Heat tolerance and machinability, indoors
ABS 3D printing
ABS (acrylonitrile butadiene styrene) is the plastic of LEGO bricks and car interiors: tough, heat-tolerant and pleasant to work with after printing — it sands, files, drills and solvent-smooths better than anything else we run. It was the standard functional material before PETG arrived, and it still earns its place when a part runs warm, but it demands an enclosed, heated machine to print without warping, which is reflected in the price.

Where ABS wins
- Working temperature around 95°C — dashboards, light housings, near-motor brackets
- Impact-tough without being bendy
- The best post-processing of any common material: sanding, drilling, tapping, gluing
- Acetone vapour smoothing can give a near-injection-moulded surface
Where it lets you down
- Warps and cracks if printed without a heated chamber — large flat parts are the hardest case
- UV exposure chalks and embrittles it within a couple of seasons — outdoors is ASA's job
- Layer adhesion is weaker than PETG's, so orientation matters more
- Noticeable odour in printing; needs managed ventilation
What gets printed in ABS
- Automotive interior pieces: clips, trim, brackets, cubby dividers
- Housings for anything that runs warm
- Parts that will be drilled, tapped, glued or painted after printing
- Functional prototypes standing in for injection-moulded ABS production parts
When to choose something else
If the part sees sunlight, choose ASA — it is ABS's outdoor twin and costs about the same. If it doesn't see heat either, PETG does the everyday job with fewer printing risks. And if the temperature is well past 100°C, no common printed plastic is honest for the job — that is a conversation about nylon, or about not printing it.
How it prints — and why that shows in the price
ABS needs an enclosed, heated chamber and careful orientation, and large flat parts carry genuine warping risk we will flag at quote time. Priced accordingly — a little more than PETG, and worth it only when its heat tolerance or machinability is actually used.
