Monopoly Mini V2: A Basic Guide to 3D Printing of Your Desktop
introduce
The rise of affordable desktop 3D printers like the Monprice Select Mini V2 has revolutionized the prototype, empowering designers, engineers and amateurs. As a senior fast prototyping manufacturer with cutting-edge SLM metal printers and postprocessing expertise, Greatlight understands the balance between accessibility and precision – which is why the Mini V2 chosen remains a fascinating gateway. Although professional-grade projects require our industrial capabilities, this compact workhorse offers incredible value for iterative design and low-capacity PLA/PETG models. Let’s analyze why this printer has become a cult classic for the manufacturer.
What sets the mini V2 for monomer selection?
As an upgrade to the original Mini V1, the V2 retains a minimalist design, but raises early questions, providing:
- Compact build volume: 120mm x 120mm x 120mm – Ideal for small prototypes, jewelry or mechanical parts.
- Heating bed and silent driver: Improved warping prevention and quieter operation using Trinamic drivers.
- Community-driven UI: Intuitive knob interface and open source firmware (based on Marlin), attractive modifications.
- Amazing accuracy: Layer resolution is as low as 0.0875mm and maintains consistent print quality for printers under $200.
At a glance specifications:
- Filament compatibility: PLA, ABS, PETG, TPU
- Nozzle temperature: Up to 275°C
- Connectivity: SD card, USB
- weight: 6.5 lbs (super easy volume)
Setup successfully: Calibration and first printing
Unboxing and assembly:
Minimalism to the core – Install filament holders and construction boards only. Power it and use the dial to browse the menu.
Key calibration steps:
-
Flat bed:
- Preheat the bed to 60°C for thermal expansion.
- Use paper to adjust each corner knob until a slight friction occurs.
For prompts: Repeat every 10-20 prints – the aluminum bed will bend!
-
A layer of adhesion:
- Start with the PLA of 190°C nozzle/60°C bed.
- Apply hairspray or glue sticks to the stock plate to prevent warping.
- Slicer setup (Cura is recommended):
- use "Single unit selection mini V2" contour.
- Start with a printing speed of 50mm/s and an initial layer of 20mm/s.
Print the prompt first:
Bundled test prints (for example, cats) verifies your settings. Don’t skip it!
Materials and practical applications
PLA: Best location for V2 – low smoke, clear details. Very suitable for the proof of concept CAD model.
Petg: Great for flexible/functional parts; raise the temperature to 230°C and then slow down the first layer.
ABS&TPU: Success factors vary due to open design (draft causes distortion). The shell is mandatory!
When to upgrade to a professional Suuport:
For complex geometric shapes, metal or end-use parts that require ±0.005 inch tolerance, desktop printer hit rate.
Maintain peak performance: Professional tips
- clean:
- During preheating, use a wire brush on the nozzle to remove the carbonized plastic.
- Clean the rods and bearings with 90% isopropanol every month.
- Unlock the nozzle:
- Heat to 230°C, push the silk manually or use an acupuncture needle as part of the jam.
- Parts cooling: Print and install the popular “Diicooler” fan mod – Kill PETG prints!
- Safety: Never leave prints unsupervised; V2 lacks thermal runaway protection (firmware that flashes like Kipper is added).
Solve FAQs
- Layer movement: Tighten the belt and verify the stepper motor voltage.
- string: Lower retraction distance to 4-5mm and increase the recovery speed to 40mm/s.
- Bed adhesion fault: Check the level, clean with alcohol or replace the stock surface with PEI.
- Overheated motor driver: If running > 3 hours of print volume, add the heatsink to the motherboard chip.

FAQ (FAQ)
Q1: Single-metal mini V2 printing carbon fiber wire?
one: Avoid using abrasive materials without upgrading. CF composites quickly wear brass nozzles. Stick to PLA+/PETG for durability. For industrial-strength carbon fiber or metal parts, explore Greatlight’s SLM printer that processes alloys like Alsi10mg with corrosion resistant decoration.
Q2: How long does it take for the heating bed to reach 60°C?
one: 60°C for 2-3 minutes. Maintain a printing temperature above 100°C? Unreliable. For high temperature materials like PEEK or ULTEM, our industrial SLS service offers a controlled environment and a 400°C chamber.
Q3: Why does layer transfer happen after weeks of perfect print?
one: Loosen belt/screw from vibration. Monthly tension checks and thread lockers on motor screws prevent sliding. Still facing problems? Your model may exceed the kinematic limit of V2. Greatlight handles multi-axis printing without layer defects.
Question 4: Can I upgrade the build volume of Mini V2?
one: MOD exists, but compromises stability. For parts > 120mm, consider outsourcing single unit printing. The Greatlight process uses 300mm x 300mm volumes of EOS M300-4 machines to effectively batch.
Q5: What post-processing does Greatlight provide? Desktop printers cannot?
one: In addition to printing, we also offer UV coatings, pressure-sensitive annealing, EDM texture and CNC-Tool finish. Do titanium parts that need waterproof and meet biological content? We ensure FDA/Military Specifications Compliance – the desktop ecosystem cannot be replicated.
