On-Site 3D Scanning in Malaysia: When the Object Can’t Come to You

On-Site 3D Scanning in Malaysia: When the Object Can’t Come to You

Quick verdict: on site, the site decides the method. The object stays where it is, so the questions become access, power, light and downtime — not the spec sheet. A part that cannot move needs a handheld metrology scanner; a space that has to be documented needs LiDAR; an assembly measured again and again wants tracking.

Why on-site work is a different problem

In a measuring room the part comes to the machine, the temperature is controlled, the light is yours and the floor is level. On site the object stays where it is: a machine tool on its foundation, a mould in a press, a vehicle in a bay, a pipe run 6 m up. Measurement becomes a logistics problem before it becomes an accuracy problem — and the answer is usually a portable machine rather than a more accurate one.

This page is about that logistics problem. The technologies themselves — structured light, laser and LiDAR — are compared in Structured light vs laser vs LiDAR, and the format question in Handheld vs desktop vs tracked vs photogrammetry.

What actually changes on site

Factor	What it means on a working shop floor	How the job adapts
Access and line of sight	The scanner or tracker has to see the surface, and guarding, pipework and machine panels get in the way	We walk the route before unpacking; the setup, not the scan, is usually what takes the time
Power	The nearest socket is often far from the asset, and trailing cables across a live floor are not welcome	Battery machines: Combo+ Wireless up to two hours, SHARE SLAM S20 around 150 minutes; tracked systems run on portable batteries
Light	Daylight and high-bay lighting are nothing like a measuring room	Laser scanning copes with daylight far better than white-light structured light — one reason metrology handhelds suit shop floors and outdoor work
Temperature and vibration	The plant keeps running: the part is rarely at 20 °C and the floor is rarely still	We record the conditions and, where the tolerance demands it, say plainly that the job belongs in a controlled room instead
Dust, coolant and swarf	Real surfaces are dirty, oily or wet	Laser scanners read most of them without spray; the worst areas are cleaned locally and rescanned
Time out of service	The first question production asks: how long is my machine down?	Capture is minutes to about an hour for machine-side work, and most of the setup can happen while the machine still runs
Safety and access	Working at height, in confined spaces, or next to hot or live equipment	Method statement and plant induction where required — the scan is planned around the site’s rules
Getting the data out	The result has to leave site in a usable form	Mesh, CAD-ready model or inspection report, sent by link — what each output is good for is set out in what you receive from a scan

What we bring on site

Method	Documented performance	Suited to	Limits
Handheld laser metrology scanner — FreeScan Combo+ Wireless, UE Pro2	0.02 mm accuracy, volumetric 0.02 + 0.03 mm/m (0.02 + 0.015 with VPG); wireless with up to 2 hours on battery	Parts that cannot be moved: machine frames, tools, moulds, vehicle components	You still need optical access to the surface
Tracked system — Trak Pro2, Trak ProW	0.023 mm accuracy; 9.6 m³ (Pro2) or up to 8.6 m tracking distance and 206.7 m³ (ProW); marker-free	Large assemblies measured repeatedly, where the frame has to hold as you move	More equipment to transport and set up than a handheld
Handheld LiDAR — SHARE SLAM S20, S100 series	1 cm point cloud, 200,000 points/s, 1079 g, ~150 min (S20); up to 640,000 points/s and RTK/PPK georeferencing with 0.5–300 m range (S100 series)	Buildings, plant rooms, ship interiors, sites — documentation rather than measurement	Centimetre accuracy: no dimensional tolerance belongs on its output

Documenting a place is not measuring a part

Keep the two outputs apart. LiDAR produces a colourised point cloud of a space — genuinely useful for layout changes, as-built records and asset documentation — and it is not a dimensional inspection of anything. Nobody should be signing a tolerance off a centimetre-level cloud. If the question is “how close is this to the drawing”, that is a measuring job with a measuring tool.

Getting the job done

Access is the practical constraint, not the scanner: the tracker needs a line of sight to the part, so the setup is usually what takes the time. Power is rarely the issue with the wireless machines, and light is handled by choosing a laser rather than a white-light source. Temperature and vibration affect any measurement taken in a running plant — we will say so when a job needs a controlled environment instead.

Before the visit we need three things from you: the drawing and the tolerance you have to prove, a window when the machine can be stopped or run slowly, and someone who can walk the route with us. Most machine-side jobs are finished in a single visit.

And where the need is occasional — one plant survey, one suspect casting, a vessel that has to be documented before a refit — it is usually faster and cheaper to have us come and capture it than to buy a system that then sits idle. That is what our on-site scanning service is for.

Frequently asked questions

Can you scan a machine without dismantling it?

That is the point of working on site. Handheld metrology scanners reach into machine frames, under vehicles and along pipe runs, and the tracked systems hold the coordinate frame while you move around a large assembly. Nothing has to be brought to a measuring room.

Do I need power on site?

Not for the wireless machines. The FreeScan Combo+ Wireless runs up to two hours on battery with a rapid-charging dock, and the SHARE SLAM S20 up to 150 minutes. The tracked systems also run on portable batteries, with a wired mode where a cable suits the setup.

How long does an on-site scan take?

For a machine-side job, the scanning itself is usually minutes to about an hour — the setup takes longer than the capture. LiDAR is walked at walking pace, so on a plant or building the limit is access and time on site rather than the equipment. Most single-machine visits are finished in one morning or afternoon.

What do you need from us before the visit?

The drawing and the tolerance you have to prove, a window when the machine can be stopped or run slowly, and someone who can walk the route with us. If the part is hot, guarded or in a confined space, tell us in advance and we will plan the method statement around it.

How large an object can be covered on site?

The FreeScan Trak ProW tracks up to 8.6 m away with a 206.7 m³ working volume, holding volumetric accuracy from 0.046 mm at 15.6 m³ to 0.127 mm at 128 m³. SHARE SLAM LiDAR has no practical object limit — you walk the site.

What do I actually receive from a LiDAR scan?

A colourised point cloud of the space, georeferenced where RTK is used on the SHARE SLAM S100 series. It is documentation you can measure distances from and model against — deliberately not a substitute for dimensional inspection of a part.

Next step

We demonstrate in Kuala Lumpur and on customer sites across Malaysia, and we will scan your own machine, mould or part where it stands so you can judge the result before deciding. Book a demonstration or send us a part to scan.
