NZ Companies Launch World’s First Wool-Based Colour for 3D Printing Filament
A collaboration between two New Zealand companies will see wool used as a renewable colour source for 3D printing.
That’s how Central Hawkes Bay wool buyer Philippa Wright is describing the present season, which she says is due almost entirely to the weather.
Wright told Rural News, from her base in Waipukurau, that the rain and heat in November and December completely changed the quality of the wool. And it delayed shearing by about a month, which is having serious flow-on effects.
“The wool we are now receiving is longer, yellower and poorer quality, simply because of the environment we have had,” she explained.
“The price was down anyway and is pretty much on a par with last year, but the quality of the wool is making it much more difficult. Normally in Central Hawkes Bay we have strong, clean, well grown wool. But this year, because of the poorer quality of the wool, it’s harder to sell.”
Wright says wool shorn in the area is normally 100-150mm in length, but this year it is 120-170mm in length. While some of that may be due to late shearing, the weather has played a role in the whole equation.
“This year wool is harder to sell because as soon as you get extra-long wool you will generally get the colour and the faults,” Wright says. “Most of the wool goes for carpet, but once upon a time 80% of our wool in this area went to carpet; now it’s more like 15%.”
According to Wright, NZ relies heavily on China finding new ways to use that type of wool. A lot of research is going into finding new uses for wool, but the challenge is finding manufacturers that will take the bulk of our wool.
“We now have too much of a type that isn’t particularly easy to use.” she says.
