William Morris would have used a RapMan...

Crossing Boundaries - Art (and Textiles)

One of my D&T A level students also does Art. … and being Aaron Thorogood, one of the students who came to Euromold with us, he wanted to see if he could use 3D printing in his coursework project. So, I have to give him some credit for coming up with the idea of block printing.

I sent him away to design a block using Pro/Engineer (Creo Elements/Pro) reminding him to make sure that he “flipped” the image. A few minutes later Aaron had produced the first design and converted it to g-code with Axon. Of course this was far too easy… we found that the letters didn’t print well (too skinny) so this is where the ability to design iteratively with RapMan and BfB3000 is so valuable… Aaron produced design version 2.

Armed with some block printing ink and one of those rubber rollers that artists use for this sort of thing we inked the surface, placed the block  between some MDF scraps and a bit of leather… and squished it in a metalwork vice.

It works!!!!

Ok, we need to do some more development work on this and maybe do some research but it looks like Aaron has come up with a winning idea.

 

I then started thinking about next steps and what this block printing know-how can be used for…. And my mind has started to wonder about printing textiles. After all William Morris (English Arts and Crafts movement 1880 -1910) used wood block printing for his beautiful designs.

 

Maybe a topic for a new Teaching and Learning resource in the BfB wiki soon??

Bloodhound SSC and RapMan/BfB3000

Bloodhoundsmall

This resource is about using Bloodhound SSC as a context for designing and making using RapMan and BfB3000 printers.

Bloodhound SSC is the name of a project aiming to break the land speed record with a car powered by a jet engine and a rocket.

It is designed to reach approximately 1,000 miles per hour (1,609 km/h). It is being developed and built with the intention of breaking the land speed record by the largest ever margin.

If funding is obtained the construction should be complete by the end of 2011 and the record attempts may happen in late 2011 early 2012.

The resource contains suggested projects about designing model cars (even rocket or CO2  or balloon powered); printing a 3D map of the desert where the record attempt will take place; engine turbines; and ergonomic controls. There are cross references to other projects where more information and detail can be found.

I would like to thank Bloodhound SSC for the use of their images and ideas in producing this resource http://www.bloodhoundssc.com/

BfB, PTC and Scalextric

Two Blog posts in one day! Must be more good news!!!

 

Over the summer holidays I was contacted by PTC (the company who produce Pro/ENGINEER) about testing out some ideas for an international project that they support in schools and colleges. I couldn’t resist the challenge and the opportunities that it might offer for students.

The project is called Scalextric4schools (see http://www.scalextric4schools.org/  ). Basically students can design (using Pro/ENGINEER) and make scalextric slot cars to enter into an international competition.  Tim Brootherhood from PTC was at the DATA Digital D&T conference and wondered if BfB printers could make a scalextric car body shell.. so he sent me the files to see if it was possible (btw the Makerbot guys had already given it a go but the size of their machines means that they can only produce the body shell split into parts). As you can see from the pictures in this post with a little help from the guys at BfB we printed a body shell with support materials (those of you who visit the BfB forum may have seen some of these before when I started a discussion about twin extruders and support materials).

(download)

So, If you are looking for a new project for your school or college you might like to consider taking part in this competition, full details are on the website mentioned above.

When I get all the parts to complete these cars I’ll post some more pictures. If you have a go please think about posting some photos on the BfB forum.

Dave

PS. If you are wondering about the strange looking red car in the photos it’s a printed mould for vacuum forming car body shells... another experiment that we are trying out.

Printing with support

This resource is for the slightly more advanced. It introduces the idea of printing using support material for more difficult or complex objects

Blast off!!

How about designing and printing your own rocket.... a real one that flies! Ok so this project is about using sodium bicarbonate (baking soda) and vinegar to produce CO2 to power a model.

Thanks to "tastybento" for the use of his idea and designs on Thingiverse for this project

"How to" video.... changing settings in BfB Axon

In the previous post I announced a new video explaining how to use BfB Axon. ... Here is another "How to" video that shows how to make new profiles and change settings in Axon.

The video can also be viewed on YouTube Best viewed in HD and full screen.

Other "How to" videos can be found on the BfB Wiki  and more T&L resources are available

"How" to video... using BfB Axon

BfB Axon is a fantastic "free" program to generate the g-code to drive your RapMan or BfB3000 printer.

You can convert any .stl file generated in your 3D design software or downloaded from the internet

The video can also be viewed on YouTube Best viewed in HD and full screen.

Other "How to" videos can be found on the BfB Wiki  and more T&L resources are available

Case Study

You may have seen in the printing section of the BfB forum some of the fantastic prints that Marco has done for his company.   Forum post   The project is about terrain printing and a hydro-electric dam.

Case_study_dam
Marco (Sigma Design in Italy) very kindly sent me some designs, drawings, photos and information about this project to enable me to produce a case study.

This type of case study is extremely valuable for students as it shows them how 3D printing is used "in the real world" of business and industry. And of course the prints were done using a RapMan   

The link to this case study is here- Case Study - Dam project

... and of course a huge thank you to Marco for sending me the files and information that made this possible.

Dave
PS. If anyone else has similar information about a "real world" project that they wouldn't mind being made into a case study then please contact me and I will put together a .pdf that can be used in education.... and of course your business will get a free advert

Print your own DNA

This time about DNA and the double helix.  http://www.bitsfrombytes.com/wiki/index.php?title=Science_-_DNA

Dna

This resource is heavily based on the work by "Cathalgarvey" on Thingiverse... my thanks to him for producing the .stl files (and to Bogdan for spotting them and realising it would make a good T&L resource)

Promoting RapMan

This PowerPoint can be used to help demonstrate the use of RapMan and the resources that are available (such as the forum, wiki, T&L Resources, etc)... useful for open days, conferences etc.

Note to use this PowerPoint to best effect you will need to install the font "Neuropolitical".... font download  

PowerPoint   (.... this time supplied as a PowerPoint, please feel free to edit, modify and adapt as necessary.)
