The new book by +Whosa whatsis and me,  "3D Printed Science Projects," has gotten a great start- thanks, everyone! Here's another one of the models from the botany chapter. This one prints (in pieces) without support to show how jungle plants optimize their use of what sunlight they manage to get. ‪#‎scientificmakers‬ 
And by the way, we will be teaching a four week beginner 3d printing class online starting June 5. Still time to sign up at www.nonscriptum.com/classes.

The latest book with +Whosa whatsis  is now available for purchase! Thank you to all the folks who gave us great ideas, encouragement, a flat place to put down a laptop and/or food during the writing process... we have been really excited about how interested people have been in this book and hope it makes a real impact. It's the first book with objects designed to be changed in a way that allows for science exploration instead of just downloading a model that can't be changed.

Just submitted Hackaday prize entry with +Whosa whatsis  - check it out! https://hackaday.io/project/11312-3d-prints-for-teachers-of-the-visually-impaired
Visually impaired students can have difficulties learning many subjects. 3D prints offer an unprecedented asset for their teachers, and 3D printers are becoming available for these teachers. But they need help creating models that aren't just pretty, and are tied to curriculum. Along with [Whosawhastis] I have been mentoring some groups volunteering to create models, including students at Pasadena City College in summer 2015. Last year we suppor...

The award for the coolest new thing I saw at MRRF this weekend goes to the Kitten 3D printer. It's aptly named, this tiny tantillus-like printer is so cute, and was getting great results (especially considering the fact that it uses printed PLA linear bearings for X/Y). For scale, those are NEMA14 motors and 15mm aluminum extrusions. Print area is about a 100mm cube. Another interesting feature is that they were able to over-drive the motors a bit by putting thermal pads on them to allow them to use the aluminum frame as a heatsink.

I hope they start printing the parts out of something other than PLA. It's pretty cold around here, but those PLA motor mounts definitely won't survive in a warmer climate.

Very excited that +Whosa whatsis and my new book is now up for preorder:  "3D Printed Science Projects: Ideas for your classroom, science fair or home."

This book shows parents and teachers how to use the models inside as starting points for 3D printable explorations. Students can start with these models and vary them for their own explorations. Unlike other sets of models that can just be scaled, these models have the science built-in.

That means that a busy teacher can just print a model for her class to pass around, or an ambitious student trying to do a great science far project can build on them. We have a "Learning Like a Maker" section in each chapter about what we, the authors, learned by making the models. We found that almost all textbooks have variations of the same 2D sketch for 3D (or more) concepts, and when you go to 3D you have to think differently and you learn a lot.

The book cover image is from our plants and ecosystems models, where we allow you to "design" a  plant or flower.

Topics covered:
3D Math Functions
Light and Other Waves
Gravity
Airfoils
Simple Machines
Plants and their Ecosystems
Molecules
Trusses
So far it is just available at Apress and through Apress' parent, Springer-Nature, but between now and the planned May release it will propagate to other places computer books are sold.

Preorder: http://www.apress.com/9781484213247?gtmf=s

To create the models, we pestered a lot of scientist friends as well as dusting off my textbooks and spending a lot of time in libraries. Thanks to everyone who made this happen, and is helping us with the last pieces as we scurry to meet our deadlines!

We will be posting more about it as we get closer to the full release. Thanks to our friends at MatterHacker    for their enthusiasm for this project, too!

We ( +Whosa whatsis  and I)  are going to be hanging out at the MatterHackers booth at Bay Area Makerfaire in San Mateo. We will be there for sure at noon and 3 PM on both Saturday, May 21 and Sunday, May 22nd, to talk about our new book from Apress  ("3D Printed Science Projects.") Hope to see you all there!

My business partner +Whosa whatsis  and I are the co-organizers of the first American Association for the Advancement of Science (AAAS) Pacific Division Scientific Maker Symposium and Exhibit. We invited scientists who are using maker tech like 3D printing and Arduinos to present their work and how that turned out for them. We got a very interesting response across a spread of disciplines, and expect a dozen exhibits and a long afternoon of papers.

The program will be held as part of the AAAS/PD annual meeting. The overall meeting runs Tuesday, June 14 through Friday, June 17; our program is on Thursday the 16th. It will be held at the campus of University of San Diego.

To see the list of talks in the symposium, see http://associations.sou.edu/aaaspd/2016SANDIEGO/Symposia16.html#7

For general information about the conference, and for a link for registration, go to http://associations.sou.edu/aaaspd/2016SANDIEGO/index.html

Hope to see a lot of  #scientificmaker activity!

 I wanted to put out a last call for submissions for  an event  +Whosa whatsis  and I are  co-chairing n San Diego June 16th. Our event is a showcase of  DIY science and scientific maker projects; it will be part of the larger American Association for Advancement of Science (AAAS) Pacific Division annual conference. If you know anyone who is working to lower the cost of doing professional science or to enable citizen scientists to build their own equipment, we would love it if you could pass this on.  Examples would be using consumer-level 3D printing for prototype or real equipment, Arduinos to run field sensors, etc.

Applications to give a talk are due April 1, and to exhibit a maker project, April 22nd  Time and space are pretty limited (it's a pilot!- we just have one afternoon for talks and one big room for exhibits) but I am hoping to get some great DIY lab and open-source citizen science.

We now have a simpler form to apply for a spot to exhibit or talk, and links for more info:

By popular demand, the arc gimbal I showed off at MRRF is now available on Youmagine.

I'm now very slightly less behind on getting my designs posted!

I've been giving a lot of thought to what type of linear bearing to use for a Z axis. When mounted vertically, these bearings either have no gravitational preloading or, in the case of a cantilever, gravity creates an angular load. In a cantilever, any angular play in the bearing will be amplified at the far end, so it's important to use a bearing that is very rigid. I was looking at all of the printers at MRRF, and most seemed to be using whatever type of Z axis bearing they were using in a sub-optimal way. Even the Clone R1, which used HIWIN-style MGN bearings for the Z axis had them mounted in a direction that I suspect was not optimal for this purpose. I suspect that rotating these bearings 90 degrees so that the platform hangs off the side of them would work better for this purpose.

Of course, using a longer bearing or multiple bearings set further apart will help, but you also lose travel this way, so the machine needs to be taller for a given build height.

Anyone know of any data that's been collected on how various types of linear bearings handle angular loads from various directions (particularly interested in data on MGN-series linear rails).

I agree that having two carriages is the optimal solution. Depending on what size rails and carriages you go with, you could have a pretty compact system. However, you could achieve is a very similar effect by using a single wide rail with an extra long carriage. It would never replace a dual rail, dual carriage system, but at some point you'll be spending more money on a better system bit you won't see a difference in quality of the print. Or reliability of the printer.

There were a bunch of printers trying to make my gear bearings at #MRRF  this weekend, including the Part Daddy (although its pellet feed failed when we all left for the night).
