We’re going to put a few notes out following a build of the Fisher Delta Beta 3D printer from RepRapPro. Sadly they have announced recently they are withdrawing from the 3D printer market, see https://reprappro.com/ “to focus on other activities”, which is a bitter blow from a company with Adrian Bowyer as one of the directors. On the plus side the open source designs and instructions are still available form the site.
The wee beasty looks like this and was available as a self build kit:-
Is it the wonder of watching 3D print progress? The fascination of seeing each layer build one upon one the other as a design goes from thought to reality. There is nothing quite like watching a design came to life: Layer by layer slowly building up upon itself with the printhead leaping from one section to another. As it grows it leaves areas filled with a honeycomb pattern inside, soon to be hidden and only glimpsed in the making . It is as mesmerising to watch all this unfold as it can be to stare into the flicker of the candlelight or a hearth fire.
But what is else is there once the novelty has worn off?
I can clearly remember on a summers day during one of those seemingly idle summer holidays wondering what it might be like to have my own mini world to play with. At the time this was an unreachable goal. Yet the idea was captivating And drew Me towards the imaginary worlds of science fiction.
As an adult is there a more tangible way in which we can act on these kind of creative impulses? I believe there is.
By designing your own objects you are free to think in three dimensions and to experiment with what is possible to create.
In doing so the gives you a tremendous feeling of freedom to do whatever takes your fancy to extend here, shrink there, add and subtract gives you a feeling of empowerment and total control over the design in front of you. It can be intoxicating. You could design a totally preposterous multi turreted castle with drawbridge upside out or inside out for that matter. You decide what is good without even the restriction of gravity to hold you back. Of course you may not create a design that is considered useful or practical by others but that may not be the point. It is your design. You decide what is and what will go where. It is also possible to follow utilitarian rules and generate your design to close engineering requirements which follow the best design principles for stable and consistent shape. It is entirely up to you what you do and whether you meet any external requirements. You are also free to design an unprintable design!
