Weefun TINA 2 PLUS 3D Printer Review - Mods!

Summary

In this detailed review of the Weefun Tina 2 Plus 3D printer, the user shares their experience with modifications, print quality, and performance. Key highlights include impressive TPU and PLA print results, with suggestions for improved filament handling using Capricorn tubes. The reviewer also addresses noise reduction and the need for better hot-end durability, noting concerns with the proprietary nozzle. Overall, the printer delivers great value for its price, though some may find the hot-end design limiting. Despite a few tweaks and concerns, the Weefun Tina 2 Plus earns a thumbs-up for its overall performance and quality.

Takeaways

• 😀 The WeFend Tina 2 Plus 3D printer requires minimal modifications to improve its performance, such as tightening screws to reduce bed play and using Capricorn tubing for better TPU printing.
• 😀 With the right modifications, TPU retraction issues can be resolved, enabling smooth printing with flexible filament at retraction speeds of 6-7mm.
• 😀 The printer performs excellently across multiple filaments, including TPU, PLA, and PETG, with great print quality and minimal complaints about the results.
• 😀 The printer is capable of printing at high speeds (150mm/s) while maintaining solid print quality, making it versatile for different projects.
• 😀 Modifications like adding feet to the printer help reduce noise and improve airflow to key components, enhancing both print quality and durability.
• 😀 The standard hot end is a combined unit, meaning users cannot easily replace just the nozzle. This could be a drawback for those who prefer individual nozzle replacements.
• 😀 The hot end uses brass, which the reviewer feels should be upgraded to hardened steel for better durability, especially given its proprietary nature.
• 😀 The noise from the printer's fan is noticeable, but this can be alleviated by installing a step-down converter, though a firmware update could address this in the future.
• 😀 The printer’s belt tension was spot-on out of the box, making setup easy and reducing the need for major adjustments.
• 😀 Despite the concerns with the hot end and nozzle, the printer delivers high-quality prints for both slow and fast speeds, making it a good budget option for users who need reliability and performance.
• 😀 The proprietary hot end design could be a challenge for some users due to the cost and availability of replacement parts, particularly for the nozzle, which is sold as a complete unit.

Q & A

What was the main issue with the extruder setup that needed modification?

The main issue was the play in the extruder, which caused retraction problems, especially with TPU. Tightening the screws to reduce play helped resolve this issue.

How did the Capricorn tube improve the printer's performance?

The Capricorn tube, being high tolerance, allowed the user to perform retractions at higher settings (up to 7mm) without causing binding or extrusion issues, which was not possible with the stock tube.

What specific modification was made to reduce noise from the printer?

The reviewer wired in a step-down power supply to lower the fan speed, reducing the overall noise produced by the printer during operation.

How does the printer perform when printing TPU at various speeds?

The printer performs exceptionally well with TPU, even at higher speeds (150mm/s), producing high-quality prints with clean and uniform layers.

What was the significance of printing at slower speeds with TPU?

Printing TPU at slower speeds (50mm/s) allowed the printer to produce very high-quality prints with excellent layer consistency and sharp detail.

What was the issue with the printer's hot end that the reviewer highlighted?

The reviewer was concerned about the proprietary hot end design, as it requires replacing the entire assembly rather than just the nozzle. Additionally, the nozzle is made of brass instead of hardened steel, which could affect longevity.

How did the reviewer feel about the availability of replacement parts for the hot end?

The reviewer expressed concern that after the one spare nozzle provided, users would need to buy a whole new hot end if they needed replacements, potentially making it more expensive and less convenient.

Was the printer's performance at higher speeds adequate for PLA printing?

Yes, the printer handled PLA printing well, even at 150mm/s. The reviewer noted that the prints were of good quality, with very little to complain about regarding the speed.

Why did the reviewer print feet for the printer, and what benefits did they provide?

The reviewer printed feet for the printer to raise it off the ground. This modification not only reduced noise but also allowed better airflow to the stepper drivers and other components beneath the printer.

How did the reviewer feel about the overall quality and value of the WeFunda Tina 2 Plus printer?

The reviewer was impressed with the overall performance of the WeFunda Tina 2 Plus, especially considering its affordable price. Despite some minor drawbacks like the proprietary hot end, the printer offered high-quality prints and fast performance.
