3D Printing and Engraving

Thermoplastic polyurethane (TPU) belongs to a class of polyurethane plastics having many important properties such as elasticity, transparency, and resistance to grease, oil, and abrasion. It is unique due to its extremely flexible nature. Technically speaking, TPUs are made up of thermoplastic elastomers.

TPU has different advantages such as resistance to abrasion, ability to perform at low temperature, elasticity, and mechanical properties along with rubber-like elasticity.

TPU printing filament is flexible in nature. It can bend easily without any effect on the design, strength and durability. A mild soap can be used for its cleaning.

Flexible TPU filaments can be stored in a cool airtight container. Container may also have a desiccant pack, so that filament remains bone dry. This container can also help in preventing the entry of dirt and dust particles, so that the filament could be used anytime for print. Although some type of TPUs are water-resistant, prolonged contact with water could result in degradation of the product.

For optimal results print flexible TPU filaments on direct extruders; however, it is possible to print on Bowden extruders as well. Flexible TPU filaments have the ability to adhere well to most surfaces such as glass, aluminum, Kapton tape, and blue painters tape. It is important to always print in a well ventilated room regardless of the filament type.

The DaVinci Lab PETG 3D printer filament (Polyethylene Terephthalate) is one of the most common used polymers today. It is also used in the manufacture of food packaging, water bottles and many other common plastic items. PETG filament has proven its worth as a durable material that is easy to use. Figuratively speaking, it combines the most useful characteristics of ABS filament with the ease of printing that PLA filament affords.

PETG features:

• Higher strength
• Lower shrinkage
• Combines good strength with ductility, making it a good, tough material for mechanical parts
• Good chemical resistance
• Contains UV absorber
• Good hydrophobicity (does not absorb water easily)

The DaVinci Lab PETG filament has the following characteristics:

• 100% virgin material without cheap plastic fillers
• Print Temperature: 210 – 250°C, dependent on printer model
• Heat Bed temperature: 90 – 110°C
• 1Kg net weight
• Accurate diameter of 1.75mm with a tolerance of ± 0.05mm
• Spool Size: diameter 197mm, inner hub 60mm & height 60mm
• Vacuumed Sealed With Desiccant
• ROHS Certification from SGS testing

   additional cooling).
   A simple steps and direction control interface
   Six different steps resolutions: full step, half step, 1/4-step1/8-step1/16-step, 1/32-step
   CAN interface directly with 3.3 V and 5 V systems
   Over-temperature thermal shutdown, overcurrent shutdown, undervoltage lockout
   Short to ground short circuit load protection
   4 Layer 2 oz copper PCB, in order to improve heat dissipation
   Exposed solder ground below the bottom of the driver IC on the printed circuit board pad
   Module size, pin and interface matching A4988 stepper motor driver operators in many ways
   Adjustable current control lets you set a potentiometer, which lets you use the stepper motor's
   rated voltage or more, in order to achieve a higher rate of maximum output current step
   Intelligent chopping control automatically selects the correct current decay mode (fast decay or
   slow decay)
   Maximum 45 V supply voltage
   Built-in voltage regulator (the need for any external logic supply voltage)
