Summary

It is discontinued at Monoprice and B&H lists it as no longer available, so check what a used or old-stock unit costs you against a new entry-level printer before you buy.

Strengths

  • Six-bolt assembly and sample models on the SD card get you printing within minutes.
  • Highly upgradeable open frame — fan duct, Z-brace, glass bed, all-metal hotend — backed by a large Duplicator i3 modding community.
  • No filament lock-in: any brand of filament and any slicer works.
  • A long-term owner printed hundreds of models over 10+ months and still called the print quality very high, with no mods.

Weaknesses

  • ABS struggles on stock hardware: layer separation and repeated bed-adhesion failures in independent testing, on a bed capped at 70–75 °C.
  • Bed leveling is manual and fragile — the thumbscrews are easy to bump out of calibration.
  • First-print failures (no extrusion, SD files not detected) recur in new-owner threads from 2016 to 2025.
  • Support is repeatedly described as slow or unhelpful, especially once the one-year warranty expires.
  • No filament sensor, no Wi-Fi, no automatic bed leveling.

What independent testing found

TechGearLab ran 45+ side-by-side tests in June 2017 and scored the printer 5.3/10 at a $260 list price: print quality 5/10 with a subpar benchy in both PLA and ABS, ABS layer separation and noticeable Z-axis wobble; capabilities 6/10 after multiple ABS prints detached from the bed partway through, even with adhesive and a raft; support 6/10 after Monoprice told them to return the unit for what seemed a simple print-quality issue. 3D Insider’s June 2018 review landed kinder — an excellent budget printer with long-term value for a tinkerer — while confirming the bare feature list and noting that once the one-year warranty lapses, in their words, Monoprice “no longer cares about your problems”.

Bed, ABS and running costs

For ABS-class printing, plan on upgrades — glass bed, all-metal hotend, enclosure. The MK10 extruder is a known, replaceable ecosystem part, and the open frame means printed upgrades are everywhere in the Duplicator i3 community.

First prints and support

New-owner threads keep hitting the same wall: a December 2016 r/3Dprinting thread about a 13860 that would not print, a 2025 thread titled “not extruding at all”, and a 2022 r/3dprinter thread from an owner who never really got the V2 working well.

Support follows the same pattern: TechGearLab was told to return the unit over a simple print-quality issue, and 3D Insider reports slow inquiry handling, especially refunds. Any unit you can buy today is years past that one-year warranty.

Is it worth it?

The value case is time-stamped. Monoprice launched the V2 in August 2016 at $349.99; by June 2017 TechGearLab measured a $260 list price, and an owner who bought one in June 2016 paid about $300. An undated Treatstock snapshot averaged $299. At those 2016–2017 street prices it was a defensible entry point for a hobbyist willing to tinker; at the $349.99 launch price, less so.

Today the math changes. Nobody has published failure rates for this model. Otherwise, weigh it against a current entry-level enclosed printer.

Which model this is

It is externally identical to the Duplicator i3 except for the spool holder, which sits on top of the frame rather than on the control box. Its Amazon listing is ASIN B06Y3YB4HP. Don’t confuse it with the smaller MP Select Mini V2, the later Maker Select Plus, or Duplicator i3 printers sold under other names. Accessory lists also varied between production runs: the quick-install guide lists a 2 GB microSD card, B&H’s bundle a 4 GB one.
