Laser Marking Titanium: Sample Approval Before Selling Engraved Parts
Fibre laser marking on titanium: decide by test results, not colour photographs
A titanium component may look like a promising job for a small engraving workshop: it is valuable, often supplied in short batches and may need a clear asset reference. Yet a decorative coloured mark on a demonstration coupon does not prove that the same process is suitable for a customer's finished part. This guide helps an independent engraver decide whether to accept a non-safety-critical titanium marking job, how to ask useful questions and when to recommend a separate identification tag instead.
Why titanium deserves its own test plan
Titanium alloys differ in composition, treatment and surface finish. An engraved line may be readable immediately but behave differently after cleaning, abrasion or further processing. The marking process can affect surface appearance and, depending on its intensity and the part, may influence properties that matter to an engineer. Avoid advertising a single laser setting as safe for every titanium grade. Ask whether the buyer needs simple visual identification, a machine-readable code or a decorative finish; those are three different acceptance tests.
Never experiment on a customer's medical implant, aerospace component, pressure part, structural fastener or other safety-critical item. Those jobs need a controlled engineering specification and relevant approval, not a general online guide. For such components, marking location, allowable material removal and process qualification may be specified by the manufacturer.
Three possible outcomes for a sample coupon
| Observed result | What it means for the quotation |
|---|---|
| High-contrast surface mark | Check legibility after approved cleaning and handling; do not assume it is permanent in service. |
| Visible recess or texture | Ask whether material removal is permitted and whether the part can tolerate the process. |
| Colour variation across the coupon | Reject a colour-matching promise until the exact alloy, finish and process are repeatable. |
A mark can pass one criterion and fail another. For example, a blue-toned mark may be attractive in a product photograph but difficult to read under workshop lighting. Conversely, a less decorative dark identifier might scan reliably. Choose acceptance criteria from the actual use, not the demonstration image.
What to request before accepting a customer's titanium part
- Material identification: ask for the alloy or grade and whether the surface has been blasted, polished, coated or chemically treated.
- Authority: establish that the customer owns or is authorised to mark the item. Do not reproduce third-party marks or protected manufacturer branding.
- Permitted location: obtain a drawing or photograph identifying the exact marking area, and confirm whether any region is excluded.
- Text and data: request an approved identifier, revision and minimum readability requirement. Separate customer asset codes from original manufacturer serials.
- Service environment: understand whether the mark will be wiped, abraded, exposed outdoors or subject to specialised cleaning.
- Acceptance sample: request an offcut or coupon from the same material batch, rather than using a visually similar substitute.
A cautious workshop trial
First check the machine manual, enclosure, extraction and operator training. A 1064 nm fibre laser presents serious eye and skin hazards and can generate harmful fumes; do not defeat guards or improvise exposure controls. Clean the approved coupon using the customer's permitted method. Establish a baseline photograph with scale and lighting. Test only within a documented process approved by a competent operator, without inventing power, speed or frequency values from a generic internet recipe.
Record the machine identification, lens or marking field, coupon batch, file revision, result and any observed discolouration or damage. Compare the marked coupon with the approved artwork. Ask the customer to accept a physical sample under realistic lighting and handling conditions. If a barcode is required, test it with the actual scanner; visual attractiveness is not a barcode grade. Retain the accepted sample or its controlled inspection record.
Machine selection: what ONAGONE actually lists
ONAGONE's current 20W/30W fibre laser listing describes a 1064 nm bench-top machine with supplier-listed 110 × 110 mm marking field and Raycus, Max or JPT source choices depending on variant. At the 31 October 2026 check, the listed variants were £2,594.37, with positive inventory recorded in Shopify Admin. However, the public product page displayed Sold out, so ordering availability needs to be resolved before a purchase can be promised. No published product specification independently confirms a particular titanium mark quality, controller compatibility or safety certification. Request a sample on the actual grade.
Hypothetical small-batch quotation
Imagine a customer asks for 25 supplementary titanium asset references on removable, non-critical pieces. The workshop quotes £15 per piece before VAT: £375 revenue. Assume £35 for approved coupons and cleaning consumables, £90 for six paid labour hours at £15, £12 electricity and extraction consumables, £30 machine finance/depreciation allocation, £25 expected rework and returns allowance, and £35 customer acquisition, payment and administration. Total illustrative direct and allocated costs are £227, leaving £148 contribution before fixed overheads, corporation or income tax and unexpected engineering review. This is a hypothetical model, not a market quote, case study or guarantee.
VAT is separate: if £375 is a price excluding VAT, a VAT-registered seller adds the appropriate VAT on its invoice and accounts for it. If £375 were VAT-inclusive at the standard 20% rate, net sales would be £312.50, reducing the apparent margin. A single rejected batch or engineering assessment could wipe out the example contribution.
When a separate tag is the better answer
Choose a removable or separately mounted metal asset tag if the customer cannot approve a permanent mark on the titanium itself. This may also make sense when the item is highly polished, thin-walled, costly to replace or likely to be refinished. The attachment must still be safe and authorised. Never drill an engineered part or modify its structure to make room for a label.
Frequently asked questions
Does a 30W fibre laser guarantee better titanium results than a 20W model?
No. Power is only one part of a process. Optics, controller, material, finish, settings and acceptance criteria matter. Compare real samples rather than watts alone.
Can I promise blue, purple or black titanium marks?
Not from this product listing. Colour and consistency depend on material and process; obtain reproducible samples and check whether the finish remains acceptable after handling.
Is marking a titanium bicycle component acceptable?
Only if the owner and relevant manufacturer permit the particular location and method. Safety-critical frames, forks and fasteners should not be marked without competent engineering approval.
Does the machine include titanium-specific artwork?
No titanium process guarantee or proprietary customer artwork is confirmed. Obtain the approved file and material evidence for each job.
