How is the ranking computed?
Each metric is normalised and combined with goal-specific weights (support, height, surface roughness, bed contact).
From the tool guide Ask a follow-upDoes it consider strength?
Only indirectly via stability; layer-direction strength depends on loads, which the tool cannot know.
From the tool guide Ask a follow-upCan it handle big models?
Yes, though models above ~500k triangles take a few seconds per analysis.
From the tool guide Ask a follow-upIs my model uploaded?
No — everything is calculated in your browser.
From the tool guide Ask a follow-upWhat this tool does
Orientation decides how much support a print needs, how long it takes, how rough its surfaces are and how strong it is. This tool tests every large flat face of your model (laid on the bed), the six axis directions and a 40-point sphere sample. For each candidate it measures build height (a time proxy), bed-contact area (stability and adhesion), overhang area and support volume (overhangs cast to the bed) and visible stair-step area (near-horizontal curved surfaces whose layer lines show).
How to use it, step by step
- Drop in your model.
- Choose your goal and overhang angle.
- Press Analyse orientations.
- Preview the top results and download the best STL.
Tips from the guide
- For strength, consider the load: keep layer lines parallel to the direction of tension.
- Surface quality matters most on visible faces; tilt them away from near-horizontal.
- Tall, thin orientations are slower and wobble — check the bed-contact column.
- Combine with the overhang checker to inspect the chosen orientation.
Common mistakes to avoid
- Choosing the lowest-support orientation without checking bed contact (unstable towers).
- Ignoring layer-line direction on functional parts.
- Trusting a single score — look at the table.
Who uses it
- Makers with complex models. Skip trial and error orientation.
- Print farms. Standardise orientation to cut support and time.
- Engineers. Choose layer direction for strength.
How to ask a question people can answer
A good thread on the 3D Print Orientation Optimizer saves everyone time. Start with a title that names the exact problem, such as the input you used, the result you expected and the result you got. A title like “Not working” is hard to answer, while a title with the specifics gets replies quickly.
- Say what you tried. List the steps you followed and any settings you changed, so replies do not repeat what you already did.
- Share a small example. A short sample input and the output you saw is worth more than a long description. Remove anything private first.
- Mention your setup. Your device, browser and whether you are on a phone or a computer can explain many odd results.
- One question per thread. Separate topics get clearer answers and are easier to find later with the search box above.
- Come back and reply. If a suggestion worked, say so and upvote it, and if you found the fix yourself, post it for the next person.
