5 3D printing myths holding the industry back (and why they no longer make sense)
For years, 3D printing has lived in a kind of industrial limbo. Admired for its rapid prototyping capabilities, but questioned when it comes to actual production. However, while many companies still see additive manufacturing as a laboratory tool, the global market exceeds $20 billion and its industrialisation is no longer a future promise, but an established reality. So why are only a fraction of companies using 3D printing for final parts? The answer is not in the technology. It is in the myths. Myth 1: “3D printing is too expensive for mass production” This myth stems from a simplistic comparison: price per part vs. price per part. When comparing technologies, we often only look at unit cost in large volumes. In that scenario, injection moulding seems unbeatable. But that comparison ignores the key element: the cost of entry. A technical mould can cost between 10,000 and 50,000 euros. That investment pays for itself if you produce tens of thousands of parts. But what happens when the volume is 300, 500 or 1,000 units? That's where the paradigm shifts. Additive manufacturing eliminates: When you look at total cost of ownership (TCO) and not just unit cost, industrial 3D printing is competitive at a much higher volume range than many companies imagine. Moreover, moulds are not getting cheaper. Steel, aluminium and machining processes are becoming more expensive. In contrast, the productivity of technologies such as HP Multi Jet Fusion continues to increase. The real mistake is not thinking that 3D printing is expensive. It's not crunching the numbers. Myth 2: “3D printed parts are not strong enough” This myth is a legacy of the first generations of domestic 3D printing. But today's industrial additive manufacturing works with technical materials such as: In technologies such as MJF, parts exhibit mechanical properties comparable to many injection moulded plastics, with low anisotropy and good dimensional stability. But beyond the technical data, there is something more relevant: structural freedom. 3D printing allows the design of optimised internal structures, cellular geometries, integrated reinforcements and consolidation of parts that would be impossible with traditional injection moulding. It's not just about replicating what already exists. It's about redesigning for the better. In many cases, the printed component doesn't just meet. It surpasses the original design. Myth 3: “3D printing is only for prototypes” This is probably the most limiting myth. The idea that there is a clear boundary between “prototype” and “final part” is no longer valid in industrial additive manufacturing. In technologies like MJF, the same process that produces a working prototype is the same process that produces a final part. There is no technological leap between the two phases. The difference is not in quality. It's in volume. And that's where many companies get stuck: they validate with 3D printing, but when it's time to produce, they automatically go back to the mould out of inertia. Without asking themselves if it's really the best option. Myth 4: “We've always done it this way” This is not a technical myth. It is organisational. In many companies, the flow is automatic: Design → Printed prototype → Validation → Mould. Not because it is optimal, but because it is known. The lack of real knowledge about industrial additive manufacturing is one of the biggest brakes. It is not a question of budget. It is a question of mentality. The real question should be: Does it make sense to invest in a mould for a part that changes every year? For a reference that is produced in batches of 400 units? For a product with a short life cycle? Often, the answer is no. But nobody stops the process to question it. Myth 5: “To produce in 3D, you have to buy machinery” Another common misconception. Industrial additive manufacturing doesn't necessarily require investment in your own equipment. There are specialised partners that allow you to completely outsource production, without assuming: This reduces risk and allows you to evaluate the technology with real data before making structural decisions. 3D printing does not require changing the entire organisation. It requires strategic decisions based on context and volume. The real change: from physical warehouse to digital inventory One of the most profound changes introduced by industrial 3D printing is not technical, but logistical. Traditionally, inventory is physical. Large quantities are produced to reduce unit cost and stored. But every part in storage is a gamble. If the product changes, those parts become obsolescence. Additive manufacturing makes it possible to turn the warehouse into a digital archive. Inventory ceases to be stock and becomes information. You make it when you need it. No minimums. No risk. No capital tied up. In sectors with high version turnover, this is not an incremental improvement. It is a strategic advantage. The invisible cost of not adopting additive manufacturing Not using 3D printing when it makes sense also has a cost. That cost doesn't show up on the invoice, but it does: In increasingly dynamic markets, agility is a competitive advantage. Additive manufacturing enables: And that's not a marginal advantage. It is a structural transformation. So... when not to use 3D printing? It's also important to be honest. Injection moulding is still unbeatable when: The key is not to replace injection moulding. It is to use each technology where it makes sense. The question is no longer: “3D printing or mould? The right question is: ”What volume, what complexity and how often do you change this product?“ How to make the leap without risk If your company is in that middle ground between prototype and series, the step doesn't have to be radical. Start with a reference, a component of less than 500 units, a part with lead time problems, a code that changes every year..., to compare real numbers. Not only unit price. But: The result is often surprising. Additive manufacturing is no longer the future. It is the industrial present. The market is no longer debating
