In episode 111 of Hardware Startups with Fexingo, Lucas and Luna dive into microinjection molding — the specialized process for producing ultra-small, high-precision plastic parts used in medical devices, wearables, and robotics. They discuss why conventional injection molding fails below a certain scale, the unique tooling and machinery required (like screw diameter under 14 mm and mold temperatures controlled to within 1 degree Celsius), and how startups can access these capabilities without owning a $200,000 press. The episode centers on a case study of a hearing aid startup that reduced its battery housing wall thickness from 0.3 mm to 0.15 mm, cutting material cost by 22 percent while passing drop tests. Lucas and Luna also touch on the trade-offs between microinjection and 3D printing for prototyping versus production. A light donation segment appears near the end, reminding listeners that listener support keeps the show ad-free.

Episode 110 of Hardware Startups with Fexingo dives into fused deposition modeling (FDM) as a bridge tooling strategy. Lucas and Luna examine a case from a medical device startup that used FDM-printed injection mold inserts to skip six weeks of CNC lead time, producing 2,000 parts before steel molds arrived. They break down the material choice (Ultem 9085 vs. standard PLA), the cost savings (roughly $12,000), and the trade-offs in cycle time and surface finish. The conversation also touches on how a consumer robotics company used FDM tooling for its first three low-volume production runs, cutting per-part cost by 40 percent compared to machining. Hosts discuss when FDM bridge tooling makes sense — typically runs under 5,000 parts — and when it doesn't. Practical takeaway: hardware startups can reduce first production lead time by up to eight weeks with the right printed tooling strategy.

Lucas and Luna explore how hardware startups use selective soldering to handle through-hole components on mixed-technology PCBs without manual labor or full-wave soldering. They discuss the case of a medical device startup that cut assembly costs by 40% using a palletized selective soldering process, and explain when it makes sense to invest in selective soldering versus hand-soldering or outsourcing. The episode covers the equipment cost curve, cycle time trade-offs, and how early-stage hardware companies can 'design for selective soldering' from day one. Listeners learn a concrete manufacturing technique that saves money and improves reliability for boards with connectors, relays, or electrolytic capacitors.

Lucas and Luna explore how hardware startups use potting compounds — epoxy and urethane resins — to protect electronics from vibration, moisture, and shock. They break down the difference between potting and conformal coating, walk through a real example of a drone startup that potted its flight controller to survive 30 G impacts, and discuss why the cost per unit drops dramatically at scale. They also cover the messy reality of rework: once you pot a board, you can't easily repair it. A practical episode for anyone building rugged hardware.

In this episode of Hardware Startups with Fexingo, Lucas and Luna dive into Frequency Response Analysis (FRA) and why it's a game-changer for hardware startups building durable products. They explore how FRA helps identify mechanical resonances before they cause field failures, using the example of a drone startup that discovered a fatal 110 Hz harmonic in its arm assembly during prototyping—saving months of redesign. Lucas explains the physics of resonance with a tuning fork analogy, while Luna shares how a robotics company she advised used FRA to fix a motor vibration issue that standard testing missed. They also discuss practical FRA tools, from entry-level shaker tables to affordable software like ModalVIEW, and when startups should invest in this testing. A must-listen for founders who want their hardware to survive real-world conditions.

Episode 106 of Hardware Startups with Fexingo dives into acoustic leak detection — a method used by Tesla, Apple Watch, and medical device startups to find microscopic leaks in sealed enclosures. Lucas and Luna explain how the technique works, why it's faster than traditional dunk testing, and how a startup making waterproof drones used it to cut returns by 65%. They also cover cost, setup, and when a startup should invest in a dedicated chamber versus sending to a test lab. A practical episode for any hardware founder sealing a product against water, dust, or gas.

Episode 105 of Hardware Startups with Fexingo dives into rapid tooling — the unsung manufacturing bridge between prototype and mass production. Lucas and Luna explore why companies like Formlabs and Protolabs are seeing a surge in demand for aluminum and 3D-printed injection molds. They break down the cost and lead-time tradeoffs: a traditional production mold for a plastic part can cost $50,000 and take 12 weeks, while a rapid aluminum mold runs $5,000 and ships in 2 weeks. The catch? Rapid tooling only lasts for 1,000 to 10,000 shots versus hundreds of thousands for hardened steel. The episode uses the real example of a startup making IoT sensors that needed 5,000 units for a pilot deployment. By using rapid tooling, they validated their market without committing six figures to tooling. Lucas and Luna discuss when rapid tooling makes sense, the materials you can use, and the gotchas like cooling channels and draft angles. They also touch on the newer trend of 3D-printed injection molds for even shorter runs. A practical guide for any hardware founder facing the tooling decision.

Episode 104 of Hardware Startups with Fexingo dives into snap-fit design—a technique that eliminates screws, adhesives, and fasteners from product assembly. Lucas and Luna explore how a smart-lock startup cut assembly time by 40% by switching to a cantilever snap joint for its outer casing. They break down the tradeoffs: snap-fits reduce BOM cost and speed up production, but they create stress concentrations that can lead to creep failure over the product's life. The hosts discuss common pitfalls like undercut draft angles, the importance of ABS over polycarbonate for snap flexibility, and why finite element analysis is non-negotiable during prototyping. They also touch on how to design for disassembly when snap-fits are permanent—or use living hinges for serviceable access. Specific numbers include a 30% reduction in part count and a cycle time drop from 90 seconds to 55 seconds per unit. The episode ends with a question: when does snap-fit stop being a cost saver and start being a reliability risk?

In this episode of Hardware Startups with Fexingo, Lucas and Luna dive into stereolithography (SLA) — the 3D printing technology that gives hardware startups sub-50-micron accuracy for tight-tolerance prototypes. They break down when SLA beats selective laser sintering, how startups like Formlabs and Carbon made it accessible, and why a $3,000 desktop SLA printer can save months of CNC iteration. Specific focus on a case: a medical-device startup that used SLA to print a fluidic manifold with 0.1-millimeter channels, cutting development time from six months to three. They also discuss the trade-offs: brittle resins, post-processing curing, and why SLA isn't for production. No fluff — just practical insight for founders who need to get functional prototypes into their own hands fast.
