Come One Come All

WOOF will be hosting a "Come One Come All" meeting to introduce UW Students to Washington Open Object Fabricators and the opportunity for hands-on experience in many different disciplines, including (but not limited to): mechanical, materials science, computer science, and electrical engineering.

If you are interested in the many opportunities available to someone with experience building, using, or developing additive manufacturing technologies, join us for our "Come One Come All" meeting; Wednesday, October 9th, 2013. We will start the meeting at 5:00PM in MEB 103, and follow up with a tour of our club workroom in MEB G045.

Project Mondays

The quarter has started and we're busy here in the WOOF room. We have 2 large format printers we are working on now: Big Red and the Kilobot.

Here is a part of the redesign for Big Red's z-axis. 
Mondays at 4:00 PM will be dedicated project time this quarter. Any experience level welcome.

It's still summer... We're still working!

Here's a teaser of something that's been a long time coming...

Stay tuned... We've got some exciting stuff in the works!

Moving Madness

Open Build Friday is cancelled tomorrow due to our in-progress move from MEB 252 to MEB G045. If you want to come help us move, we will have someone in one of the two rooms from 2:00pm until 5:00pm doing moving related things.

For those of you that don't know where G045 is, it's on the ground floor, which is below the 1st floor, near the rapid prototyping lab. Hope to see you there!

Seafair was a huge success!

A huge thanks to everyone who came out to Seafair! We're working on getting a bunch of pictures all together, but for now, here's a notable one:

Way to go WOOF!

Friday, July 12, 2013

It's nearly boat time!

Hello all!

We just heard from the folks at Seafair, and we'll be showing our boats in the Parade of Boats at 12:30pm, and racing at 1:15PM after the military category. We'll be racing last years boat against the new boat from this year.

Come on down and show your support for WOOF and additive manufacturing. Wear your UW colors!

It's been a long process, and Big Red has become quite a bit easier to work with. We'd also like to thank everyone that helped out along the way, from our milk jug collectors to our sleepless printer operators, we couldn't have done it without your contributions.

Planning and pre-heating

The first layer needed a lot of pre-heating to improve adhesion.

Building the walls!

Once the walls were built up, the heating element alone was sufficient for adhesion. Much easier than last year's printer!

Even with the heating element, the HDPE would cool and shrink. Our boat's geometry changed significantly, so we used supports to continue printing.
Eventually the warping got too bad, and we had to stop printing. Our boat is a cool 9.5" tall, and looks great!

Again, a HUGE thank you to everyone who supported us. We couldn't have done this without you! We'll see you at SeaFair!

Two Important Things


Due to our focus on printing the boat this week, we will not have open workroom hours this Friday.

Second (and more important):

WOOF is relocating. We have been reassigned to room G045 (just two floors down in the MEB). Beginning next week we will be moving to our new work space. This is a great opportunity for us to "clean house".

There are many of us who have property in the room (tools, printers, printer kits, etc.). We know many of you aren't around for summer quarter, but if you are local we ask that you come in and remove your stuff ASAP. If you aren't local (or can't make it in soon) please contact the officers so we can account for everything. The new room is smaller so we simply don't have the same capacity for storing things that aren't being used. Also, the less clutter we have to deal with the easier it will be for everyone during our transition.

I hope you have been having a good summer so far and don't forget to be awesome.

Summer Workroom hours

Hey you WOOFers! Our summer workroom hours are still every Friday, from noon to five. Come in and work on your projects, help with the boat project, or just hang out!

Monday, June 10, 2013

Workroom Hours This Week

Hey WOOFers,

Some of you have asked about when the workroom will be open this week. We will have at least one officer in the room after noon on Wednesday, Thursday, Friday, Saturday, and Sunday. If you need help finishing your Grawmet 2 or want to help out building the boat come on in and get some work done. Good luck with the rest of your finals.


Friday, June 7, 2013


This is to remind you all that Seattle Mini Maker Faire is this weekend! It is Saturday and Sunday from 10am to 6pm located at Seattle Center. College students qualify for the student discount which means a day pass is $10 at the door.

Take a break from studying for finals and check out what awesome things other local makers are doing.

Sustainability at UW!

