FDM 3D Printing

Properties

• Thermoplastic filament extruded layer by layer
• Wide material range (PLA, PETG, ABS, TPU, Nylon)
• Good strength-to-cost for functional parts
• Visible layer lines; post-processing optional
• Infill and wall settings tune stiffness and weight

Best applications

• Functional prototypes and fit checks
• Jigs, fixtures, and brackets
• Enclosures and mounts for electronics
• Low-volume production of plastic parts
• Education and university research models

Cost

Typically the most cost-effective process for mid-size plastic parts. Price scales with material weight, quality, and quantity — with steep volume discounts on larger orders.

Lead time

Usually 7–10 business days including free USA shipping. Rush options available on request.

Design guidelines

• Minimum wall thickness ~1.2 mm (prefer 1.5–2 mm)
• Avoid unsupported overhangs steeper than ~45°
• Add fillets at stress concentrations
• Design clearances of 0.3–0.5 mm for mating parts
• Orient critical surfaces to reduce stair-stepping
