WHAT PEOPLE SAY

Florian Gehrke (All3DP)

The Longer LK4 Pro is a leggy new budget 3D printer with a fantastic interface.

Participating in a new and silly tradition of designating mildly upgraded 3D printers as “Pro”, the Longer LK4 Pro is, unsurprisingly, an evolution of the LK4 that came before it.

David

This is a remarkable printer for someone that's looking for a low-cost, entry-level machine with plenty of room to grow. Longer provides full access to the source-code (a huge plus if you want to make your own modifications) and designs. There's also a large community that can help with troubleshooting and mods. Support from the seller (on Amazon) has been top-notch. I'm really impressed with this machine.

Michael Bird

The Longer LK4 Pro is an excellent beginner printer. At under £180, it is a contender for the Ender 3. With the addition of the touchscreen and its TMC stepper drivers, it’s a great buy!
