1. The article starts with an unsubstantiated claim that digital manufacturing is causing a revolution without providing any evidence or data to support this assertion. This creates a false impression of the industry's actual state and potential impact on society. A more balanced approach would be to acknowledge both the opportunities and challenges that digital manufacturing presents, as well as its historical context and comparisons with traditional methods.
2. The article uses vague and ambiguous terms such as "technologies", "trends", and "on-demand manufacturing" without defining or explaining what they mean or how they work. This makes the text confusing and hard to follow for readers who are not familiar with the topic or the jargon. A clearer and more informative writing style would be to use specific examples, diagrams, or analogies to illustrate the concepts and processes involved in digital manufacturing.
3. The article focuses mainly on Shapeways as a representative of the digital manufacturing industry, without mentioning any other competitors, alternatives, or limitations. This creates an unbalanced and potentially biased portrayal of the market landscape, which could mislead readers into thinking that Shapeways is the only or the best option available. A more objective and comprehensive analysis would be to include a wider range of sources, perspectives, and criteria to evaluate the performance, feasibility, and sustainability of different digital manufacturing solutions and providers.
