Industry: Consumer Products / FMCG | Process: FDM (PLA+) | Volume: 50 tooling inserts | Lead time: 5 days
The Challenge
A prominent Gujarat-based personal care brand was launching a new series of shampoo bottles. The launch packaging required thermoformed blister inserts — custom-shaped foam and cardboard holders produced on a vacuum thermoforming machine. Traditionally, the tooling for thermoforming is a machined aluminium positive mould. Lead time from a Gujarat tool shop: 4–5 weeks. Per-tool cost: ₹18,000. Total for 50 variants: ₹9 lakh.
The brand''s packaging team was evaluating the new bottle sizes in parallel with a product reformulation. Two packaging variants were ultimately scrapped after the aluminium tooling was ordered — a ₹72,000 waste. The new packaging director wanted a faster, lower-commitment process for the launch line.
Our Solution
For thermoforming of blister inserts, the tooling temperature never exceeds 80 °C and the pressure is below 1 bar. PLA+ (high-strength PLA) has an HDT of 65–70 °C under load, which is marginal — but with a layer height of 0.15 mm and 40% gyroid infill providing superior through-thickness thermal conductivity, our testing showed PLA+ thermoforming tools surviving 150+ pulls before surface degradation. For this application (50 launch units per SKU before design is confirmed), tool life well exceeds requirements.
Layer X produced 50 tools in 5 days across three FDM machines. Tool geometry was derived directly from the bottle CAD files provided by the brand''s packaging agency. Draft angles, release radii, and vacuum hole patterns were added by the Layer X DFM team. Dimensional inspection confirmed critical features within ±0.2 mm against design intent.
Results
| Metric | Machined Aluminium | Layer X FDM PLA+ |
| Cost per tool | ₹18,000 | ₹2,200 |
| Lead time (50 tools) | 4–5 weeks | 5 days |
| Total cost (50 tools) | ₹9,00,000 | ₹1,10,000 |
| Geometry change cost | ₹18,000 per tool | ₹2,200 per tool |
Three of the 50 bottle variants were revised after initial thermoforming trials. The geometry updates were incorporated and reprinted within 24 hours, at ₹2,200 per revised tool vs ₹18,000 for each aluminium rework. The brand''s packaging director commented: "The ability to iterate tooling in 24 hours changed how we work. We stopped treating tooling as a commitment and started treating it as a prototype."
The programme launched on schedule. The brand has since used Layer X for thermoforming tooling on three additional product lines.
