Pretrained computer vision classifier

Identify 3d printed or not with one API call.

A pretrained 3d printed or not classifier that sorts an image into one of 2 categories. Use the 3d printed or not API immediately, no training required, then adapt it to your own data when you need more.

What this 3d printed or not classifier recognizes

A sample of the 2 labels this pretrained classifier chooses between.

3d printed
Not 3d printed

Call the 3d printed or not API

Once you've added this classifier to your console, you get your own copy of it behind your own endpoint. Invoke it with any HTTP client:

curl

curl -X POST "https://www.nyckel.com/v1/functions/YOUR_FUNCTION_ID/invoke" \
  -H "Authorization: Bearer $NYCKEL_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"data": "https://example.com/photo.jpg"}'

Python

import requests

# Get an access token: https://www.nyckel.com/docs/api/overview/authentication/
token = "YOUR_ACCESS_TOKEN"

response = requests.post(
    "https://www.nyckel.com/v1/functions/YOUR_FUNCTION_ID/invoke",
    headers={"Authorization": "Bearer " + token},
    json={"data": "https://example.com/photo.jpg"},
)
print(response.json())

Example response

{
  "labelName": "3d printed",
  "labelId": "label_...",
  "confidence": 0.92
}

Under the hood

Model type
Nyckel-trained

Trained on a Nyckel-curated dataset covering 2 3d printed or not categories, served on Nyckel's own infrastructure — your image stays on Nyckel.

Input
Image

Send an image URL or file to the invoke endpoint; the response is a label with a confidence score.

Make it yours
Adaptable

Clone it, then correct predictions and add your own samples in the console — Nyckel retrains automatically, turning this into a custom model tuned to your data.

More than a demo: this page is one of thousands of pretrained functions on Nyckel, an ML classification platform. You can invoke classifiers by API, review predictions, correct labels, collect samples from production traffic, and promote any pretrained function to a private custom model — without changing your integration.

Where teams use 3d printed or not classification

Manufacturing Quality Control

Detect manufacturing defects unique to 3D printed objects. Ensure products meet design specifications and quality standards.

Intellectual Property Protection

Identify potential copyright infringements of 3D printed designs. Verify the authenticity of licensed 3D printed products.

Customs and Border Security

Screen imported goods for 3D printed items that may bypass regulations. Identify potentially dangerous or prohibited 3D printed objects.

Art Authentication

Distinguish between traditional sculptures and 3D printed replicas. Verify the originality of artworks in galleries and museums.

Aerospace Industry

Inspect aircraft parts to ensure they're not unauthorized 3D printed components. Validate the use of approved 3D printed parts in maintenance and repairs.

Medical Device Regulation

Identify unapproved 3D printed medical devices or prosthetics. Ensure compliance with safety standards for 3D printed medical equipment.

Archeological Research

Differentiate between genuine artifacts and 3D printed replicas in collections. Validate the authenticity of newly discovered objects during excavations.

Common questions

What's the difference between a zero-shot and a Nyckel-trained classifier?

A zero-shot classifier uses a large foundation model's general knowledge to pick between your labels — no task-specific training, so new or edited labels work immediately. A Nyckel-trained classifier has been trained on labeled examples and runs on Nyckel's own infrastructure, which typically makes it faster, cheaper per call, and more accurate on data that resembles its training set. The "Under the hood" section on this page shows which kind this classifier is, and any classifier can be adapted into a trained one by adding your own examples.

How do I know whether this will work for my application?

Honestly: we can't know in advance — it depends on your data stream and how closely it resembles what this classifier has seen. The reliable way to find out is to measure it on your own data: start invoking the classifier with real traffic, or upload and annotate a set of images in the console — make sure they look like your production data, not idealized examples. Nyckel's evaluation metrics then show you exactly how it performs on that data before you rely on it.

What happens when it makes a mistake?

No classifier is perfect, so Nyckel is built around the correction loop: invokes can be captured for review, you confirm or correct predictions in the console, and corrections become training data. Over time the model adapts to your data distribution — accuracy on your traffic improves with use rather than staying fixed.

Do I need training data to get started?

No. This 3d printed or not classifier works out of the box — clone it into your console and you'll have your own API endpoint in under a minute. Training data only enters the picture when you want to adapt it: your corrected predictions and uploaded samples improve the model, and you can also edit the label set to match your needs.

What does it cost to try?

Trying the classifier on this page is free with no signup. Cloning it requires a free account, and the free tier covers your first API calls each month — see nyckel.com/pricing for current limits and paid tiers.

Ready to classify 3d printed or not at scale?

Add this pretrained classifier to your Nyckel console — you'll get a live API endpoint in under a minute, and a path to a custom model when you need one.