One of our "things" here at WOOF is recycling. Big Red feeds on the delicious flakes of milk jugs that we collect from the community. But milk jugs are hard to deal with. They're mostly air, so you don't get very much material per jug, they shrink a lot when you print with them, and they smell terrible.

We have been quietly experimenting with grinding up the forks, spoons, and knives used on the UW campus, for use in large scale 3D printing. The iconic brown utensils are made from a biodegradable plastic, PLA (PolyLactic Acid), which lends itself quite nicely to 3D Printing. Our goal is to divert these utensils from the waste streams and into our workroom!

To this end, WOOF has partnered with the UW Garbology Team! They have a ton of experience with the waste stream on campus, and we are very excited to help one another out. We're hoping to use this material to print some composting bins, which will, in turn, generate more plastic for us to print more bins... A never-ending cycle!

We've got a collection bin set up in Ian's Domain, located in McCarty hall, and hope to expand to some other caf├ęs on campus. Please consider dropping your forks and spoons in the box (And keep it clean of other stuff, too!).

We're very excited for what the future holds with this plastic. Stay tuned!

(Our first print with the forks. Not too shabby!)

Grawmet 2 Kits Are Ready!

The Grawmet 2 kits have finally been gathered and are ready for assembly. Today we will have our first assembly workshop. Here's our schedule:

12:30 - The workroom will be open. Pizza will be present. This is a great time to come in and familiarize yourself with your kit contents.

1:00 - The first intensive assembly session begins. We will lead you step-by-step through the first stage of the build (up to the extruder).

3:00 - The second intensive assembly session begins. Same as above. This is for those who can't make the earlier one. Like the first session we suggest showing up early to become familiar with your kit.

5:00 - Clean up.

It is highly recommended that you plan to attend an entire assembly session from start to finish. It will make things easier for you and us. This is not to say that you can't assemble your bot if you can't make it, but it will take more effort and initiative on your part. That being said, we're excited to see you today. Hopefully we can get all of these bots up and running before summer break.

Any WOOFers adept at video editing?

Hi all,

While the parts for the Grawmet 2 continue to arrive it's time for us to create our video assembly guide. We will be doing a complete assembly of a Grawmet 2 from start to finish on video while explaining each step. We hope this will help in two ways. First, G2 builders will be able to view these videos before they come to build days to help them understand what they'll be doing (and hit fewer stumbling blocks). Second, any G2 builder who can't make it to the build days should be able to follow the video guide to finish their bot.

Here's where we need help. We need a WOOFer (or WOOFers) with video editing experience to edit the footage into easy to follow steps. It's a bonus for us if you can help collect the footage. It's a super bonus for you if you have ordered a G2 kit (just think how well prepared you'll be to fly through assembling yours).

So any of you who are decent at video editing and are willing/able, please reach out to me directly and we can discuss how to go about this. You can reach me at or stop by the WOOF room and see if I'm there.

Thanks and don't forget to be awesome.

Finishing Your Grawmet 1

Hey all,

There are a number of you who have not finished your Grawmet kits. We realize that there a few reasons this has happened like classes, schedule conflicts, and/or uncertainty of how to proceed. We want to help you finish up so we're trying something new.

On Mondays after the general meeting, we will begin having structured intensive build seminars. What these will consist of is a few experienced Grawmet teachers leading a group of builders through a specific stage of the build.

The general meeting starts at 4:30. After club business is taken care of we'll start to rock on the builds. Our schedule is as follows:

6 MAY - Base
13 MAY - X carriage
20 MAY - Extruder

After all of these seminars you will be ready to start printing and calibrating. You'll finally be ready to start printing off your own parts on your own machine!

How to get a Grawmet 2 kit.

Hi WOOFers,

The time has finally arrived for us to assemble a club order for Grawmet 2 kits! I know many of you are chomping at the bit to get one. Here's what you need to know:

> The kit cost is $325.

> The money is due by 5:30 pm on Friday. We start writing the orders on the weekend so if you miss the deadline then we can't order a kit for you this time. You'll have to wait until Autumn quarter at the earliest.

> The preferred tender is check. Checks must be made out to Washington Open Object Fabricators. If you don't have checks then we can take cash, but we'll need to have an extra witness to sign off that the transaction did take place.

