Introduction — Start With the Real Problem
If you’re researching a 3D scanner, you’re not doing it out of curiosity — you’re trying to solve a real operational problem.
Across engineering workshops, manufacturing environments, and mining operations in Australia, the same issues come up:
- Parts don’t match the drawings
- Manual measurements introduce errors
- Reverse engineering takes too long
- Downtime delays production
For example, if a component fails on-site and there’s no CAD model available, the process often looks like this:
- Measure manually (slow and inaccurate)
- Send it out to be measured (delays)
- Estimate dimensions (risk)
Each option introduces cost, risk, or downtime.
A 3D scanner solves this by capturing the exact geometry of a part and converting it into usable data — but only if the scanner is suited to the job.
The challenge is not whether 3D scanning works.
The challenge is:
Choosing a scanner that fits your parts, your environment, and your workflow.
This guide will walk you through how to do that.
The 3 Things That Actually Determine Your Scanner
Most buyers start by comparing specifications.
That’s not how you should approach it.
The right starting point is your application.
1. What Size Are the Parts You’re Scanning?
This is the fastest way to narrow your options.
- Small parts — bolts, connectors, tooling, intricate components
- Medium parts — brackets, housings, fabricated assemblies
- Large objects — mining equipment, machinery, vehicles
Why this matters:
3D scanners are designed with different capture volumes.
A scanner built for small, detailed objects will struggle to scan large equipment efficiently.
Likewise, a large-object scanner will not capture fine detail accurately.
2. Where Will You Be Scanning?
Your environment affects how the scanner performs.
- Workshop → controlled, stable lighting, easier access
- Inspection lab → precision-focused, repeatable setup
- Field/site → limited access, time pressure, variable conditions
Why this matters:
Factors like lighting, access, surface condition, and space all affect scan quality.
A scanner that works well on a clean bench may struggle on a dusty mine site.
3. What Matters Most: Speed, Detail, or Precision?
Every scanning workflow prioritises one of these:
- Speed → capturing geometry quickly (e.g. downtime situations)
- Detail → capturing fine features (e.g. small components)
- Precision → repeatable measurement (e.g. inspection workflows)
Important:
You don’t optimise for all three equally.
Choosing the right scanner is about prioritising what matters most for your work.
Quick Decision Guide (Start Here)
If you want a simple starting point, use this as a shortcut.
Choose Artec Eva if:
- You need a flexible, general-purpose scanner
- You’re working mainly in a workshop
- You’re scanning a variety of parts
This is the most common starting point for engineering teams.
Choose Artec Leo if:
- You need to scan large equipment
- You’re working on-site or in the field
- You need mobility and fast setup
Choose Artec Spider if:
- You need high-resolution detail
- You’re working with small or intricate parts
Choose Artec Micro if:
- You need a repeatable, high-precision inspection
- You’re working in a controlled environment
Choosing Based on Your Application
This is where most buyers gain clarity.
Instead of focusing on specs, focus on how the scanner will be used.
Reverse Engineering in Workshops
This is one of the most common use cases.
You may be:
- Rebuilding legacy parts
- Capturing worn or modified components
- Creating CAD models from physical objects
Best Fit: Artec Eva
Artec Eva works well here because it balances speed, accuracy, and flexibility.
It allows engineers to:
- Capture geometry quickly
- Handle a range of part sizes
- Move between different jobs easily
Why this matters:
Most teams don’t need a specialised scanner straight away. They need a tool they can use across multiple applications.
Mining, Maintenance & Field Work
Field environments introduce different challenges.
You’re often dealing with:
- Large equipment
- Limited access
- Time pressure
- Harsh conditions
Best Fit: Artec Leo
Artec Leo is designed for mobility.
It is:
- Wireless
- Self-contained (no laptop required)
- Faster to deploy on-site
Why this matters:
During downtime, speed and accessibility are critical.
If the part cannot be removed or brought into a workshop, the scanner must go to the part.
Small Parts & Fine Detail
Some applications require a higher level of detail.
Examples include:
- Small components
- Tooling
- Intricate mechanical features
Best Fit: Artec Space Spider
Space Spider is designed for high-resolution scanning.
It captures:
- Fine edges
- Small features
- Complex geometry
Trade-off:
Higher detail means slower scanning and processing — but for these applications, accuracy is more important than speed.
Precision Inspection & QA
Inspection workflows are different from reverse engineering.
Here, the focus is on:
- Measurement accuracy
- Repeatability
- Consistency
Best Fit: Artec Micro
Artec Micro is a desktop scanner designed for controlled environments.
It:
- Automates the scanning process
- Reduces operator variability
- Produces consistent results
Why this matters:
In inspection workflows, consistency is often more important than flexibility.
Artec Scanner Comparison
This comparison gives you a high-level view.
However, the best choice still depends on your workflow, not just the specifications.
Understanding the Workflow (What Most Buyers Miss)
Capturing a scan is only one part of the process.
A typical workflow includes:
- Capture the object
- Generate scan data (mesh or point cloud)
- Process the data
- Convert to CAD (if required)
- Use for inspection or manufacturing
Where Most Teams Struggle
Many teams assume scanning is the hardest part.
In reality, the challenges often come after:
- Large file sizes
- Slow processing
- CAD reconstruction complexity
- Alignment for inspection
Key takeaway:
A scanner must fit your entire workflow — not just the capture stage.
Structured Light vs Laser Scanning
You’ll likely come across this comparison early.
Here’s the simple way to think about it.
Structured Light (Artec)
- Faster to use
- Easier to deploy
- Flexible across environments
Best for:
- Workshops
- Field work
- General engineering
Laser / Metrology Systems
- Higher repeatability
- Often require markers
- More controlled setup
Best for:
- Inspection labs
- High-precision workflows

ROI: What Actually Justifies the Investment
Most businesses don’t justify a scanner based on accuracy alone.
They justify it on the basis of time and cost savings.
Where ROI Comes From
- Reduced downtime
- Faster reverse engineering
- Less outsourcing
- Reduced rework
- Faster inspection
Example
If a failed component causes several hours of downtime:
- Waiting for measurement → delays
- Estimating dimensions → risk
Capturing the part immediately can significantly reduce both.
🇦🇺 Buying a 3D Scanner in Australia
The biggest difference locally isn’t the technology — it’s how you validate it.
Why Demos Matter
Specifications don’t account for:
- Surface finish
- Geometry
- Lighting
- Access
A proper demo tests the scanner on your actual part.
Why Local Support Matters
The real challenges often happen after purchase:
- Processing scan data
- Converting to CAD
- Setting up inspection workflows
Having local support makes a significant difference in adoption.
Common Mistakes to Avoid
Choosing Based on Specs Alone
Specs don’t reflect real-world performance.
Choosing the Wrong Scanner Type
Match the scanner to the application.
Skipping Real-World Testing
Always test your part.
Ignoring Workflow Complexity
Processing often takes longer than scanning.
Final Recommendation
If you’re unsure where to start:
- Start with Artec Eva for general use
- Add Leo, Space Spider, or Micro as your needs become clearer
The best scanner is the one your team can use consistently.
