What Can You Do with 3D Scanning?

In our previous article, we learned what 3D scanning is and how it works. Now we're getting to the really exciting part: What can we do with this technology? Where are the limits of transferring the physical world to digital?

3D scanning is not just a measurement tool - it's a bridge, a time machine, a preservation tool, and a creativity platform. It's used in a wide range from industrial manufacturing to museum archives, from medical implants to film effects. In this article, we'll explore real-world applications, success stories, and how you can start your own scanning journey.

Industrial Applications: The Future of Manufacturing

Quality Control and Inspection

Problem: Do manufactured parts conform to CAD design? Where are the deviations?

Solution: Scan the part, compare with original CAD. Obtain color deviation map.

Real Example: An automotive supplier performs quality control by scanning metal parts from molds. Deviations larger than 0.1 mm are detected instantly. This control used to take hours, now takes 5 minutes.

Advantages:

• 100% surface control (traditional methods only measure certain points)
• Fast feedback (immediate correction on production line)
• Documentation (digital record of every part)

Reverse Engineering and Spare Parts

Problem: Plastic gear of a 1980 industrial machine broke. Manufacturer bankrupt, no technical drawing.

Solution:

1. Scan the intact gear (10 minutes)
2. Clean mesh, convert to CAD (30 minutes)
3. Produce with CNC or 3D printing (2-4 hours)
4. Get the machine running again!

Real Example: A food factory created an archive by scanning plastic parts of a 40-year-old packaging machine. Now when any part breaks, they produce a new one within 24 hours. The machine used to be down for weeks.

Prototype Development and Iteration

Scenario: You made a handmade clay model. Want to transfer it to digital and edit in CAD.

Workflow:

1. Scan clay model (full-color texture)
2. Digital tweaking: Thickness adjustment, detail addition
3. Test prototype with 3D printing
4. Physical test, feedback
5. Digital editing and repeat

Advantage: Seamless transition between physical and digital. Designer's creativity meets engineering precision.

Jigs, Fixtures and Custom Tools

Use: On assembly line, special fixtures needed to hold parts. Different for each product.

Solution:

1. Scan the part
2. Design fixture in CAD (scan as reference)
3. Rapid production with 3D printing
4. Test, revise if necessary

Result: Custom tooling production time dropped from 2 weeks to 2 days. Cost reduced by 80%.

Art and Culture: Preserving Heritage

Museum Archiving and Preservation

Why Important: Historical artifacts deteriorate over time. Natural disasters, wars, accidents... Digital archive preserves cultural heritage.

Real Example: Palmyra Ancient City ISIS destroyed the ancient city of Palmyra in Syria. However, UNESCO and Oxford University had created a digital archive through 3D scans made beforehand. Now this data is being used for restoration.

Usage Areas:

• Digital copies of sculptures
• 3D models of historic buildings
• Documentation of archaeological finds
• Virtual museum tours (VR/AR)

Replication and Accessibility

Problem: Not everyone can see the Mona Lisa at the Louvre. Touching artworks in museums is forbidden.

Solution:

1. Scan artwork with high precision
2. Produce replica with 3D printing or CNC
3. Send to educational institutions, libraries
4. Touchable copy for visually impaired

Real Example: Smithsonian museum scanned much of its collection and made it open access online. Now people from all over the world can download these artifacts, 3D print them, or examine them in VR.

Website: Smithsonian Open Access (2 million+ 3D models)

Digital Restoration

Scenario: A broken sculpture piece. Missing parts exist.

Workflow:

1. Scan existing parts
2. Digitally combine
3. Complete missing parts using symmetry or historical records
4. Produce missing parts with 3D printing
5. Display restored sculpture

Medical Use: Life-Saving Technology

Surgical Planning

Problem: Complex brain tumor surgery. Where exactly will the surgeon cut?

Solution:

1. MRI/CT scan (digital internal image)
2. Skull 3D scan (external image)
3. Combine both
4. Print patient's skull with 3D printing
5. Surgeon works on physical model before surgery

Result: Surgery time shortened by 30%, success rate increased.

Personalized Prosthetics and Orthotics

Traditional Method: Plaster mold taken, measurement made, manually shaped. Takes 2-4 weeks, moderate comfort.

3D Scanning Method:

1. Scan patient limb (5 minutes)
2. Design prosthetic/orthotic in CAD (2 hours)
3. 3D printing (4-8 hours)
4. Deliver to patient (1-2 days)

Advantages:

• Perfect fit (digital precision)
• Light structures (lattice, optimized)
• Aesthetic (customizable colors, patterns)
• Fast (hours instead of days)

Real Example: e-NABLE community provided 10,000+ children worldwide with free prosthetic hands using 3D scanning and printing. While traditional prosthetics cost $5,000-50,000, 3D printed version costs $20-50.

Dental Applications

Usage Areas:

• Implant planning guides
• Clear aligners (Invisalign-like)
• Dental models
• Temporary crowns

Workflow:

1. Intraoral scanning (intraoral scanner - 2 minutes)
2. Digital design (crown, implant position)
3. 3D printing (dental resin)
4. Applied to patient

Result: Precision increased, patient comfort improved, treatment time shortened.

Body Scanning and Compression Garments

Use: Compression garments for burn patients, custom equipment for athletes

Example: A burn patient's body is scanned, perfectly fitting compression garment designed. Traditional method uses standard sizes, comfort is low.

Case Studies

Case 1: Automotive - Classic Car Restoration

Problem: 1965 Ford Mustang. Chrome bumper broken, no longer manufactured.

Solution:

1. Scan intact side
2. Mirror it
3. Digital repair: Fix cracks
4. Produce with metal 3D printing or CNC
5. Chrome plating

Result: Original part would cost $2,000+. Scanning + production $400.

Case 2: Film Industry - Props and Costumes

Use: Scan actor's face, produce custom mask or prosthetics.

Example: Marvel Movies For Thanos character, Josh Brolin's face was scanned. CGI was added on 3D model. Also, 3D printed face sculpture was used for physical reference.

Case 3: Fashion - Custom Fit Clothing

Concept: Custom tailored clothing for each customer. But cost is too high.

New Method:

1. Scan customer's body (photogrammetry or body scanner)
2. Parametric design: Standard cuts, custom measurements
3. Automated sewing machines
4. Perfect fit, reasonable price

Real Use: Brands like Nike, Adidas use body scanning for custom shoe insoles.
