Yesterday Simon and Richard, along with several of our THREEDY 3D Printers, had a great day out at the Cambridge Science Centre for this fantastic event. Code & Chips 2016 was a day of technology workshops and exhibitions aimed at getting students from Year 4 to 8 (8 to 12 year olds) skilled up and excited about a career in STEM (Science, Technology, Engineering & Maths).
A big thank you to HackLab and ARM for giving us the opportunity to participate in this event. We love seeing our young engineers of the future being inspired by STEM activites – and what better day for it than Ada Lovelace Day; an international celebration day of the achievements of women in science, technology, engineering & maths.
We are excited to be once again hosting a fantastic day sharing interesting puzzles, maths, magic & science.
Letchworth Garden City, Hertfordshire
Saturday 22nd October
What is G4G?
Martin Gardner was an American writer who pioneered the field of recreational mathematics for many years. He died in 2010 and since then Gathering for Gardner (G4G) events have been held around the world, usually in October, to celebrate the types of pursuits he made popular. You can read more about these events at http://celebrationofmind.org
The focus is on sharing interesting things in the related fields of:
What happens at the celebration?
The day will include a series of 5-10 minute talks as well as the chance to browse various tables of interesting objects with the opportunity to play with a wide variety of 3D puzzles and have a go at various mathematical puzzles. Attendees are encouraged to contribute to the display tables or to give a talk.
What will be there?
Activities and display tables are expected to include 3D puzzles; mathematical origami; optical illusions; 3D printing; mathematical conundrums; challenge games (eg rush hour). The 2016 talks will be listed soon. The C4G COM Letchworth 2015 talks included:
how to make impossible objects
easy way to understand Tower of Hanoi
how the Infinity puzzle was solved
Interested in attending? Please let us know and we will send you an invitation. Please then RSVP so that we can update our numbers. Also, let us know if you would like to give a talk or contribute to the activities and displays.
The children were back to school this week. In preparation (and with hope of increasing the chance that they will return home with their own belongings) THREEDY 3D Printed these personalised name tag labels.
When metagrobologist David Singmaster gave his talk on Impossible Grilles at MathsJam 2015, it inspired Simon to print some of these “impossible objects” using the THREEDY 3D Printer he happened to have to hand.
Whilst travelling around medieval cities, particularly during Italian holidays, David observed the heavy grills over windows of buildings. Many years ago, he noticed that the bars at the centre formed a pattern which seemed to be impossible to assemble. This “impossible” grill pattern is also depicted in M.C. Escher’s Belvedere print.
David later saw that this central area could be assembled by a simultaneous converging process but the pattern continues and this made his idea fail. David showed his idea to James Dalgety, who proceeded to make an example from heavy wire; David then saw how to assemble the whole pattern easily.
The grill rods are printed individually, then slotted together – simple as that!
A belated thank you to David Singmaster for his inspiring talk.
Simon and his family enjoyed their summer holiday walking the West Highland Way – yes, all 96 miles of it. Greetings to the physicists from University of Munster, with whom we shared these Ambiguous Cylinders. The ambiguous cylinders were printed on a THREEDY 3D Printer, with kind permission from Kokichi Sugihara. This illusion was designed by Kokichi Sugihara and won second prize in the Best Illusion of the Year Contest 2016. More info (and other fantastic illusions) can be found on his website.
Our R&D Department have recently been working on a few upgrades to the THREEDY 3D Printer.
We now have new rubber (& THREEDY branded) heatbeds. Final testing is underway and they are working well. Quicker to heat up and better consistent heating. Give us a call if you want to know more about the technical details!
Tired of not knowing where we had left our SD cards, Richard has designed this handy THREEDY SD Card holder. If you would like to print your own, please ask us to send you the FREE stl file.
Our Cardiff branch are currently working on software updates…watch this space!
If you are lucky enough to have received some of our Tetrahedral Shapes and are looking to check your answers to the questions, you have come to the right place! Need more copies of the handout? Download a pdf here: Tetrahedral Geometry
What is the volume of the tetrahedron?
The whole cube with the corners on the 1,1,1 and -1,-1,-1 co-ordinates has a volume of 8 (2 x 2 x 2). The volume of the tetrahedron is 1/3 of this, ie 8/3
What is the volume of the triakis tetrahedron?
16/3 (this is exactly twice the volume of the tetrahedron)
How many cuts do you need to cut a rectangular block of cheese into three equal amounts using
a) a straight knife? 4
b) a cheese wire? 2
We hope you enjoyed the puzzles. If you would like any further explanation of the answers, please comment below.
The shapes were all printed by a THREEDY 3D Printer. If you would like to know more about THREEDY 3D printers, please browse our website. The printers are great for schools and colleges and we would be happy to visit you to demonstrate our printers, or deliver our 3D Printing workshop tailored to your students.
Please contact us to book a visit, or if you’d like any more information.
We met some brilliant and enthusiastic students at our THREEDY 3D Printing Workshop. As well as printing their own personalised key tags, the students had chance to attempt to solve some of Simon’s puzzles. They thought about what projects they could do using 3D printers.
More than 1000 pupils attended this STEM enrichment event over two days. Young Investigators Day (Years 3 to 8) and Secondary Day (Years 7 to 13).
Our THREEDY 3D Printing workshop was one of 58 different workshops available to the students and proved to be popular (to quote one girl “this was the best workshop we had seen”).
We are always keen to work with schools and to help encourage a new generation of 1st Class engineers. If you’d like to know more about what you could do with a THREEDY 3D Printer in your school, or to arrange a demonstration, please do not hesitate to contact us.
Here’s a link to the press release by STEM Team East, providing more details of the event
The vase was printed as a continuous spiral, demonstrating the superb sub-micron positional accuracy of the THREEDY in the Z-axis. Printing a vase which is over 15 cm tall using a sinlge thickness wall is a demanding test for any combination of printer and filament.
What will THREEDY 3D Printers be printing in 90 years time?
