What kind of business can you start with a 3D printer?
1. Subcontracting


Subcontracting is the quickest way to earn money with your 3D printer. You can offer 3D printing services for others. In this type of business model, you wouldn’t need to design your own parts. You’ll just take 3D models/STL from your client and you will 3D print it for them.
The best way to maximize your profit with this type of 3D printing business is to get niche clients such as artists, jewelers, fashionista and architectural modeling companies.
One of its key benefits for you is that it offers the simple and low-cost operation, without ever needing to develop your own designs. Plus, you need not go on the painstaking process of trial and error and the high cost of marketing.
3D Printing Business Model for Subcontracting
The process goes like this:
- A client will give you the 3D model for prototyping.
- You will give him a 3D printing quotation for his file.
- Once the client accepts, you will 3D print the model.
- You will send the client the prototype/product by post.
- Ka-ching! Get your profit.
Cost of Running Subcontracting 3D Printing Business
- 3D Printer for business – $300 to $30,000 depending on the type of printer
- 3D Printer Filament – $15 to $70 per spool depending on your supplier and material
- Rental space cost
- Marketing cost
Pros
- Simple to do
Safe way to earn money without spending much - Small investment capital
- Low cost of operation, depending on your skill in fixing and updating your 3D printers
- Fast return on investment

2. Spare Part 3D Printing Service
There’s also a market for 3D printing services offering spare part printing. These components may either be faced out by the manufacturer or they are no longer produced by the company. With this, you can help these individuals by 3D printing the part that they need.
Again, in this type of business model you don’t need a lot of cash or intricate ideas to start running a business. However, 3D modeling may be required, especially if your customer cannot find the spare part or tool part 3D printable file from sites offering tool files, like Traceparts.
Business Model for Spare Part 3D Printing Service


This works through the following process:
- Client gives you a ready-made file of the spare part they want reproduced.
- You give them a quotation.
- Once both parties agree on pricing, you 3D print the part according to the material and level of accuracy they need.
- Send the client the finished part through post.
- Ka-ching! Get your profit.
Depending on the scope of services you offer, the client may send you the actual broken piece for you to replicate. In this case, you would need to 3D model the part from scratch and charge the customer a higher rate for the time you spent on replicating the part.
Alternatively, you can ask your client to search for the 3D model of the spare part they need in websites such as MyMiniFactory, Traceparts, Thingiverse or SpareParts3D. Once they give you the file, you can 3D print this for them for a cost.
Costs to Consider
- 3D Printer for business – $300 to $30,000 depending on the type of printer
- 3D Printer Filament – $15 to $70 per spool depending on your supplier and material
- Rental space cost
- Marketing cost
Pros

3. 3D Modeling + Prototyping Services
Why is it great for a small business?
This particular business idea may apply mostly to the OEM losing its original design measurements, where you can offer to reverse engineer its part to recreate the product.
This involves setting up a 3D engineering design and prototyping services. It may also go further to mass producing the product in hundreds or thousands, depending on your agreement with the client.
In this case, you need to translate your client’s 2D CAD drawings or ideas into a working 3D model before 3D printing it. This means you will be taking responsibility over the design accuracy of your projects, instead of your client.
This business model is somewhat more complicated than the ones mentioned above, but it brings extra profit. In order to get clients, you need to establish reliability and credibility over the market.
The cost of 3D printing the parts is almost the same as the other business types above, but you need to add the cost of the CAD software and CAD labor. You might also want to add 3D scanning to your services.
Business Model for 3D Prototyping Services
The process may be something like this:
- Either the customer gives you a 2D drawing or a physical component which you need to translate into its CAD form.
- You give a quotation for creating its digital twin and the cost of 3D printing it.
- Once the customer agrees, you start working.
- If the customer provides a 2D drawing, you need to 3D model the part.
- If it’s a physical object, you need to reverse engineer it and produce a 3D model. In this case, you might need some special equipment such as measuring tools or 3D scanning devices to recreate it.
- Create the STL and 3D print the object.
- You need to test and validate the resulting product before sending it to the customer.
- Get your profit.
Here’s how to convert a 2D drawing to a 3D model:
Setup Costs
- 3D Printer for business – $300 to $30,000 depending on the type of printer
