Laperos vs Zenite
Polymer · grade comparison
Laperos and Zenite are both polymer grades. Zenite is the more ductile: elongation 3.5% versus 2.5% for Laperos. Zenite is lighter (1.4 g/cm³ vs 1.61 g/cm³ for Laperos) and Laperos is stiffer (14 GPa vs 11 GPa). On the shop floor, Zenite machines more easily (good vs fair).
ZeniteChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
Laperos vs Zenite: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all polymer grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

Laperos vs Zenite — frequently asked
What is the difference between Laperos and Zenite?
Laperos and Zenite are both polymer grades. Zenite is the more ductile: elongation 3.5% versus 2.5% for Laperos. Zenite is lighter (1.4 g/cm³ vs 1.61 g/cm³ for Laperos) and Laperos is stiffer (14 GPa vs 11 GPa).
Which is cheaper, Laperos or Zenite?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, Laperos or Zenite?
Zenite. Its machinability rates good (55/100) against fair (40/100) for Laperos; for welding the order is Zenite first (poor, 30/100) then Laperos (poor, 25/100).