> The only person who can accept payment is Mark Hanson (the treasurer). He will be in the WOOF room all week. The times are as follows:
TUE:   9:30 - 1:30
WED:   9:30 - 11:30, 12:30 - 3:30
THU:   10:30 - 12:30
FRI:   9:30 - 11:30, 12:30 - 3:00, 5:00 - 5:30

> We anticipate a lead time of 2-3 weeks.

This time around we aim to have a quicker completion rate than we experienced with the Grawmet 1. We're excited to get more club printers to our membership to spread the good work of 3DP. Keep being awesome!

-Mark Hanson

WOOF's a Hit at Engineering Discovery Days

I want to start off by thanking all of our volunteers for helping out Friday and Saturday.  You guys did a fantastic job and we had many a child leave that room with 3D printing sparkling in their eyes.

Thank you

WOOF saw several hundred children and their parents come through the workroom over the course of the two days.  We got to show off some of the printers that our member's built, a frostruder that prints in playdough, and Big Red setup as a poster plotter.

Some pictures from the event:

This Friday (April 26)

Hey WOOFers,

This Friday is Engineering Discovery Days.  As WOOF will be participating, there will be no open workshop that day.  You are more than welcome to come by, hang out, and/or help out.

I will be taking the first 10 people who sign up for time slots on the Doodle poll:
as official volunteers for Discovery Days.  Official volunteers get a t-shirt and pizza - so sign up soon!

Engineering Discovery Days Volunteers Needed!

Hey Fabbers,

WOOF is participating in this year's UW Engineering Discovery Days and need volunteers to help out.

Discovery Days is April 26 & 27 and we will need at least three volunteers every hour:
Friday April 26:
     Setup: 8:30 - 9:00
     Event starts: 9:00 - 2:00
     Clean-up: 2:00 - 2:30
Saturday April 27:
     Setup: 9:30 - 10:00
     Event starts: 10:00 - 2:00
     Clean-up: 2:00 - 2:30

I have created a Doodle poll with each hour option.  Please sign up for times that you will be helping out.  No need for any prior 3D knowledge, we are happy to teach you everything you need.  I have limited the number of people that can sign up for each hour to three obviously the more the merrier, so if a slot is full just show up.  We MUST have three volunteers every hour.

After you have signed up, please send me an e-mail with your name and the time you signed up (so that I know who to hunt down if you don't show up)

All the little kiddies thank you!
Bethany Weeks

WOOF's Second General Project Discussion

Hey you WOOFers!

Our second General Project Discussion is happening tomorrow, February 25th, from 4:30 to 5:30. It will be held in MEB 242 (NOT our normal workroom). Hope to see you there!

These discussion will be a weekly thing hopefully, so if you can't make it this week, just come the next!

Tuesday, February 19, 2013

General Project Discussion

Just a quick reminder, there will be WOOF's first ever General Project Discussion in MEB 242 (Not out normal workroom!) tomorrow, February 19th.

We're starting at 4:30, so feel free to stop by and see what's up! We'll be introducing some club wide projects for people to work on. These are projects that will be funded by WOOF, so it's a great opportunity for anyone who is new to 3D printing, and doesn't want to purchase a Grawmet kit just yet. Some projects that we're considering are designing the milk jug derby boat, and building a 3D scanner.

Come on down, have some snacks, and join in the discussion!

See you there!

Notice of Room Use

The ME department has been very kind to allow us to use ME 252 as our home base. This term, the ME 356 class will need to use the room for approximately 3 weeks for a class project. In order to help make the room work well for ME 356, we are asking all WOOF members to remove their personal belongings from the room. This means printers, parts, tools etc. The more stuff we can temporarily remove,  the easier it will be for ME 356. Let's make it as convenient for them as possible so that we are welcomed back. Any items that are not removed will be temporarily hidden in Big Red or stored along the window sill.  This all needs happen by this Thursday. Sorry for the short notice. If you'd like to pick up something and need to be let into the room send an email to any of the officers or email

During the next few weeks, plan on having very limited access, if any, to the WOOF room.

Please spread the word. This needs to happen this week.

First Grawmet Print!

That's right! The Grawmet kits are finally getting to the point of printing!

WOOF member Bing had the following to say about his Grawmet:
Here it is! My first somewhat successful print with the Grawmet - a BOX! Since the thing isn't calibrated correctly the box is very squished along the Z-axis.
Way to go, Bing!

The first working Grawmet!
