Making print cartridges for a Z400/Z402 3D printer

One of the costs of running an inkjet based 3D printer is that the cartridges have to be replaced on a regular basis. The Z400 and Z402 use Canon BC-20 ink cartridges which are readily available.

There are currently two known ways of making these cartridges ready for the printer.

The first method is to cut the cartridge in half, remove the foam inside, cut a Blue Falcon BD-50 Centrifuge tube in half, and epoxy it and a small O ring to the reservoir at the bottom of the cartridge. This is how the cartridges that are sold by Z Corp are made.

An alternative method is two drill two holes in the cartridge, epoxy down some type of barb, and flush the cartridge. This is the method I am currently using in my Z402. Click below for full instructions and a few pictures of the process.


Freeside Buildout 7/9!

Hey, this is Pepper! We got a lot of clean up work today! We painted the kitchen and the back hallway. Work was done, accomplishments made!









We also painted the back hallway wall a lovely chartruese (bwahaha) and took care some of the less seemly graffiti. Next buildout will be scheduled in the near future! :D

Open House this Saturday, June 11th

Miss all those Tuesday meetings because you don't live close and hate downtown traffic? Here's your chance to come check us out on a weekend!
There will be plenty of members hanging out at the space doing stuff that interests us. (3D printing, metal pouring, etc). Stop by and hang out.
All day Saturday (11Jun).

Bring projects to show off, or projects you'd like some advice on. Bring friends and friends of friends! Weather permitting, there will be grilling.

This event is FREE and OPEN to the public. Like all of our events, donations are appreciated. Children must bring their parents in order to attend.

Concrete Countertop

Freeside is a great space, but our kitchen could be charitably described as "needs work". The countertops are old, difficult to keep clean, and just generally bad. What the heck, we're a hacker space, right? Lets hack some countertops.

Open Source 3D Printing Meetup.


Freeside Atlanta will be hosting an Open Source 3D Printing meetup. Like most events at Freeside this will be free and open to the public. We will have a number of 3D printers on hand to show off and will be building a new one during the meetup. This is a great opportunity for people to learn more about 3D printing and to see some printers in action. There will also be a special guest who operates ultimachine.com and has built a successful business around this emerging technology. Hope to see you there!

When: December 4th 2010 @ 10am

The Egg Bot is Alive



I finally had some time (around 2 hours or so) to sit down with the Egg Bot and work with straighting everything up and finally getting a good egg out of it. Trying to go to high or low on the egg just stretches the image out and makes the design on the egg look terrible. (see our first try of the FreeSide Logo on an egg )
Different colors are done by creating layers in your image (like in photoshop), The software allows you to print one layer, change the color marker and then print the next layer, while remembering where it's at on the egg. As you can see in the above video, it works pretty well.

Sufficeintly retro technology is indistinquishable from science fiction

I came across this lovely bit of lost knowledge while cleaning out the space last week:


Wire recorders were a big deal in the 40's and 50's. They work by storing sound magnetically on a thin steel wire. The sound is great. The recording playing in the clip was taken off WSB radio almost 70 years ago and recorded to the wire. It sounds as if it was fresh off the air.

So why did this interesting spinning box go away? Several reasons. First, when you can cheaply make tape or vinyl, who wants to sell the latest top 40 hits in several hundred feet of steel wire? No one.

Next, hear that recording? Good, because that is the last time that particular wire will ever play. On the rewind it became tangled and unusable. Further research shows that this was a typical issue for users.

Finally, newer, better, and cheaper tech came out that spelled death for the wire recorders. Sure it survived a little while as a dict-a-phone or in radio studios, but in the end wire lost to tape.

Now if I can only find out who brought this in so I can give him/her/it credit...

Free Classes this Weekend!

The Freeside Calender is full of great classes this weekend including:

* MakerBot Operation @ 1pm-3pm Sat. 9/25/2010
* Python 101 @ 4pm-6pm Sat. 9/25/2010
* Welding (Full) @ 11:30am Sunday 9/26/2010.

This weekend's welding class is already full, but if you are interested in attending a future welding class just show up to our weekly meeting on Tuesdays @ 7:30pm to register. The MakerBot and Python classes are both free and open to the public, so feel free to show up and bring a friend.

Please keep in mind that your donations are what allow us to keep doing these classes for free.
