Introducing the newest addition in the Wanhao Duplicator 4 family, the brand new Wanhao Duplicator 4S! This dual extruder 3D printer is the latest update in the Duplicator 4 series. The good-value Wanhao 4S is really a wonderful device with an enclosed building chamber. It comes with all the benefits of Duplicator 4x. 3D print ABS without warping! Furthermore, you can build with support filament.

The main product features:

  • Very solid metal construction
  • Good-value manufacturing machine
  • Dual extruder allows support material
  • Closed construction building environment minimizes warping
  • 2 Free spools in the box
  • SimpliFy3D Compatible

Further information:

  • Very good-value for money
  • If you use this 3D printer and its software, your learning curve will be steep.

For you, it comes in a black steel exoframe, which makes it very stable and vibration safe. A heated build plate and a fully enclosed build area are characteristics of this good-value 3D printer. These features ensure accurate 3D prints and a stable temperature. 3D print with low warping and shrinking. The Duplicator 4S is equipped with the new MK10 Dual-Extruder set for dual manufacturing.

Use two different colors or one of the extruders with HIPS or PVA as support material. Other features include upgraded electronics and 1/16 micro-stepping motor control. If you want to unlock the full potential of the 3D printer we recommend that you buy SIMPLIFY 3D with this 3D printer. If you don’t want spend money ReplicatorG software is included.

The Duplicator 4S has our latest dedicated 1.75 mm filament extruder. This extruder was designed from scratch. It contains several custom manufactured parts. “We've learned a lot over our past extruder designs and incorporated a lot of those lessons here: that's why it's smaller, lighter, and faster to build”, says Wanhao.

Since its extruder is designed from the ground up for 1.75 mm filament. It's light-years ahead of past designs in small-filament reliability. Realize a much better layer alignment which results in nicer 3D prints and higher resolution, 100 microns. We've completely overhauled the drive system to give the optimum positioning accuracy. The entire system has been upgraded to sturdy 3/8″ diameter linear shafting. This is probably overkill, but you can trust that the axes will be sturdy.

We've also switched to self-aligning, sintered stainless steel bearings. These are very forgiving to DIY assembly and provide a nice, smooth motion on the steel shafts. We've completely replaced the Z axis with a stepper driver, cantilevered stage. Guided by two of the linear shafts, this eliminates any Z wobble and results in nicely aligned layers. Using a high-angle lead screw, we were able to increase the speed of the Z axis from 150mm/minute to 1,000mm/minute. This means the layer changes are almost completely imperceptible.

Connect the Wanhao 4S over USB and hit print button – the machine will calibrate itself and start 3D printing. The new electronics have been designed to make the process experience easier than ever. The Duplicator 4S connects to your computer via a standard USB cable thanks to a USB chip on the motherboard. We've also added full end stop support so that you never need to touch the XYZ axes ever again. When you hit print, the machine will automatically home itself, heat up, and begin 3D printing. All you must do is sit back and relax while your Duplicator 4s does all the work for you. Living in the future is awesome. Oh yeah, and the electronics are all inside, so you don't have wires dangling anywhere.

Or you can 3D print with SD card. Sometimes customer failed in manufacturing with computer USB link, due to the computer sleep or shut down automatically. For this reason, we developed SD card reader on a 3D printer. Awesome, all your production job can be executed from this small card. A 2 Gb card is sufficient for any 3D file and keep as a lot of data as you like. Simple and fast is our mission.
