3D printing works best when your machine runs smoothly and consistently. Small hardware upgrades can make a noticeable difference in print quality, speed, and reliability.
That is where BIQU accessories come into play. These components help you improve common problem areas such as extrusion accuracy, bed leveling, and printer control.
BIQU and BIGTREETECH have gained attention among makers for producing upgrade parts that work with popular printers like the Ender-3, CR-10, and Voron systems.
Many enthusiasts choose these accessories because installation is straightforward and firmware support works well with Marlin or Klipper.
Discussions across maker forums and communities such as Reddit and the Voron Discord frequently mention BIQU upgrades as cost-effective improvements for hobby and small workshop printers.
According to Statista, the global 3D printing market continues expanding rapidly and is projected to exceed $50 billion within the next few years, which explains the rising demand for reliable upgrade components.
If your printer struggles with inconsistent extrusion, uneven first layers, or noisy motors, the right accessory can solve those issues quickly.
BIQU Accessories That Help You Upgrade Your 3D Printer Performance
BIQU offers a wide range of upgrade components designed for both beginners and experienced makers. These parts typically focus on three areas:
- extrusion performance
- print accuracy
- printer control and monitoring
Many makers upgrade these components gradually instead of replacing the entire printer. A well-planned upgrade path often improves results while keeping costs manageable.
Below is a quick overview of several popular BIQU components and their typical US pricing from the official BIQU store.
| Accessory | Purpose | Typical US Price |
| BIQU H2 Direct Drive Extruder | Improves filament control | $65 – $109 |
| H2 V2S Lite Extruder | Lightweight high-speed extrusion | $84 – $95 |
| MicroProbe V2.0 | Automatic bed leveling | $16.99 – $29.99 |
| SKR Mini E3 V3.0 | 32-bit control board upgrade | $25 – $45 |
| TFT35 Display | Touchscreen interface | $35 – $55 |
| BTT Smart Filament Sensor V2.0 | Detects jams and runout | $15.99 – $22.99 |
| Flexible PEI Build Plate | Improved adhesion | $9 – $25 |
These upgrades target the most common causes of failed prints.
BIQU H2 Direct Drive Extruder
The BIQU H2 Direct Drive Extruder remains one of the most discussed upgrades in the maker community. The design combines the extruder and hot end into a compact unit.
Typical US price: $65–$109
Key specifications:
- weight around 219 grams
- 7:1 gear ratio for stronger extrusion force
- supports 1.75 mm filament
- maximum temperature around 260°C
A direct-drive design shortens the distance between drive gears and the nozzle. This helps control flexible materials such as TPU and reduces stringing during retractions.
Case discussions on printing forums often highlight smoother extrusion when switching from a Bowden setup to this system. Users printing small mechanical parts often report improved dimensional accuracy.
A potential limitation exists for very high-speed printing setups because the added carriage weight may slightly affect acceleration.
H2 V2S Lite Extruder for Lightweight Printing
For printers tuned for speed, the H2 V2S Lite Extruder offers a lighter design.
Typical US price: $84–$95
The extruder weighs about 175 grams, which reduces moving mass on the print head. Lower weight helps maintain accuracy during fast movements.
Key features include:
- skeleton frame structure
- improved cooling design
- MK8 nozzle compatibility
- flow rate up to 45 mm³/s
This upgrade suits printers configured with Klipper firmware where speed tuning plays a large role in performance.
Some users mention that installation requires careful wiring management, so beginners may spend extra time during setup.
MicroProbe V2.0 Auto Bed Leveling Sensor
Uneven bed surfaces create many first-layer problems. The BIQU MicroProbe V2.0 solves that issue through automatic probing.
Typical US price: $16.99–$29.99
- Important specifications:
- accuracy around ±0.003 mm
- compact 24 × 21 mm sensor body
- weight about 6 grams
- compatible with Marlin and Klipper firmware
The probe measures several points across the build plate. Firmware then compensates for small variations.
This process improves first layer adhesion and reduces failed prints caused by manual leveling mistakes.
Many hobbyists report noticeable improvements when switching from manual leveling to automated probing.
BIGTREETECH SKR Mini E3 V3.0 Control Board
Older printers often run on outdated 8-bit motherboards. The SKR Mini E3 V3.0 upgrades processing power and motor control.
Typical US price: $25–$45
Key features:
- 32-bit ARM Cortex-M0+ processor
- support for TMC2209 silent stepper drivers
- compatibility with 12V and 24V systems
- micro-USB and SD card firmware updates
Many Ender-3 users install this board to reduce motor noise and gain more advanced firmware features.
Community discussions frequently mention smoother motion control after switching to this board.
BIGTREETECH TFT35 Touchscreen Display
User interfaces matter when interacting with a printer daily. The TFT35 Touchscreen Display modernizes printer controls.
Typical US price: $35–$55
Features include:
- optional WiFi module compatibility
- 3.5-inch 480 × 320 touchscreen
- dual interface modes
- micro SD support
Users can switch between a touchscreen interface and a traditional LCD menu. This flexibility helps those who prefer the classic Marlin control style.
BTT Smart Filament Sensor V2.0
Filament issues often ruin long prints. The Smart Filament Sensor V2.0 monitors filament movement during printing.
Typical US price: $15.99–$22.99
The sensor detects:
- filament runout
- extrusion jams
- lack of filament movement
When a problem occurs, the printer pauses automatically. This protects long print jobs and prevents wasted filament.
Print farms often rely on sensors like this to reduce failed production runs.
BIQU Flexible PEI Build Plate
Bed adhesion directly affects print success. The BIQU Flexible PEI Build Plate improves both adhesion and print removal.
Typical US price: $9–$25
Available sizes:
- 220 × 220 mm
- 235 × 235 mm
- 310 × 310 mm
The surface uses textured PEI coating on spring steel. After printing, the plate flexes slightly so parts pop off easily.
This feature helps prevent damage to both prints and the build surface.
BIQU Filament Materials
BIQU also manufactures several filament types for everyday printing.
Typical US price: $25–$35 per 1kg spool
Available materials include:
| Material | Best Use |
| PLA | General prints and prototypes |
| PETG | Strong mechanical parts |
| ABS | Heat-resistant components |
| TPU | Flexible designs |
Filament arrives vacuum sealed to prevent moisture absorption during storage.
Consistent diameter helps maintain smooth extrusion and stable layer bonding.
Recommended Upgrade Path for Most Printers
A simple upgrade plan helps improve results without spending too much at once.
Entry upgrades
