Larger Build Volume – Unleash Your Creativity

As 3D printing continues to expand, the demand for larger print sizes grows. The LK10 Plus offers a 320×320×400 mm build volume, allowing for large models without splitting or assembling parts.

This larger build volume is ideal for:

•  Complex architectural models 

•  Life-size character sculptures 

•  Automotive prototypes 

•  Functional engineering parts 

•  Large-scale art projects 

For users searching for a large desktop 3D printer, the LK10 Plus significantly reduces post-processing and assembly time while improving workflow efficiency.

Klipper High-Speed Board – Faster Printing Without Compromise

The LK10 Plus features a high-speed control board compatible with Klipper firmware, delivering advanced motion algorithms and smooth high-speed printing:

• Max print speed: 500 mm/s 

• Max acceleration: 10,000 mm/s² 

With Klipper, printing large and complex models is faster while maintaining stability. The board includes 8GB storage, supporting large print files, and motion sensors on the X and Y axes automatically calibrate parameters for consistent performance during high-speed printing.

High-Flow Direct-Drive Extruder – Maximize Material Potential

The LK10 series uses a high-flow direct-drive extruder with a 9.5:1 high-reduction gear ratio and HRC60+ hardened gears. This design ensures:

•  Strong, stable filament extrusion 

•  Smooth printing at high speeds 

•  Excellent compatibility with flexible filaments like TPU 

The near-end direct-drive reduces filament path length, lowering resistance and retraction delays, providing reliable extrusion for large, high-speed prints and versatile material options.

Eddy-Current Auto Bed Leveling – Perfect First Layers Every Time

The LK10 series features eddy-current auto bed leveling, a non-contact system that precisely scans the bed surface for height variations. Unlike traditional point-based leveling, it performs linear scans for higher accuracy and faster setup. During printing, real-time Z-axis compensation ensures even layers, reducing warping and clogs.

This feature is especially beneficial for beginners looking for an easy-to-use 3D printer with automatic leveling.

Smart Automation – Less Intervention, More Productivity

The LK10 series includes intelligent automation features:

• Filament run-out detection: Pauses prints automatically when filament runs out 

• Semi-automatic belt tensioning: Maintains optimal belt tension without manual adjustments 

These features enhance reliability and ease of use, letting you focus on creating rather than troubleshooting.

Copper-Titanium Bi-Metal Heatbreak – Optimized Thermal Management

The Copper-Titanium bi-metal heatbreak combines:

• Titanium section: High strength, low thermal conductivity to prevent premature filament softening 

• Copper section: Excellent thermal conduction for efficient heat dissipation 

This design ensures stable extrusion and precise thermal control, reducing clogging and maintaining consistent print quality for long-duration prints.

Additional Upgrades for Better User Experience

In addition to core upgrades, the LK10 series FDM 3D printer includes several improvements designed to enhance usability and print quality.

• 5015 High-Airflow Cooling Fan

The 5015 cooling fan provides stronger airflow for faster model cooling, helping improve overhang performance and fine detail accuracy.

• Optimized PEI Build Plate

The PEI build plate offers excellent adhesion and helps reduce warping, ensuring a stable first layer and more reliable prints.

• 4.3-Inch Full-Color Touchscreen

A 4.3-inch full-color touchscreen provides an intuitive interface for adjusting settings and monitoring print status in real time.

Unboxing and First Impressions

The LK10 series desktop FDM 3D printer arrives in well-protected packaging with foam inserts that secure each component during shipping. The printer comes partially pre-assembled, allowing users to complete setup with just a few simple steps.

Inside the box are the gantry frame, base unit, 4.3-inch touchscreen, filament holder, power cable, sample filament, tool kit, USB drive, and installation screws. The instruction manual provides clear illustrations, making the setup process easy even for first-time FDM 3D printer users.

Once powered on, the touchscreen interface is responsive and easy to navigate. The eddy current auto bed leveling system automatically scans the build plate before printing, helping ensure a stable first layer. Combined with the high-flow direct-drive extruder and a 320 × 320 × 400 mm build volume, the LK10 series delivers a smooth and beginner-friendly first printing experience.

The LONGER ePrint UV-texture printer series has recently been featured on All3DP, one of the industry’s most reputable platforms for 3D printing and digital fabrication.
The article highlights ePrint as a major breakthrough in personal and studio-grade UV printing—thanks to its dual-printhead architecture, true 60 mm raised texture technology, and a fully AI-driven design-to-print workflow.

https://all3dp.com/4/longer-releases-eprint-the-worlds-first-dual-printhead-3d-texture-personal-uv-printer/

A Breakthrough in Personal UV Texture Printing

All3DP describes the LONGER ePrint as the world’s first personal-grade dual-head UV printer, engineered for creators and small businesses seeking industrial-quality texture, speed, and versatility.
Its dual-printhead, 12-channel configuration enables rich color output, rapid material layering, and seamless multi-pass workflows. This results in:

• Up to six times faster production

• Stronger, sharper tactile layering

• More flexible multicolor and special-effect printing

The ePrint brings professional UV printing capability into a compact, desktop-size form factor.

True 60 mm Raised Texture — Bringing Tactile Depth to Desktop UV Printing

A major highlight from the All3DP review is the ePrint’s up to 60 mm raised-texture performance, far beyond the slight bump typically associated with UV layering.
Through precise UV-curing and layer-stacking algorithms, the system offers:

• Sculptural, touchable depth

• Consistent layering from edge to edge

• Reliable performance even during long production runs

This combination of full-color UV graphics and true 3D tactile relief is rare at any price point—let alone in a desktop unit.

300+ Material Support for Creative and Commercial Use

The ePrint series is compatible with a wide range of substrates, including wood, metal, acrylic, glass, ceramics, plastic, canvas, leather, stone, and even curved or uneven objects.
With a 10 mm high-gap jetting design, the printer maintains accuracy even on surfaces with 2–10 mm height differences, making it ideal for:

• Bottles and cylindrical packaging

• Embossed and textured surfaces

• Curved consumer products

• Multi-layered objects and specialty merchandise

This flexibility opens the door to diverse applications, from custom gifts to small-batch commercial production.

AI-Powered Workflow Designed for Efficiency

All3DP also highlights the system’s integrated AI engine, which streamlines the entire creative process.
The AI suite includes:

• Image generation and style variation

• Background removal and template autofill

• Sketch enhancement to full illustrations

• Dual-laser material height sensing

• Auto focus and real-time print error detection

• One-click product mockups for marketing

• Batch auto-fill for mass production

This significantly reduces design time and minimizes print failures.

Automatic Printhead Maintenance for Long-Term Stability

To address common UV printing issues such as white-ink clogging, the ePrint integrates a closed-loop cleaning system with continuous white-ink circulation.
This automated maintenance ensures consistent ink flow, reliable long-run output, and minimal downtime—especially important for workshops and businesses.

Open-Ink Architecture for Maximum Flexibility

The ePrint supports both LONGER’s original high-precision UV inks and a wide range of third-party options.
This open-ink design allows users to optimize for:

• High-accuracy color reproduction

• Cost-effective production

• Low-migration inks for packaging applications

Product Line Overview

LONGER ePrint

• Dual printheads, 12 channels

• Up to 4 m²/h (4-pass mode)

• 200 ml × 12 high-capacity cartridges

• Compatible with rotary, conveyor belt, and roll-to-roll systems
