Markforged, a 3D printer manufacturer based in Boston, has just announced two new models — the X3 and the X5. Both of these printers are designed to create carbon fiber-infused objects using a standard filament printing system and both can produce items that can replace or are stronger than steel objects.

Both printers have auto-leveling and scanning systems to ensure each printed object is exactly like every other. Further, the printers use Markforged’s special thermoplastic fiber filament, while the X5 can add a “strand of continuous fiberglass” to create objects “19X stronger and 10X stiffer than traditional plastics.” This means you can print both usable parts and usable tools using the same machine and, thanks to the fiberglass weave, you can ensure that the piece won’t snap on use. For example, one customer printed a custom valve wrench in 10 minutes using one of these printers.

Now for the bad news. The X3 costs a mere $36,990, while the X5 costs $49,900. These are aimed at what Markforged calls “local manufacturers.” Luckily you’re not stuck with the printer if you outgrow it. The X3 can easily be upgraded to work with X5’s filament and both are aimed at manufacturing shops that need to produce finished products on the fly.

“Customers can now, with ease, print same-day parts that optimize strength and affordability for their specific needs,” said CEO Greg Mark.

These printers are part of Markforged’s effort at creating a real “teleporter.” Thanks to the complex scanning and measurement systems built into these units, users can receive a 3D printer model and print it to exacting specifications. The system also has a failsafe mode that restarts at any time as the laser scanner can check to see exactly where the print stopped. The company is also hard at work on some impressive metal printing technologies that turn out parts that are usable in complex machines.
