HIPS is a filament that South African makers reach for when they need soluble supports for abs, lightweight housings, hobby parts and budget functional parts. This guide covers what HIPS is genuinely good at, how easy it is to print on a typical desktop machine, whether it is food safe or UV stable, and the mistakes that trip people up, so you can decide if it is right for your project before you buy a spool or send it to a studio.
Printing HIPS: how hard is it?
On the bench, HIPS is easy to print. That makes it a great fit for a first printer such as a Bambu Lab, Creality or Anycubic machine, and it forgives the odd setting mistake. It releases a noticeable smell and fine particles while printing, so run HIPS in a well-ventilated space or an enclosure with filtration, not an unventilated bedroom.
An enclosure helps with consistency, and in load-shedding-prone workshops an uninterruptible supply avoids failed prints mid-job.
HIPS strengths
It is stiff and rigid, holding its shape under load, with reasonable everyday strength that copes with normal handling but is not meant for heavy structural loads.
HIPS tolerates warm conditions but can start to soften in a closed car or in direct summer sun, so it is better kept out of the hottest spots. HIPS is not UV stable and will go brittle and chalky outdoors under our strong sun, so keep printed parts indoors or paint and seal them.
Is HIPS food safe?
HIPS is generally not recommended for direct food contact: the additives and the porous printed surface make it a poor choice for anything you eat or drink from. Choose PETG or PP for food-adjacent parts instead.
HIPS outdoors in South Africa
Our climate is hard on plastics: intense highland UV, big day-night temperature swings and humid coastal air. HIPS is not UV stable and will go brittle and chalky outdoors under our strong sun, so keep printed parts indoors or paint and seal them. It copes with occasional damp but is not fully waterproof, so seal parts that will sit in water. HIPS tolerates warm conditions but can start to soften in a closed car or in direct summer sun, so it is better kept out of the hottest spots.
For permanent outdoor parts you may get longer life from a more UV-stable material like ASA, but HIPS is fine for shaded or short-term outdoor use.
HIPS cost and availability
HIPS sits at the budget-friendly end of the market. It is stocked by most South African filament suppliers, and you can compare current prices and colours on the 3D PrintZA marketplace, or send your file to a local studio that already runs it if you would rather not buy a whole spool.
The verdict on HIPS
HIPS is a budget-friendly, easy-to-print material that really shines for soluble supports for abs. Avoid it for food contact, outdoor without coating and structural loads. If that matches your project, find a South African studio that prints HIPS or buy a spool and run it yourself.
