Makers reaching for $40,000 stretch goal

If you blinked, you probably missed it.

The Kickstarter campaign to raise $17,500 for B3 Innovations' Pico all metal hot-end took all of 48 hours to reach its goal of $17,500.

"We are humbled and ecstatic at the support and response for Pico in such a short timeframe," B3 co-founder Michael Koury said.

The Pico's threads are tapered to prevent leakage, as is seen in the gas industry. It can be run at an operating temperature of up to 300° Celsius (572° Fahrenheit), limited by the thermistor. The upper half has a built-in heat sink, a span of cooling fins that increase surface area, dissipating heat into the surrounding air.  This helps prevent jamming by reducing temperature migration upwards. Tests indicate that when printing at 260° Celsius (500° Fahrenheit) the Pico's top threads are less than 46° Celsius (115° Fahrenheit).

B3 cofounders Koury and William Moujaes are now shooting for a $40,000 stretch goal to create a Pico that prints up to 500° Celsius (932° Fahrenheit). With 22 days left, they are $26,124 from 211 backers.

A donation of $99 gets you a Pico with nozzle size of your choice.

A hot end that prints up to 500° Celsius would be the first of its kind. It would be invaluable when working with some polycarbonates already on the market, in addition to printing materials that are on the horizon.
