Question 1

What materials are used for 3D printed products?

Accepted Answer

For general household items, we use eco-friendly PLA material made from corn starch. It is lightweight, sturdy, and safe for the human body. For products that are used with tools and require higher durability, we use PETG, a tough and flexible material. For more details, please refer to the product page.

Question 2

How do the materials affect the environment?

Accepted Answer

We aim to use renewable and biodegradable materials like PLA whenever possible. For products that require durability, we use BPA-free PETG. We also collect and recycle any waste materials generated during production.

Question 3

Are they easy to break?

Accepted Answer

Each product is designed and manufactured with the appropriate thickness and structure to ensure safety and durability.

Question 4

I see fine lines on the product. Is it defective?

Accepted Answer

Layer lines are a natural characteristic of 3D printing and are not a defect.

Question 5

Do the products warp or discolor?

Accepted Answer

PLA materials can be sensitive to high temperatures. Avoid exposure to temperatures over 200°C. Under normal indoor use, the products will maintain their condition for a long time.

Question 6

Why do surface textures differ between products?

Accepted Answer

3D printing is done layer by layer, and texture can vary depending on the printer model, temperature, speed, etc. Some textures are intentional design choices, and others may be post-processed for a smooth finish.

Question 7

The size seems slightly off. Is this normal?

Accepted Answer

A tolerance of ±0.2mm is standard in 3D printing. For precision parts or interlocking designs, we account for this variation. If there is any issue with actual use, please contact our customer service.

Question 8

Do the parts come assembled or separate?

Accepted Answer

Most items come pre-assembled. However, for protection during shipping, some products may be sent disassembled and include a simple assembly guide either on the product page or inside the package. If you encounter any difficulties during assembly, please contact customer support — we're happy to assist you promptly.

Question 10

I bought a mount. Are screws included?

Accepted Answer

Question 11

How long do the products last?

Accepted Answer

Unless exposed to high temperatures (over 200°C) for extended periods, the materials used retain their quality over long periods of use.

Question 12

Will the product break if strong force is applied?

Accepted Answer

Because 3D prints are made layer-by-layer, they can be weaker to twisting or strong impacts than injection-molded items.However, we consider these structural characteristics in our designs and conduct multiple strength tests to enhance durability.
