As you know, Shapeways offers their SLS material (Strong & Flexible nylon) in a variety of finishes: plain white, dyed black, or in a white, polished finish. Next week, on October 17th, they will introduce a new option: polished & colored.
That's right, no longer do you have to choose between polished and black: you can have it both ways! Apparently the dyeing process has also been improved much ("more vibrant and consistent") and the penetration is deeper.
To celebrate, they're giving 10% off all colored SF products from October 17th until October 30th. The prices will also be changed permanently (to be lower). Regular WSF & BSF will stay the same, but polished will be up to 15% cheaper. Best of all, black polished will be only marginally (a fixed fee of $0.25) more expensive than white.
So why not check out a puzzle shop
