GeoKnight DK3D Digital Knight Double-Wide Mug Press – 10″ Sublimation Mug Heat Press for Full Wrap Printing

Double the Output

The 10″ heater presses two standard matching mugs at once — cutting cycle time per mug roughly in half on big orders and fundraiser runs.

Goes Beyond Mugs

Wrap extra-tall items — 20 oz and 30 oz tumblers, water bottles, thermoses and travel mugs — with prints up to a full 10″ high, handle-to-handle.

SuperCoil-Microwinding™ Heat

Tightly wound heater elements run the full length of the platen for even heat and fast recovery — and the press holds your set temperature instead of idling low between presses.

Digital Control That Repeats

Digital temperature, automatic timer, programmable presets, cycle counter and end-of-cycle alarms — ±2°F accuracy for consistent results across long runs and multiple operators.

Built for Non-Stop Use

Thick solid-steel welded frame and die-cast clamp handle production all day. The clamp adjusts to very heavy pressure for full-bleed transfers, and a soft liner compensates for uneven mugs.

Industry-Leading Warranty

Patented stainless-steel mug-band heater — not a short-lived silicone blanket — backed by a 3-Year / 3,000-mug warranty and FREE lifetime tech support.

High-Volume Mug Runs

Two mugs per cycle makes short work of fundraiser, wedding, corporate and team orders — the same high-margin add-on, at higher throughput.

Tumblers & Water Bottles

Tap into the booming tumbler and bottle market — 20/30 oz tumblers, water bottles and thermoses up to 10″ tall, full wrap.

Works With Your Workflow

Compatible with dye-sublimation transfers, heat-transfer materials and Cricut Infusible Ink — pair with a Sawgrass printer and sublimation paper for a turnkey setup.
