Compare the buyer-facing factors that matter after the spec sheet: service coverage, spare parts risk, controls, automation ecosystem, total cost of ownership, and resale confidence.

Buying dimension	Sisma signal	Procurement check
Service network	Sisma service coverage is not fully profiled in the database.	Ask for local technician location, response-time SLA, remote diagnostics scope, and the nearest spare parts warehouse.
Spare parts risk	Listed source ecosystem: IPG.	Confirm source, cutting head, chiller, control, optics, and nozzle availability before comparing quote price.
Control system	Observed controls: Sisma.	Verify post-processor support, CAD/CAM compatibility, remote access policy, and operator training language.
Automation ecosystem	Automation levels in database: Semi-Auto, full-auto.	Price the machine with realistic material handling, safety enclosure, pallet changer, and future expansion path.
TCO exposure	Published price ranges exist for 5 of 5 models.	Compare 5-year cost: financing, energy, assist gas, consumables, preventive service, downtime, training, and software.
Used-market confidence	Primary origin signal: IT. Premium global brands usually hold residual value better, while value brands must prove parts access.	Ask dealers for comparable used-machine sale prices, depreciation assumptions, and controller/software transferability.
