taulman3D, an innovative 3D printer materials development company has released their new high-strength In-PLA PLA material, according to a statement released today by the company. "With our new In-PLA PLA material, we not only bring a new color clarity and capability, but the additional strength taulman3D materials are noted for."

In-PLA is a non-yellowing PLA and will allow more colors and better color matching. The added claity also allows the user to take advantage of the 3D Printing epoxy "XTC-3D" to enhance clarity.

Strength:

  • Ultimate Tensile Strength: 9.89 ksi, ASTM D638
  • Tensile Modulus: 521.6 ksi, ASTM D638
  • Tensile Strain at Break: 3.9%, ASTM D638
  • Gardner Impact Strength: 2.04 in-lb, ASTM D5420
  • Flexural Modulus: 285.99 ksi, ASTM D790

PLA has traditionally been regarded as a material that allows easy and trouble free printing. Its properties allow it to adhere to a variety of surfaces at a relatively low temperature.

"While the small shrinkage feature is a significant advantage of PLA, we wanted to bring PLA closer to the utility side of 3D Printing," said Thomas Martzall, the man behind Taulman3D. "With In-PLA, we have developed this additional strength and look forward to new uses and applications where a stronger PLA can fill a need. As a material to be used by design houses for "Form/Fit", it was also important to bring a material that can more closely align with color and gloss expectations. The clarity of In-PLA needed to meet a transmission specification of 90% at 2mm when formed to an optical flat, or thick film "without a yellow tinge". This was a difficult specification to reach, but will allow follow–on colors or special orders to be more easily matched to standard industrial color swatches. We also wanted In-PLA to take advantage of the optical correction capability of being coated with "XTC-3D", a clear, 2 part coating that corrects for zero DOF of clear plastic threads."

Unlike other taulman3D materials, it is releasing In-PLA on 1kg spools. In-PLA prints at 207C – 212C, and all other settings are identical to standard PLA configurations for print speed and printing surfaces. It is available in 1.75mm round and 2.85mm round and priced at $49.95 / spool. Initial release colors include: Clear/Natural, Opaque White, Opaque Black, Translucent Red, Translucent Blue, Translucent Green.

"The next major effort for us was to add an extrusion mfg line. A little known fact about taulman3D is that our materials are not extruded, but are "drawn"," said Martzall. "A manufacturing method where the material comes out of the main heaters larger in dia, and then drawn or "stretched" under water to size specifications. This unique manufacturing method allows us additional control of the final taulman3D material features when 3D Printed."
