What is G4G?

Martin Gardner

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

The focus is on sharing interesting things in the related fields of:


  • mathematics,
  • science,
  • puzzles
  • & magic

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 objectsoli bottles
  • easy way to understand Tower of Hanoi
  • how the Infinity puzzle was solved
  • automata
  • extreme puzzles
  • magic

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.


Back To School

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.

3D Printing Impossible Objects

img9When 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. puzzlegrill

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.


Ambiguous Cylinders on the West Highland Way

Simon and his family enjoyed their summer holiday walking the West Highland Way – yes, all 96 miles of it. IMG_20160823_133906IMG_20160831_112800Greetings 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.


THREEDY Developments

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. IMG_0084Final 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!

IMG_0083Tired 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. IMG_20160811_120656750

Our Cardiff branch are currently working on software updates…watch this space!

Interesting Variants on Tetrahedral Geometry

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.

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.IMG_20160614_131849IMG_20160614_132154

The Digital Revolution: Every primary school should have THREEDY 3D Printers

Prepare children for the impact of the digital revolution (the “fourth industrial revolution”)

In The Digital Revolution, published by the Edge Foundation (9th May 2016) Lord Kenneth Baker, former education secretary and Chair of the Edge Foundation,  calls for radical action to prepare children for the the impact of the next industrial revolution.

ImageGen.ashxThe full report is available for download here

This report on the  Impact of the Fourth Industrial Revolution on employment and education, was prompted by the Bank of England’s prediction that up to 15 million jobs are at risk of automation across the UK economy.

Lord Baker says ‘The economy is changing at an unprecedented pace. Every day, jobs are being lost in professions we used to regard as careers for life. Artificial intelligence, robots, 3D printing and driverless vehicles will impact on sectors as varied as the legal profession, transport and construction.’

From the report:

Future applications are limited only by our imagination, which makes it essential for children to learn to use 3D design and technology from primary level onwards.

The nature of making and doing must, of course, keep pace with the technological revolution: every primary school should have 3D printers, and computer science should be as common in schools as modern foreign languages because programming skills will be vital for many people in the future.

Lord Baker has set out an eight-point education plan which responds to the digital revolution, which includes providing 3D printers and design software for all primary schools.

Would you like to have reliable, fully supported THREEDY 3D printers in your school?

We are a British company supporting schools. We want 1st class engineers in this country and will help you to make your students fine engineers.  We will be happy to talk to you about how THREEDY 3D printers are being used in schools & colleges and answer any questions you may have about 3D printing and how it could benefit your students.

Please contact us to arrange a demonstration.
