There are several drawbacks to using plastic for model building. While plastic is a common material used in model making due to its affordability and versatility, it also comes with its own set of limitations and challenges. Let’s explore some of the drawbacks of using plastic for model building:
1. Limited detail
Plastic models often have limitations when it comes to capturing fine details. The manufacturing process of plastic injection molding can sometimes result in loss of intricate details, leading to a less realistic final product.
2. Fragility
Plastic models can be more fragile compared to models made from other materials such as wood or metal. Thin plastic parts can easily break or warp, especially during assembly or when handling the finished model.
3. Limited customization
While plastic models are available in a wide range of kits and designs, they can be limited in terms of customization. It can be challenging to modify or customize a plastic model beyond what is provided in the kit, restricting the creative freedom of model builders.
4. Environmental impact
Plastic is a non-biodegradable material that can have a significant environmental impact. The production and disposal of plastic models contribute to plastic waste pollution, which can harm the environment and wildlife.
5. Painting challenges
Painting plastic models can be tricky due to the smooth surface of the material. Paint may not adhere well to plastic, leading to issues such as chipping, peeling, or uneven coverage. Proper surface preparation and priming are essential for achieving a professional-looking paint finish on plastic models.
6. Limited durability
Plastic models may not be as durable as models made from other materials. Over time, plastic can degrade or become brittle, especially when exposed to sunlight or fluctuating temperatures. This can affect the structural integrity of the model and lead to deterioration over time.
7. Difficulty in repairs
Repairing a damaged plastic model can be challenging, especially if the breakage occurs along a seam or joint. Gluing plastic parts back together may not always result in a seamless repair, and the repaired area may be visible or structurally weaker than before.
8. Limited realism
Despite advances in plastic molding technology, plastic models may still lack the realism and authenticity of models made from other materials such as resin or metal. The glossy finish of plastic can sometimes give a toy-like appearance to the model, detracting from its overall realism.
9. Cost of quality
While plastic models are generally more affordable than models made from premium materials, achieving a high-quality finish on a plastic model can require additional investment in tools, paints, and finishes. The cost of quality materials and tools can add up, making plastic model building more expensive in the long run.
10. Limited scale options
Plastic models may be limited in terms of available scales, especially for niche or specialized subjects. While popular subjects may have a wide range of scales to choose from, more obscure or specific models may only be available in a limited number of scales, limiting the options for model builders.
