3D printing

Smooth-On XTC-3D™ coatings for finishing 3D printed parts.

• Smooths printed layer lines
• Cures to a hard coating
• Can be sanded and painted
• Compatible with SLA and FDM
• For models, props and prototypes

PLA (Polylactic Acid) is the most widely used plastic filament for FDM 3D printers.

It is a bioplastic made from renewable resources like cornstarch or sugarcane and emits a sweet scent during printing.

• Prototypes and concept models.

• Detailed figures, display models, and cosplay items.

• Educational projects in schools.

• Household decor that is not heavily stressed.

Key Properties

• High heat resistance: Maintains its shape up to 80–90 °C

• Impact-resistant and tough: due to its slight mechanical flexibility.

• Weather- and UV-resistant: Good for outdoor use; it does not degrade under sunlight.

• Chemical resistance: Highly resistant to water, acids, and chemicals.

• Odorless printing: Emits virtually no odor while melting and does not require an enclosure like ABS.

Properties

• UV and Weather Resistance

• High Durability: impact resistance, tensile strength, and rigidity.

• Heat Tolerance: Handles higher working temperatures than standard plastics

Uses

• Outdoor Applications: Signs, exterior housing, and garden fixtures.

• Automotive Parts: Mirrors, exterior trim, grilles, and under-hood components.

• Functional Prototypes: Durable mechanical parts and waterproof housings.

Key Properties

• High Impact Toughness: It absorbs mechanical stress without snapping.

• Temperature Resistance: It retains its shape and structural integrity up to 85°C–90°C.

• Acetone Post-Processing: It can be chemically smoothed with acetone vapor to eliminate 3D-print layer lines.

• Easy Machining: It is highly versatile after printing, allowing you to easily sand, drill, or paint the finished product.
