the disadvantages of 3D printed saddles mainly include the following aspects

1. High cost: Although 3D printing can save materials, its initial investment and operating costs are still relatively high. The price of seat cushions is usually much higher than traditional seat cushions, partly due to the higher purchase and maintenance costs of 3D printing equipment.

2. Material limitations: Currently, the types of materials available for 3D printing are limited, and the cost of certain advanced materials such as certain metals or special plastics is high, which limits consumers' choices. In addition, some materials may not be as comfortable as traditional materials, and users need to adjust the seat cushion position themselves to avoid discomfort.

3. Comfort issue: Although 3D printing technology can be designed and adjusted based on ergonomic data, the comfort of some 3D printed seat cushions may not be as good as traditional ones. For example, although Pantani's 3D printed seat cushion is lightweight and breathable, its comfort level is not as good as Lightning Snitch's fully wrapped seat cushion.

4. Poor anti slip performance: Due to material reasons, the anti slip performance of 3D printed seat cushions is not as good as leather seat cushions, making them prone to sliding during cycling.

5. Professional equipment and technology are required: 3D printing requires specialized equipment and operational skills, which increases production and time costs. In addition, the maintenance and operation of 3D printing equipment also require a certain level of professional knowledge.
