3Dougher:

the world’s first 3D printing dough device

Many hacker and maker spaces have been exploring new 3D printing devices and systems.   We even spent quite a bit of time exploring new material systems.

We all come back to wanting to 3D print food.    Ever wanted a hand-held device that would allow you to make 3D creations at the touch of a button.

Introducing the 3Dougher…

3Dougher. This electric dough dispenser allows your to take your 3D cooking skills to new levels.  Simply load the 3Dougher with your favorite dough or toppings and squeeze the trigger.   You are off 3doughing.   Included with 3Dougher are 12 different extrusion discs and three nozzle tips for the ultimate 3Doughing experience.

This simple tigger will set you free…

Let your 3Doughing go wild:

This product has been in development for quite some time.   Shown below is one of the early manual test models.   As you can see, we come a long way to bring you the 3Dougher.

Why not 3Dough some liver pate’ (or crab spread) on a cracker?

Over the past couple of months of Saturdays, several of us have gotten together to build some plastic PrintrBots.    I printed the bag of plastic PrintrBot  parts for them (in traditional RepRap fashion).   I gave them some pointers to Brook Drumm’s excellent videos of PrintrBot assembly.      I observed the overall process happen and was amazed.  So many questions. “What’s a BOM?” “Why isn’t there just one BOM?”  ”Why  do the BOM’s change almost daily?”  ”This is the fourth time I’ve taken the X carriage apart, Why?”   “Why do two of my motors have different color wires than the rest?”   “What, I can’t see that… Where are my glasses?”   And MANY MORE…

None of the original team had ever really seen a DIY 3D printer up-close and personal.    It was fun.    Two Saturday’s ago, the first printer started to print!  We even had a member or two from the WOOF team stop over.  While, we just about have all bots up and running, the discussion turned to “What bot should we try next?”

Remember, you don’t stop playing because you get old…. you get old because you stop playing.

Last year about this time, we had another meeting to discuss the teaching foot model.

Ledoux’s idea was much clearer.

“The primary purpose of the 2x foot model is for demonstrations during lectures. Often times, I will want to point to a specific bone or move a joint through a range of motion. This can be difficult to effectively perform with a typical commercially purchased foot model, which is about 20 cm long, as those beyond the first few rows of the room cannot see the demonstration. This issue is easily avoided with the 2x foot model as the bones are clearly visible from the back of most rooms.”

This time the idea was to create a twice size model of the bones in the foot which would allow articulation of each bone.    Again, the idea seemed straight forward.   A team of two students went into planning mode to create/model and then 3D print each bone in the foot and then connect them using flexible cord to allow movement.   The models was constructed from CT/MIR data.   The result is quite startling.

We know the Prof. Ledoux often asks students in lecture to guess how much larger than life is this foot.   He waits for the respones with a smile.

3D printing or Additive Manufacturing allows for change of object scale almost for free.   The result can make a big impression.

Here we have Corwin showing off that new interview look.

We asked Corwin “How did it go (with that tie)?”   His response “Folks thought it was pretty cool!”

Haven’t you always dreamt of having miniature, edible figurines of yourself? Yeah, neither did I. At least not until this possibility became a reality in one of my classes last quarter. Taking ME480 (one of our AM classes) with Professor Storti opened up endless possibilities for creative gifts… assuming your friends would enjoy, quite literally, biting your head off  (like mine did).

Food friendly molds were used to create the gummi and chocolate figurines.  A two sided mold set was required to create the figurine of a single person (one for the front and one for the back, which are put together to create a mold for the full body.)

The process to create these molds began by 3D scanning ourselves using the Microsoft 360 Kinect scanner in the lab and ReconstructMe software (. These scans were then imported into Rhino3D to create the inverse of the desired final molds. Once the 3D model was completed, they were printed on the 3DP powder printer, also located in the lab. Below you can see the mold parts — one intact and another that was not so lucky. These molds halves together create the full 3D figurine. Both of the parts below have been waxed after being printed on the 3DP powder printer.

A  food-grade Silicone mold material was then poured into these 3DP printed parts to create the final molds. The final molds (the pink squares below) were used to create various kinds of edible figurines. First up: melted gummi bears.

The first run of gummi bears was not very successful. Without using any type of non-stick spray the gummi figurines were really hard to remove from the molds and looked more like an elongated Stretch Armstrong than a person. The next round produced much more desirable results. For this more successful batch, some standard non-stick spray was used before putting in the melted gummi bears and the molds were allowed to set overnight.

 Next up: chocolate. Only one chocolate mold was attempted and it cracked, unfortunately. Others in the class were more successful in their chocolate casting endeavors than us. Below you can see some of the attempted casted figurines. Helpful hint: Don’t leave these out on the counter when your roommates are hungry.

We should all enjoy having the spot light on us as the current shiny thing.      However, I was reminded by a song “Everything Old is New Again” by Peter Allen (and  Carol Sager).  My personal favorite version appears in the movie “All that Jazz“.

EVERYTHING OLD IS NEW AGAIN

When trumpets were mellow
And every gal only had one fellow
No need to remember when
Cause everything old is new again

Dancin’ at ya
Long Island Jazz Age parties
Waiter, let me have some more Bacardis
Let’s order now what they ordered then
Cause everything old is new again

Get out your white suit,
your tap shoes and tails
Let’s go backwards when forward fails 
And movie stars that you thought were long dead,
Now are framed beside your bed

Don’t throw the past away
You might need it some rainy day
Dreams can come true again
When everything old is new again

Get out your white suit,
your tap shoes and tails
Let’s go backwards when all else fails
Leave Greta Garbo alone
Be a movie star on your own

And don’t throw
Don’t throw the past away
We’re all gonna need it some rainy day
Dreams can come true again
When everything old is new again

I might fall in love with you again

We hope that as a community we don’t forget the shoulders that we’ve built upon “everything old” and we all work hard to be “a movie star on our own”!

