The Knotty Celt

Ancient tradition meets modern technology for impossible creations.

The Knotty Celt was established by Andrew Brownrigg.  He combined his passion for the beauty and complexity of Celtic knots with his adept 3D modelling skills to create knots with deep meaning.  With the innovation of the 3D printing industry, he was able to realize his knot patterns in physical form.
Each piece is made by 3D printing a tangible model in casters' wax.  The wax model is then used to make a plaster mold.  Next, the plaster mold is used to cast the piece from molten metal.  This technique allows for some very complex knot patterns to be realized in the physical world.  Having been cast as a single piece, also means the knots are truly infinite loops, with no seams - an otherwise impossible feat.

I own two of these pieces (the Celtic Cross and Heart knots). They're intricately designed and I've had many comments on how beautiful they are! I love that there are many options for different metals.... Would make a great gift!
