3D printing is still considered a relatively new manufacturing method. Although 3D printing technologies were invented decades ago, they’ve only recently gained widespread acceptance as viable options for producing components.
As a result, there are still some misconceptions and misunderstandings around 3D printing among both customers and manufacturers. Unlike traditional manufacturing methods like machining which have been around for so long that processes such as quoting and maintenance have become standardized, 3D printing is still being refined.
To support our customers in their 3D printing projects, we provide guidance on the important questions to ask throughout the process. These questions can be the foundation for a productive direct relationship.
The First Big Question: Did I Design for Additive Manufacturing?
The most important question to ask yourself is: “Is this part designed specifically for additive manufacturing, and do we understand how to optimize its design for this process?” This question is more complex than it might initially appear.
It’s common for customers to design parts with injection molding or traditional machining in mind, simply because these are the manufacturing methods they are most familiar with. We often recognize this immediately, especially if the design is relatively blocky with few features. However, additive manufacturing offers the ability to incorporate more features from the start, which can save both time and money.
For example, we frequently receive designs lacking threaded features. Later, customers ask, “Should we tap these holes?” In reality, they could have included threads in the original design but weren’t aware this was an option with additive manufacturing.
The Second Key Question: What Type of Material is Best for My 3D Printing Project – and How Do I Determine That?
At 3D Parts Unlimited, we offer a wide range of materials for additive manufacturing, and there are countless options available in the industry. However, many customers are unsure about which material is best suited for their specific part and seek our guidance in making this decision.
If you’re uncertain about which material to use, we are here to help you identify the best option. To assist you effectively, we typically need to know the answers to the following questions:
- What is the project’s application?
- Is the part typically produced with metal – and could it be made with engineered plastic instead?
- What quantity do you need?
- What is the desired surface finish of your part?
- What is the budget of your project?
By understanding the essential details, we can direct customers to the best process and material that will meet their needs.
For example, we recently worked with a major corporation on a tooling project involving a uniquely shaped part. They knew the part needed to be non-marring to prevent scratching other metal components, but they were unsure of the best way to manufacture it.
By asking these key questions, we were able to identify the ideal material and manufacturing process for their needs. Additionally, we provided tips on designing for 3D printing, which improved the lead times and reduced costs.
The Third Key Question: Is This 3D Printing Service Provider Qualified to Handle My Project?
Since 3D printing has not been around as long as other manufacturing processes, different shops often have different standards in place. Some may place a priority on operational aspects like facility cleanliness; while others may not see it as important. However, maintaining a clean facility is crucial for producing high-quality products.
A shop needs to have well-established processes in place to consistently deliver defect-free products. We always recommend you talk to your service provider about what they’re doing to ensure consistent, quality results:
What kind of processes are in place at your facility?- How often do you clean your facility?
- Do you regularly inspect your printers and build carts? If so, how frequently?
- Could I tour the facility if I’m nearby?
In addition to these questions, never forget to ask any manufacturer about lead times, capabilities, shipping rates, and any other aspects relevant to your project.
