Minipro 6.85 May 2026

Why 6.85 inches? The 180mm cube is a strategic size. It is large enough to print a full-sized helmet in pieces, a drone frame, or a functional bracket, yet small enough that the printer fits on a standard IKEA Lack table (which measures 22" x 22").

Many users report that 70% of their prints fit within 150mm, making the MiniPro 6.85 a space-efficient choice for dorm rooms, offices, or small workshops. The 6.85" diagonal measurement also means you can print objects that would just barely exceed the Prusa Mini’s 180mm round bed.

The MiniPro 6.85 comes with a branded version of Cura (or PrusaSlicer, depending on the batch). However, the printer uses standard G-code, so it works with: minipro 6.85

Wi-Fi Printing: The optional Wi-Fi module is worth the extra $15. Using the proprietary "MiniPro Remote" app, you can upload files directly and monitor print progress via a basic time-lapse feature.

When you first lay eyes on the MiniPro 6.85 box, you notice the thoughtful packaging. The printer arrives partially assembled—about 85% complete. Unlike older kits that require you to build an entire frame from extrusions, the MiniPro 6.85 requires only four bolts to attach the gantry to the base, plus plugging in the ribbon cables.

In the box, you will find:

First impressions are dominated by the machine’s rigidity. The frame uses 2020 aluminum extrusions with reinforced corners, eliminating the wobble common in sub-$200 printers. First impressions are dominated by the machine’s rigidity

6.85 (2025-02-17)
- Add: 23 new IC definitions
- Fix: USB timeout on large SPI reads (>16MB)
- Fix: Linux permission issue (non-root)
- Change: Improved GAL fuse map parser
- Change: CLI progress output now quieter in scripts (--quiet)
- Security: Fixed potential buffer overflow in Intel HEX parser

Let’s get into the granular details. The MiniPro 6.85 is defined by these specs:

| Feature | Specification | | :--- | :--- | | Print Technology | FDM (Fused Deposition Modeling) | | Build Volume | 180 x 180 x 180 mm (6.85" cubed) | | Chassis Material | Aluminum extrusion + injection molded ABS shell | | Print Surface | Magnetic flex plate + PEI-coated spring steel | | Extruder Type | Direct Drive (Dual-gear metal) | | Nozzle Diameter | 0.4 mm (interchangeable) | | Max Nozzle Temp | 260°C | | Max Bed Temp | 100°C | | Supported Filaments | PLA, PETG, TPU, ABS (enclosure recommended for ABS) | | Layer Resolution | 0.05 mm to 0.35 mm | | Print Speed | 30–120 mm/s (recommended: 60 mm/s) | | Bed Leveling | Automatic (Inductive probe + strain gauge) | | Connectivity | USB-C, MicroSD Card, Wi-Fi (optional dongle) | | Display | 4.3-inch Color Touchscreen | | Power Supply | 24V / 150W (Mean Well style) | | Noise Level | < 45 dB (Silent stepper drivers) | | Dimensions (printer) | 370 x 340 x 400 mm |

The standout feature here is the direct drive extruder. In this price range, most competitors use a Bowden tube setup (where the motor is on the frame, pushing filament through a long tube). The MiniPro 6.85’s direct drive places the motor directly above the hotend. This drastically reduces retraction issues and allows you to print flexible filaments like TPU effortlessly.