Let’s fall in love with 3D printing and AM all over again this year…

Wiffle = Box[4,4,4]-Sphere[2.35]+Sphere[2.00]

We sneaked a peek  into the toy-land workshop (when the elves weren’t looking) or maybe there was a little too much holiday cheer.

What to our wandering (and wondering) eyes did appear?

Introducing the “BrainWave board” or the little orange board.   This is an all-in-one  3D printing bot board with support for 4 stepper motors, a heated extruder and a heated print bed.

As we looked around the workshop, we spied a pile of boards ready to be boxed to go out to good-little girls and boys.

We spied the easy-bake board baker ….

And the board tester…

The rumor has it that the orange BrainWave board was designed, fabbed, pick-and-placed and tested all  in the NW.   Way to go elves (especially the low price).  Thanks for making those bot wishes come true!

Ho, Ho, Ho…Holidaz

‘Twas the night before Printsmas, when all through the house
the creatures were stirring, and using their mouse;
The filament was hung by their printers with care,
In hopes that amazing prints would soon be theirs;
The kaptan was nestled all snug on each bed,
while visions of heated plates danced in their heads;
And burgers from Dick’s, and drinks from the bar,
I knew twas a long night of tweaking so near and so far.
when out on the lawn there arose such a clatter,
I sprang from the makerspace to see what’s the matter.
Away from my PC, I flew like a flash,
halted the print and was totally aghast.
The moon on the glass of the new print bed low
gave a sparkle to objects printed in day-glo
When, what to my wondering specks should appear,
But a miniature bot, and eight boxes of new gear,
With a little old printista, so smart and so quick,
I knew in a moment it wasn’t old Rick.
More rapid than sprinter or tea cup the same,
And he cursed and shouted, and flashed each the same;
Flash MakeBot! Flash Huxley! now Prusa and Mendel
On PrintrBot! On Grawmet! on Wallace and Clonedel!
To the top of the memory space! To the top of the RAM!
Now flash away! flash away! flash it ka-bam!
So on to the new printers, with marlin they flew,
With a build space full of toys, and a octopus too!
As new parts and plastics arrived by UPS,
ripped open the boxes and made a huge mess,
So back to the web sites, more orders to place.
And then, in a inkling, I heard on the blog
The whinning and crying of each internet dog.
Down to the hackspace they came with a bound.
They were dressed all in t-shirts, and some with rain capes
And their bots all were decked-out with LED’s and tapes;
A bundled of wires from motors to board,
And they looked more like messes not really to hoard.
But their print speeds — moved plastic! With colors like cherry
Their motors were warm, and carriages like flairies.
The new print boards so little so orange and so low,
And the firmware to flash as crazy as Joe;
The heat of the hot end held tight in each Wades,
And the smoke which encircled let all be amazed.
Each a sprung platform with belt driven carriage
that shook, when they printed like folks before marriage.
There were newbies of wonder who were seeking some help
from old ones with wisdom even caused some to yelp.
In a wink of her eye and a twist of a pot,
soon gave me to printing and right on the spot.
Some spoke not a word, but went straight to their prints,
and made parts and/or videos to give others hints.
And laying their fingers to the pronterface keys,
and giving a nod, up the slic3r speeds with ease.
We sprang from the web, to ours printers fed code,
And away they all flew making another commode.
I heard some exclaim, at the end of the night
Happy Printsmas to All, and to all Print it Right!

The turntable was built from a $10 bearing from the hardware store, and some bits of wood and hardware lying around the Mechanical Engineering building.

The person being scanned stands on the turntable while a second person pulls the blue cord to spin them around. As the turntable spins, it draws the Kinect up from the floor.

We’re using Reconstructme to process the data from the Kinect into a 3D model. After playing around with some config files to set the parameters of the scanning envelope (to get every part of the person, but not the floor or ceiling), it’s actually pretty easy to clean up the resulting file in Netfabb Studio Basic.

And here is just a small subset of the people we’ve scanned so far:

All the students in one of Professor Storti’s classes have been scanned.  They are exploring the difficulties of processing mesh data with a large number of triangles.     Stay tuned for more objects processed by our Scan-O-Rama.

The 3D4D Challenge: Relieving Poverty, Encouraging Innovation

“Do you have a transformational idea that could leverage 3D printing technologies to deliver real social benefits in the developing world?

Would you welcome the chance to work with great people to develop your idea further?”

The winning idea will be the one that stands out because:

It clearly and measurably addresses a significant social need e,g, improving the incomes of some of the world’s poorest people or improving access to clean water or energy.

It demonstrates real technical innovation.  In other words, it brings together leading edge thinking across mobile, web, manufacturing and solar technologies.

It clearly demonstrates that there is a sustainable business model that underpins the idea; not simply a reliance on continual donor funding.

They placed as finalists and traveled to London this past week to compete for the grand prize.   We cheered as we watched their presentation live in one of our classrooms.

WOOF’s idea “will enable waste plastic to be used as filament for 3D printing machines, to create new products. The winning team, Bethany Weeks, Matthew Rogge and Brandon Bowman, plan to work with US based NGO, Water for Humans (WFH), to address local issues in water and sanitation in Oaxaca, Mexico.”

We are all excited for their return to celebrate their Grand Prize finish!   Truly amazing!

Congratulations to our WOOF team with an outstanding start of this school year.
