Making Money from Home by Designing Models for 3D Printer Owners

If you have a computer at home and want to learn how to design three-dimensional objects, you can turn it into a freelance service over time. Moreover, you do not necessarily need to have your own 3D printer in this job. Some customers only need the digital model file.

The job here is to create a three-dimensional digital model of an object. This model can be a simple desktop organizer, cable holder, decorative object or prototype piece. Depending on the customer's needs, files used in 3D printing such as STL or model formats that can be edited in another software can be delivered to the customer.

Beginning requires a computer, modeling software and regular practice. Blender is free software and can also be used for commercial purposes according to its official license information. However, Blender may not be the right tool for every project; For mechanical parts that require precise measurements, different CAD tools may be more suitable. Blender

How do you get started?

First, learn the basic modeling tools. Practice creating simple shapes, dimensioning, arranging surfaces, and controlling the geometry of the model.

Then choose a single area of expertise. For example, you can design desktop organizers for 3D printer users or convert customers' drawings into digital models.

Prepare the portfolio in the third step. Design three different objects. Show not only a good-looking image of each, but also its dimensions, intended use, and the types of files you will deliver.

Next, research businesses that provide 3D printing services, product designers, and small companies that develop prototypes. The 3D modeling category on Upwork can also be examined to understand what type of services customers are looking for. Upwork

Sample scenario

A customer wants a custom-sized holder to organize cables on his desk. You first learn the cable diameter, the surface to be used and how to fix the product. Then you prepare the model, check the dimensions and send a preview to the customer. After approval, you deliver the agreed files.

There is no actual customer or revenue claim in this example. In real projects, factors such as the physical operation of the design, the material used and the printing method are important.

Advantages and disadvantages

Advantages: It can be done remotely, different sectors can be served and technical skills can be developed over time.

Disadvantages: The learning process takes time. There is competition. Measurement errors or incorrect geometry may cause the model to fail in printing.

Risks: Do not design safety-critical parts, medical device components or supporting structural elements without expertise and necessary verifications. Clarify in the contract the customer's right to use the drawings and intellectual rights over the design.

First week and first month plan

Complete a simple modeling tutorial and create two sample models in the first week. Expand your portfolio, learn file formats, and reach clients who really need design in the first month.
