3T RPD Makes Christmas

14 December 2016 ...

In 2015 Sheffield University maths students produced a formula to mathematically calculate the ‘perfect’ amount of decoration that you need for your Christmas tree.

Their formula reads:

Ideal number of Baubles =  (√17 ÷20) x Tree Height (in cm)

The formula can give you the number of baubles that you need. By using Additive Manufacture (AM) short production runs from 3T RPD you can make your perfectly dressed tree unique. AM (additive manufacture) produced Christmas tree baubles will make your office or home tree really stand out from the rest.

It might be a little late for Christmas 2016, although we are still accepting orders until the 22nd December for delivery in Jan 2017, but the possibilities for AM production of Christmas baubles is almost endless. We have made a short video, complete with cheesy Christmas music, of some of the designs that we designed for 3d printed Christmas baubles. We hope that it inspires you to try and design your own short production run of the optimum number of Christmas baubles for next year.

So how many AM production baubles are the right number of baubles for your Christmas tree?

According to the formula, you need the following numbers of baubles:

Tree Height (in cm) Height (in feet and inches) Number of Baubles
150 5’ 0” 31
160 5’ 4” 33
180 6’ 0” 37
190 6’ 4” 39
200 6’ 8” 41


Remember that this is only a guide, we are sure that your tree will look fantastic in the living room or office, no matter how many baubles you have on it.

Don’t forget that, we can build your parts over the Christmas/New Year break. Our machines will be running every day throughout this period, however order despatch will depend upon courier service availability.

Please email your requirements and data to by 5pm on Thursday 22nd December to ensure we build your parts during the festive period for delivery in Jan 2017.
