Copperhead™ Hotend: Eliminate Heat Creep

What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

Have you ever experienced resolution loss and jamming with your 3D printer? Slice Engineering®, the makers of Mosquito™ hotend, is excited to introduce the Copperhead™. The Copperhead™ is a low-cost, open-source hotend option that can handle the heat — heat creep, that is. Replace your factory model hotend with the Copperhead™, to upgrade your 3D printer’s performance and reduce jamming, giving you a smooth print every time.

Review from John Mulac (3D Printing World)

What is Heat Creep?

Unlike most materials, plastics don’t have a clean transition from solid to liquid during melting. As filament moves through the hotend, it heats up and reaches the material’s glass transition temperature (Tg), entering a semi-solid, semi-liquid, “gooey” state. While in this state, the plastic responds to applied forces like a wet noodle, causing undesirable print effects like reduction in resolution, blobbing and jamming. An efficient heat break narrows the physical distance during which the plastic is at it’s Tg, and thus improves 3D printer performance. The Bimetallic Heat Break™ from Slice Engineering® is the only heat break designed through the use of thermal imaging to optimize heat transfer.

About Slice Engineering®

The Slice team is not new to the 3D printing scene. Slice started out with the desire to build a better hotend, something we succeeded in doing with the launch of the Mosquito™ in March 2018. The core concept behind the Mosquito™ was to use fundamental engineering principles to create the most technologically advanced, robust, and thermally efficient hotend available.

Based on your feedback and the lessons learned from over a year of successfully building the Mosquito™ hotends, we have decided to take the core technology of the Mosquito™ - the high efficiency, heat creep eliminating, Bimetallic Heat Break™ - and apply it to a less expensive, open-source offering: Copperhead™.

For more information on our engineering grade components for 3D printers, please visit sliceengineering.com 

Enjoy endless possibilities when your creativity isn’t limited by heat creep and printing jams. 

Print what you want, when you want it with The Copperhead™ hotend. The world’s first open-source, low-cost hotend designed through the use of extensive thermal testing to optimize heat transfer and eliminate heat creep. We want you to get the most out of your 3D Printer, but we need your support. Please back Slice Engineering® today, so you can effortlessly print tomorrow. 

Risks and challenges

The FFF 3D printing market is still very niche, so we will need lots of community support to bring this Kickstarter to life.

We’ve done our very best to minimize product risks by building fully functional prototypes and performing extensive testing both in house at Slice Engineering®, and with some of our talented Beta testers.

Operational risks include perfecting mass-production assembly of the Bimetallic Heat Break™ for the Copperhead™ application and ensuring things go smoothly with coatings suppliers.

There are also the very real existential risks related to knock-offs. Every time someone buys a knock-off product they strike a blow to innovation, independent creative thought, and small scale manufacturing.
