I. Introduction

In this review, we will thoroughly examine the Easythreed K7, an affordable desktop 3D printer that is perfect for beginners, students, and hobbyists on a tight budget. With its compact build volume of 120 x 120 x 120mm and wallet-friendly price point, the K7 aims to deliver reliable and user-friendly FDM 3D printing capabilities without breaking the bank. Our objectives in this review are to assess the specifications of the K7, evaluate its printing performance, and determine whether it offers great value for its cost.

II. Unboxing and Setup

The K7 arrives well-packed in a sturdy cardboard box. Upon opening, we found all components neatly organized with protective foam inserts. Included in the box are:

1.Fully assembled K7 printer body

2.1KG spool of PLA filament

3.USB cable

4.Quick start guide

Assembly is simplicity itself, as the K7 requires no assembly out of the box. We connected the included USB cable and loaded the included PLA filament. Software installation was smooth - we downloaded the latest version of the Easythreed Printing app from the manufacturer's website. Leveling the build plate took about 10 minutes using the manual bed leveling knobs. Overall, setup was a breeze and we were printing our first test model within an hour of unboxing.

III. Specifications

The K7 has a build volume of 120 x 120 x 120mm, suitable for small to medium sized prints. It uses a 0.4mm nozzle and claims a layer resolution of 0.1-0.4mm. Connectivity is via USB only, with the printer controlled through the Easythreed Printing app (Windows/Mac/Linux compatible). Key specs include:

Build Volume: 120 x 120 x 120 mm

Nozzle Diameter: 0.4mm

Layer Resolution: 0.1-0.4mm

Material: PLA

Connectivity: USB

Included: 1kg PLA filament, USB cable

IV. Printing Experience

For our first test print, we sliced and printed standard 20mm calibrated cubes as well as several mini figurines. Print quality is very good, price point - layer adhesion is good, minimal anomalies. The dimensional accuracy is within 0.2mm of the model size. The surface finish is very good, no visible workpiece.

We observed reliable layer bonding and found that the K7 had no problems with retractions or strings, even in standard Settings. Cooling is enough to prevent large fingerprint distortions. We were able to easily remove well-cooled prints from the build board without damaging them. Slicing and printing additional miniatures and actual objects is no problem.

V. User Experience

The K7 has an intuitive and straightforward user experience. Controls are accessed through the Easythreed Printing app using simple on-screen buttons and sliders. Heating times were respectable, reaching printing temperatures in under 5 minutes from a cold start. During operation, the K7 was pleasantly quiet at around 45dB, comparable to normal conversation.

Removal and replacement of prints and filament was hassle-free. Removing well-cooled prints required little pressure, while swapping filament simply required pushing the old filament out and threading in the new. Overall, everyday use proved easy and approachable for beginners.

With its user-friendly design, reliable performance and competitive price point, it's no surprise that the Easythreed K7 has been named one of the "Best 3D Printer of 2023" by leading publications. For beginners looking for their first affordable desktop 3D printer, or enthusiasts on a budget, the K7 proves a top choice that simply works.

VI. Value for Cost

At just $89, the Easythreed K7 offers remarkable value given its specifications and performance. While build volume is limited, printing quality matches many printers 2-3 times the price. Components like the heated bed, extruder, and sturdy metal frame feel high quality for the cost.

Compared to competing entry-level printers in this price range, the K7 stacks up well - delivering equal or better specs, user experience, and print quality. Backed by a 1-year warranty and continued software/firmware support from Easythreed, the Easythreed K7 proves itself as a reliable choice. For users on a tight budget, it's hard to imagine getting greater performance at a lower cost.

VII. Who Would Enjoy This Printer

The Easythreed K7 is perfect for beginners who are just starting out with 3D printing. Its plug-and-play setup and intuitive software make it ideal for students and classrooms. With a price tag of less than $100 and a low barrier to entry, it also appeals to people on a budget.

Enthusiasts looking for an affordable secondary printer prototype for small parts or mini will find the K7 ideal as a workspace companion. Its small size doesn't match that of an industrial machine, but it works well on occasional personal projects or one-off projects that don't require high precision.

VIII. Room for Improvement

With build volume its biggest limitation, a slightly larger printing area would open up more possibilities. An optional draft shield or auto-leveling would ease use for beginners. Basic smartphone control via app would also enhance accessibility.

However, given the K7's low price, these aren't deal-breakers. Tradeoffs are to be expected, and overall usability remains high considering cost - a great value for onboarding new users.

IX. Conclusion

In summarizing, the Easythreed K7 proves itself a top choice for those seeking a budget-friendly, easy-to-use desktop 3D printer. Specifications match or exceed competitors at this price point, while printing performance and reliability impress for the low cost. Setup is a breeze, and the intuitive software simplifies the learning curve.

At under $100, it's difficult to find a more affordable capable machine. The K7 makes 3D printing approachable for new users, students, and hobbyists. For its competitive value, reliability, and plug-and-play operation, we fully recommend the Easythreed K7 for those seeking an entry-level desktop 3D printer.
