This model features 3D printed parts: There are two types of 3D printed parts we use in our products. "FDM" is lower cost, and is what most would recognize as traditional 3D printing. This type of model printed in layers from thermal plastic (generally PLA or PETG), and is lightweight with reasonable detail but will have visible striation (or lines) that the hobbyist may want to clean up using putty, primer, or other hobby techniques. "SLA" is a laser cured photo-resin that has exceptional detail, and generally has a much smoother finish without significantly noticeable striation. This type of material is more expensive, and fine details can be more delicate. Some models may use either or both types of parts, and some models may have the ability for the buyer to select the print type under print options. These models are intended to be painted and may come in different colors.
