• TPU (Thermoplastic Polyurethane) is a subclass of thermoplastics which prints strong parts that are also flexible.
• Compatible with all FDM printers on the market which accept 1.75 mm filament. Including Prusa i3, Monoprice MakerSelect, SainSmart x Creality, and other RepRap printers.
• With proper settings, TPU is easy to print thanks to excellent bed adhesion and the filament’s tendency to not warp.
• Great for a variety of projects, such as shoe insoles, watch bands, phone cases, drone parts and more!

PLA, or Polylactic Acid, is a commonly used thermoplastic material that does not require the use of a heated print bed. Because of the lower melting temperatures and lack of warping, PLA filaments retain their color vibrancy and are a common choice for displays or small household prints.

• No heated bed required.
• Less warping, more flexible than ABS filament.
• Easy to print. Printing temperature is 180°C - 200°C.
• Environment-friendly biodegradable material. No harm to human and environment.

Thermoplastic polyurethane (TPU) is a high strength flexible material. TPU belongs to the TPE class of thermoplastics

• Specially formulated plastic with increased amount of flexibility, with rigid structure.
• Resistant to oil, grease and abrasions
• Weight: 250g per spool (approximately 0.55 lb)
• Diameter: 1.75mm (+/- 0.05mm)
• Shore Hardness: 95A

This cost-effective 50g TPU is great for experimenting, printing items such as flexible phone cases, drone parts, and adding a little splash of color to your prints

• 1.75mm 50g per spool
• Specially formulated plastic with an increased amount of flexibility, with the rigid structure.
• Resistant to oil, grease, and abrasions.
• Recommended extruder temperature: 210 - 230°C Recommended platform temperature: 30 - 40°C
• Flexible Filament does not feed well on all 3D printers. Direct feed extruder is recommended.
• Vacuum-sealed packaging

Are you tired of tangles spools ruining hours of printing? Are you looking for an all-around filament to get you started with your first 3D prints? We are excited to tell you that SainSmart PRO-3 series PLA filament can resolve all your concerns.

No Jamming at All

Supported by an all-new technology called layer by layer, PRO-3 is featured with 100% tangle-free. This ensures the filament printed extremely smooth and no more extruder become clogged again.

Laser Precision

Inspected by laser, PRO-3 ensures each inch of filament is precisely engineered to +/-0.02mm error rate. Consistent round shape avoids unexpected interruption in printing.

Smart Indicator

A smart length indicator is present on the surface of the clear PC spool for your convenience to know the length of your remaining filament.

Eco-Friendly

Made from the natural renewable resource, the filament is 100% biodegradable & non-toxic.

Practical for All Users

PLA is considered as one of the most commonly used filament for both beginners and experienced users.
