The Mk4 will have additional optional accessories and new firmware when it is officially released at the Rocky Mountain RepRap Fest in April, 2024.

** International Customers: USPS Flat Rate Shipping starts at $55.15 for most customers... however, that may increase depending on your destination country.  We will contact you if additional funds are required for shipping. Customs fees, duties and taxes are the buyer's responsibility.

How it works

The 3D Chameleon works by taking advantage of the existing mechanical hardware on your 3D printer to automatically remove and reinsert the filaments when a color (or material) change is required.  By utilizing your existing electronics, we are able to use standard GCode commands to tell the 3D Chameleon which color to select.  

  • No modifications to your electronics or firmware
