What Bondtech does

Bondtech AB is a Swedish privately-held designer and manufacturer of filament feeding subsystems for desktop FDM 3D printers, headquartered in Värnamo and operating as a subsidiary of the Ernströmgruppen conglomerate. The company develops and sells upgrade kits, extruders, hotends, and nozzles — including its proprietary LGX (Large Gears eXtruder), DDX (Direct Drive eXtruder), BMG (Bondtech Mini Geared), and CHT (Core Heating Technology) product lines — distributed globally through direct e-commerce, authorized resellers, and OEM partner integrations across more than 17 printer platforms (Creality, Prusa, Bambu Lab, Voron, Ultimaker, Anycubic, and others).

Bondtech's technical differentiation is rooted in proprietary dual-drive gear architecture (introduced 2015, with subsequent generations including Mini Dual Drive in 2017 and LGX in 2021) and CHT nozzle inlet geometry, the latter claimed in company white papers to deliver a 63.1% average increase in volumetric flow rate versus standard nozzles. The portfolio is extended through co-marketed hotends from technology partner Slice Engineering and a 2025 expansion into multi-tool printing via the INDX Automatic Tool Changer, marking the firm's first architectural step beyond extrusion-only subsystems.

Bondtech monetizes exclusively through hardware sales (supplemented by technical support, firmware updates, and setup guides), pricing individual products between roughly $13 (small mounts/accessories) and $485+ (LGX ACE printheads), with multi-currency DTC checkout (EUR/USD/SEK), EU VAT handling, FedEx and PostNord logistics, and payment integration via PayPal, Stripe, and Klarna. End customers span individual hobbyists, professional users, and manufacturing users, while OEMs purchase via a formal embedded partnership program. Revenue is not publicly disclosed and the firm operates without external venture funding, with company size implied at 11–50 employees.

Core offering

Bondtech designs, develops and manufactures precision filament feeding systems for desktop FDM 3D printers. Its product range includes dual-drive extruders (LGX, LGX PRO, DDX), high-flow hotends and printheads, CHT brass and BiMetal nozzles, and a broad catalogue of printer-specific upgrade kits compatible with 17+ brands, sold directly to end users and through OEM partner integration.

Product overview

Bondtech is a Swedish company (Bondtech AB) specializing in precision filament feeding technology for FDM 3D printers. The product portfolio centers on their core extruder technology including the LGX Large Gears eXtruder and DDX Direct Drive eXtruder systems, complemented by their signature Core Heating Technology (CHT) nozzles. Products are organized around four main categories: Upgrade Kits for 17+ printer brands (Creality, Prusa, Bambu Lab, Voron, etc.), Extruders (LGX, LGX PRO, DDX), Hotends (Mosquito, Copperhead, Magnum Plus by Slice Engineering), and Nozzles (Bondtech CHT brass and BiMetal). The company also offers the INDX Automatic Tool Changer for multi-tool applications and printheads combining their extruders with hotends from partner Slice Engineering. The ecosystem is designed for modularity, allowing users to upgrade incrementally—for example, the DDX follows a phased upgrade path (PH1-PH4) for Creality printers.
