Applications

Simple early-stage parts; cost effective way to produce many iterations

About the material

PLA is a great 3D printing material for early stage prototyping on simple geometry parts, made out of biodegradable corn starch. Because this material is relatively cheap, you can cost effectively 3D print multiple iterations of an early stage part design.

Note this is a hobbyist-grade material and the resulting precision will vary on each order. Our network’s machines are optimized for speed over precision for PLA parts. We recommend PLA for cheap, fast prints and not for accuracy or final models.

Material Properties

Tensile Strength

28.1 MPa (4075 PSI)

Elongation at Break

1.4%

Modulus of Elasticity

1879 MPa (272526 PSI)

Flexural Strength

48 MPa (6962 PSI)

Material Finish

PLA has the roughest finish of any material that we offer. This is primarily due to the fact that support material is manually broken off, sometimes leaving residual material or rough surfaces. Complex geometry and parts with lots of curvatures will show the stepping of each layer in greater detail.

We don’t recommend using PLA for prototypes that need very accurate geometries or aesthetic appeal due to the low material resolution and visible step lines.

Design Recommendations

Max Part Size [x, y, z]

304 x 304 x 600 mm
12 x 12 x 24 in

Min Clearance + Gaps for Fit

0.5 mm

Min Wall Thickness

1 mm min

Internal Cavities

All internal cavities will have support material inside.

Threads & Inserts

For PLA, we recommend you use heat stake inserts. For more information, check out our article on The Best Fasteners for 3D Printed Parts.

Text Guidelines

Engraved text (indented) is recommended over embossed, since PLA is not able to capture fine details very well.

Enhance Your 3D Printing Workflow With CNC Machining in Post

If you’ve ever designed and 3D printed a part that required high dimensional accuracy, you were probably disappointed with the outcome. Maybe a bolt didn’t fit into a 3D printed hole, or a 3D printed bracket didn’t fit into its intended recess. Whatever the dimensional intention, it’s likely that the 3D printed part didn’t serve […]

CNC Operations and Applications

CNC or Computer Numerical Control is, by itself, useless. Without hardware to execute the commands, CNC is nothing more than an array of vectors stored on a drive. Once CNC is married to a machine operation, however, the manufacturing possibilities are practically limitless! What is CNC? What exactly is Computer Numerical Control? Essentially, it’s when […]
