PLA is a strong, stiff biodegradable plastic. Its processed using a FDM printer, meaning its enters the printer in filament form, its heated to melting point and extruded out the print head as it prints into its final shape. It has properties that we have found are suited well for a range of difficult geometries including forms prone to warping. 

It has a remarkably low shrinkrate of 0.1-0.2% which is how we produce forms within tolerance and free of warping.

The filament diameter is highly accurate (+-0.03mm) so parts are free of inconsistancies. All our PLA is kept dryboxes always, this ensures the plastic absorbs no moisture which would decrease print quality in ways you can and cant see with our eyes.


Its elongation at break is 20% which prevents it from becoming brittle,provides a little flexibility and improves impact resistance.

Our default print settings apply a wall thickness of 1.2mm and a hexagonal infill pattern of 20% density. Our maximum infill density is 50%, anything more than that clogs the machinery and adds almost no extra strength.


Typically its best suited for prototyping purposes, its cheap so its more affordable when many iterations are required. Its lower detail than SLA resin and the build lines are visible to the eye, but its accurate and more than detailed enough for a huge variety of applications.

Cost Effective

PLA plastic the most used filament in FDM printing as its cheap and has a great balance of mechanical properties that suit many uses. PLA is a great choice when you need large batches given its low unit cost. 

Strong & Stiff

Its strong and impact resistant like ABS. Its lots more rigid then ABS and more environmentally friendly. Parts thicker than 10mm can withstand large forces without any permanent bending.


PLA has a extremely low shrink rate (0.1-0.2%) which makes its great for functional parts that require high dimensional accuracy. Generally speaking if the part is less that 100mm long then it will be within 0.1mm of its target size.

Environmentally friendly

PLA plastic is derived from corn starch which catergorizes it as a biomaterial. Its not just recyclable, its compostable too. It can last some time in standard compost but commercial composts with elevated temperatures fully break it down in as little as 30 days.


The vast majority of our prints are within +-0.2mm (or +-0.2%). We offer a garuanteed tolerance of +-0.4mm (or 0.4%), however 95% of our parts are significantly more precise than the minimum tolerance we offer.

Generally speaking if the part is less that 100mm long then it will be within 0.1mm of its target size. 

In rare cases some geometries are prone to warping which can lead to results outside of the garuanteed tolerance, if this is the case we can usually reorientate the print direction to compensate.

Below you will see pictures of the PLA prints fresh out of the printer. Unlike resin PLA comes as it comes and not much can be done in the way of surface finishes. By default we remove all printing supports. The surface is a little glossy. Build lines are visible upclose when printing with a 0.2mm layer height setting.
