Gravotech Laser Table LS900

Frequently Asked Questions About Gravotech LS900

How does the LS900 compare to the Gravotech LS100 — and how do I know which one is right for my shop?

The LS100 is a compact, entry-level laser designed for smaller format work and lighter production volumes, making it a solid fit for a single operator or low-throughput environment. The LS900 is built for significantly larger media, higher production demands, and multi-material flexibility — particularly if you need the pass-through or plan to run the Edge dual-source configuration. If you're producing ID tags or signage at volume, or processing bulky objects, the LS900 is the more capable platform. Big City can help you evaluate which machine fits your current volume and expected growth.

Can the LS900 engrave directly onto blank metal tags — like the aluminum, brass, or stainless steel tags Big City carries?

Yes — the LS900 Fiber and Edge configurations are well-suited for engraving directly onto bare metal substrates, including the aluminum, brass, and stainless steel blank tags available through Big City Manufacturing. No marking spray is needed on most bare metals, and the fiber laser delivers clean, permanent marks with high contrast. If you're sourcing blank tags and marking equipment from the same supplier, Big City can help you confirm compatibility for your specific tag material and finish.

Does laser engraving on the LS900 replace metal stamping or embossing, or do they serve different purposes?

They serve different purposes and often coexist within the same operation. Stamping and embossing create a physical, raised or recessed impression in the metal — highly durable for harsh outdoor or industrial environments where the tag may be exposed to corrosion, abrasion, or paint overspray. Laser engraving offers far more design flexibility, finer detail, and the ability to mark a wider range of materials without tooling. Many shops use both: stamping for rugged field tags and laser for detailed signage, nameplates, or mixed-material work.

What exhaust or ventilation does the LS900 require, and is the integrated exhaust base sufficient for most setups?

Laser engraving — particularly of plastics, wood, and coatings — produces fumes and particulates that require proper filtration or exhaust to the outside. The optional Integrated Exhaust Base (#39145) is designed to filter and manage fumes at the source and is sufficient for many shop environments. However, facilities with higher production volumes, enclosed spaces, or specific air quality requirements may need supplemental ventilation. We recommend discussing your facility setup with Big City before installation to ensure compliance with local ventilation standards.

How does the LS900's laser engraving compare to rotary engraving (like the IS200 or IS400) for industrial ID and nameplate applications?

Rotary engraving cuts mechanically into the surface and performs exceptionally well on hard metals, thick substrates, and applications where deep, tactile marks are required — such as industrial nameplates or control panels. Laser engraving is faster, requires no physical tooling, and handles a much broader range of materials and design complexity, but mark depth is shallower by comparison. For high-volume tag and label production where speed and versatility matter most, the LS900 is generally the stronger choice; for deep-cut metal engraving on rigid components, a rotary CNC may complement it well.

Does Big City offer support or training after purchasing the LS900?

Yes — Big City Manufacturing supports customers beyond the point of sale. Reach out directly through the contact form or request-a-quote page to discuss training, setup guidance, and ongoing support options for the LS900. Gravotech also provides resources through GravoStyle™ software, and Big City can help connect you with the right documentation and assistance for your specific configuration.
