiling mechanism. Since I normally use an HTC Windows Phone 8, I decided to combine my coiling mechanism with a windows phone case on Thingiverse:

The design turned out great, although I couldn’t manage to get the case to fit onto my phone. After a bit of sticky-tac and a lot of scraping (the supports don’t break themselves), I had a functional case for my device:

The case did not obscure the day-to-day usability of the phone as I wrapped my headphones around the backside:

After researching the proper ways to store headphones, it turned out that a figure-8 style wrapping was the easiest way to keep the cord in order. The inset sections of the case acted as a resting place for the earbuds while the rest of the cord could be wrapped around the device.

Unfortunately, the mechanism itself got in the way of the camera and the low print-quality that I chose allowed the clip to break in just a couple of days:

The Final Iteration

With these adjustments in mind, I set out to further improve the prototype. I went about adding another slot to the device, allowing the cable to be stored in a more secure fashion as it managed to slip out of the small clips during day-to-day use.

To address the image and strength issues, I simply moved the mechanism further down the device and deeper into the case; this provided a more sturdy (and out of the way) coiling mechanism:

After I double-checked that the model’s dimensions would allow for the full range of the camera, I went about printing the device:

The modifications worked perfectly! Not only could this new design coil headphones as efficiently as the last, the new clip solution allowed for a smaller everyday form factor due to less unravelling over time:

As an added bonus, the mechanism also acts as a great phone stand to use while viewing images and videos in landscape mode:

This bonus feature, along with the Spider-man aesthetic proved to be a great surprise as I set out to show off my case to my colleagues and classmates!

The design is hosted on thingiverse, if you’d like to print it yourself!

I’ve gotten desperate enough to start printing my own Tron merch

My library got a 3d printer that I really wanted to use, but I wanted to try modeling something myself, too. I figured Recognizers were pretty straightforward, so I figured out how to use SketchUp, and here it is! Didn’t print perfectly, but I’m still happy with how it looks. The file is here on Thingiverse, should anyone else wanna give it a go.

Our first big print with our Makerbot is finally pretty much finished. This little robot was quite something to put together. It took about a week of on and off printing to get all the pieces done. (Part of that was trial and error and having to do a couple of reprints.) We also had to do some modification on the pieces to get the pins to fit. He still needs a bit more polish work but it feels really cool to have made him.

Now I just need to get some googly eyes for him.

The Artist as a Young Man

Demitri Diosdado, an eighth grader at Voyager Middle School, in Everett, WA, won a National Silver Medal in the Scholastic Art and Writing competition for Trying to Get Out of Life. Robotics teacher Trevor Lewis writes:

Demitri fully formed his idea of what he wanted in the planning stages. We scanned Demitri multiple times to get the image just right. The process that ended up working was to take a lower resolution complete scan using an X-Box 360 Kinect sensor and Skanect software. Then we scanned in the same pose with a DAVID SLS-2 structure light scanner. The second scan had much more detail but was incomplete. Then we used Autodesk Meshmixer to combine the two scans and prep for 3D printing on our MakerBot Replicator 2. The print was done with MakerBot True White PLA and took about 8 hours with supports generated in Meshmixer.

[In progress]

Part of the 3D print is complete, so far in total, 80h of printing, need to add the glazing and the floor-plates, print the columns, add the base.  So much work to do on this but four weeks till final presentation. 

Also In the final group for the Morpholio Competition Inside 2015 if you could help me out by just viewing the project here  and other projects as well, they are very good. It would be awesome, as there are only a few days left and more view = better chance of winning.
