Feature List for Big 3D Printer BLU-5

90%-Pre-assembled PLA Printer

90% Pre-assembled

BLU-5 developed parts into very few modules that could be completely set up with 6 screws within 30 minutes.


Auto-Leveling Design

BLU-5 is with integrated built-in 3DTouch kit which would test the distance between printing head and hotbed and compensate Z-axis deviation value.


300*300*400mm Printing Size

BLU-5 is with the largest printing space which allows users to print larger objects or more models with single printing. 


High Precision and Stability

BLU-5 3D uses double Z-axis with synchronous belt, silent driver with less viberation for quiet, smooth and precise printing.


X-axis & Y-axis Tensioners

Its wheel tensioners for X-axis and Y-axis enable get proper tension easily to avoid vibration and print shift for better printing results.


Adaptive Pulley

The patented adaptive pulley would automatically adjust and fit the aluminum profile to reduce vibration to maxim level.

Filaments Sensor

Filament Sensor & Resume Printing Function

It would send warning once filaments break or run out. If printing interrupted by power filure, it would resume printing once power recoved.

4.3 Inch Touch Control

4.3 inch LCD Display

4.3-inch touch control panel with quick and smooth responses to finger touch and provides multiple language options, easy and convenient to use.


Dual-drive Extruder

High quality 4401S dual wheel extruder with more strength to guarantee faster and smoother filaments feeding and retraction.


Control box skylight design

Patented removable control box cover design, easy to replace the stepper drive.


Simple wiring design

Use two CAT 7 Ethernet cables RJ45 to transmit data. Say goodbye to tedious wiring steps and messy cables. Reduce the safety hazards caused by exposed wiring harnesses.


Bed Leveling Screws

It is easy and convenient to give the hot bed platform stability to print without wobbling and make the model more smooth in surface.
