Why would you pay so much more for a certain 3d scanner?
With the global rise in popularity of 3d scanning solutions, we’ve recently started seeing tons of new products pop on the market. Technology promising performance of the big brand 3d scanners at a mere fraction of the cost. Systems so easy to use, a child could do it. This inevitably means the end of the reputable, expensive 3d scanners, right? Why would anyone pay 10 or even 20 times more for something that does essentially the same thing? Or is it simply too good to be true…?
First things first, let's establish some categories. When it comes to 3D scanning products, there are various ways to classify them. For the purposes of this article, let’s simplify things:
- Cheap 3D Scanner: Think of this as the 3D scanning equivalent of an inkjet printer. It's the type of product you'd find in the homes of DIY enthusiasts and hobbyists, typically priced between $500 to $1000. Suitable for personal use.
- Professional-Grade 3D Scanner: This scanner is akin to the big color laser printing copier in an office setup. It's a productivity tool geared for businesses, priced at $10,000 or more. Businesses invest in these scanners for specific needs and higher-end functionalities.
Are there significant differences between cheap and professional-grade 3D scanners? In short—absolutely. Think of it this way: it's again like comparing your home inkjet printer to an office-grade printer. Both fulfill the task of printing documents when needed, yet the durability and robustness needed for a bustling office setting would overwhelm a standard home printer.
In our exploration of 3D scanning solutions, understanding the contrasting features between cheap and professional-grade scanners becomes pivotal. Let's dive into a side-by-side comparison to unravel how these scanners differ across various critical aspects:
Scanning Technology: the principle used to turn observed images into actual 3d data.
- Cheap 3D Scanner: Tend to use simpler, more basic principle typically adapted to their more economical hardware. These technologies may deliver decent results for smaller, simpler objects but might struggle with complex surfaces, challenging materials, or larger-scale scanning. Scanning challenging sections will either result in poor data quality or no data at all (holes).
- Professional grade 3D scanners: Utilize advanced technologies, allowing for greater precision, faster scanning speeds, and the ability to capture intricate details of large and complex objects.
Accuracy and Resolution**:
**Accuracy and resolution are both critical aspects of 3D scanning, but they represent different facets of the scanning process:
Key Differences:
- Accuracy focuses on how closely the scanned object's dimensions match the real-world object.
- Resolution emphasizes the level of detail captured in the scan, determining how intricate and detailed the resulting 3D model will be. It's crucial to differentiate this from mesh size, as some budget scanners generate mesh at resolutions below their capacity, resulting in redundant data.
- Cheap 3D scanners: While budget scanners might demonstrate decent accuracy within a single frame, they often accumulate errors when gathering data over multiple frames or throughout an entire scan. Consistently maintaining high accuracy across an entire scan demands top-quality components and a sturdy build, attributes commonly lacking in cheaper scanners.
Moreover, cheaper 3D scanners often offset lower-resolution cameras by either significantly reducing the field of view or offering a highly limited resolution. Consequently, this restriction either confines the scanner to work effectively only with very small objects or limits its capability to handle larger, simpler objects. - Professional grade 3D scanners: Their utilization of top-notch components and a sturdy build allows these scanners to yield precise data with heightened accuracy and resolution. This unique design also facilitates their ability to capture high-resolution scans while offering an extensive field of view.
Scanning speed and volume:
- Cheap 3D scanners: Lower-tier scanners often operate at slower scanning speeds and face constraints in capturing larger-sized or voluminous objects effectively. They frequently provide coarse resolutions for larger objects, or in cases of better resolution, restrict themselves to a smaller field of view, limiting their suitability to small-scale scans. Additionally, the hardware-intensive nature of processing data at high frame rates further hampers these scanners, constraining their capabilities.
- Professional grade 3D scanners: Boast faster scanning speeds and the ability to handle larger objects or larger volumes more efficiently, improving productivity for larger-scale projects.
Software and functionality:
- Cheap 3D scanners: Accompanied by straightforward software featuring basic editing tools and a modest selection of export options, these scanners are designed to address the needs of hobbyists or individuals engaging in uncomplicated projects.
- Professional grade 3D scanners: Feature advanced software with comprehensive editing capabilities, mesh optimization, alignment tools, and compatibility with professional-grade software or hardware, catering to complex project requirements.
Build quality and durability:
- Cheap 3D scanners: These scanners often prioritize lightweight and less robust designs, ideal for sporadic or light usage. Their construction typically incorporates more affordable components to manage production costs, compromising their potential and long-term durability.
- Professional grade 3D scanners: Feature sturdier constructions, durable materials, and components built to withstand prolonged usage in industrial or professional settings.
Post treatment tools and capabilities:
- Cheap 3D scanners: Best suited for hobbyists, educational purposes, and smaller-scale projects where precision and intricate details might not be critical.
- Professional grade 3D scanners: Packed with loads of more advanced features allowing to correct, improve and finalize scans to be as representative of the object as possible. The best ones will also have compatibility for other software such as quality control tools or CAD software.
Application suitability:
- Cheap 3D scanners: Very basic capabilities to keep the use as simple as possible. Usually offer to export the shape as is or, at best, as a watertight model.
- Professional grade 3D scanners: Tailored for professional or industrial uses such as aerospace, automotive, healthcare, and architecture, where precision, speed, and accuracy are crucial.
Higher-end scanners command a higher price due to their superior build quality, utilization of top-grade components, implementation of advanced algorithms, and inclusion of sophisticated software. As a result, they consistently deliver superior performance and sustain higher-quality scans over an extended lifespan.
However, while higher-end scanners offer remarkable capabilities, they might not be essential for every 3D scanning project. Entry-level scanners serve as a viable option for hobbyists, certain educational purposes, and simpler projects that don't demand high-performance features. These scanners are well-suited for occasional users handling light-duty applications, often meeting their requirements and budget constraints effectively.
Higher-end scanners are well-suited for demanding applications commonly encountered by businesses and professionals. They excel in situations where time, precision, and efficiency are critical factors. These scanners prove invaluable in scenarios where downtime or delays can significantly impact workflow, and errors or repeated iterations are costly.
Moreover, high-performance scanners shine in conditions where traditional methods struggle to cope with the complexity of parts or setups. Their capabilities become indispensable when the intricacy of components makes it challenging or time-consuming to model using conventional techniques. In such cases, the advanced capabilities of high-end scanners streamline the modeling process, ensuring accuracy and reducing the time required for intricate or complicated projects.
In summary, while affordable 3D scanners may seem appealing, our exploration highlights key differences. Budget options suit hobbyists but lack performance for professional use. Professional-grade scanners excel in precision and efficiency, making them essential for complex projects. Your choice depends on the project's demands, balancing budget, and performance.
