The first to receive an update is the da Vinci 3D Pen, which initially debuted in 2016. The new version is called 3D Pen Cool, and as you might have gleaned from the name, it's meant to be safer than previous versions, thanks to some temperature modifications that make the items cooler to the touch. That alone should make it a worthier competitor to its main rival, the 3Doodler pen.

Like the previous da Vinci 3D Pen, the 3D Pen Cool extrudes PLA plastic filament in the air to create a 3D sculpture. It has a two-color LED indicator (red and green) plus a two-action control button for loading and unloading. It's powered via a micro-USB cable, which XYZPrinting says is lighter than a traditional power cord.

Next up is the da Vinci Nano, which was teased at last year's CES but did not ultimately make it to retail. Since that time, however, XYZPrinting has refined the Nano to include a new software package called the XYZ app maker, which lets users 3D print straight from their tablets (and eventually their phones). It's as compact as ever at 4.7 inches squared, but it's now available in white instead of red. And yes, XYZPrinting hopes the Nano will be available for real this time around.

Last but not least is the da Vinci color AiO, which is aimed at small businesses rather than consumers. It combines both printing and scanning capabilities in full color, thanks to the combination of inkjet and 3D printing tech that imbues the PLA filament with ink droplets of varying colors.

The da Vinci 3D Pen Cool will retail for $45, the Nano will cost $229 and the business-focused AiO will be available for close to $4,000. The company says they'll all be available early this year.
