Description

How bricks are made

Every LEGO® element starts as plastic granulate. In an injection moulding machine it is heated, forced into a precision mould under high pressure and cooled until it holds its shape. These machines are the unseen heart of brick production, and few fans ever see one in person. This set makes that process its subject, which is a refreshing change from the usual vehicles and buildings. We do not have reliable details about how the model is laid out, so the parts list below is the best way to explore it.

Built for looking at

There are no minifigures, and the catalogue records 253 distinct elements across 1,205 pieces. On average each element appears just under five times, which points to a varied build with plenty of different shapes rather than long runs of identical steps. That suits a model inspired by machinery, where visual interest comes from detail and texture. It is best treated as a display piece for a desk or shelf, and it will appeal most to builders who enjoy intricate assemblies.

Greys, black and a flash of lime

Black, lime, light bluish grey and dark bluish grey are the main colours. Three of those are the kind of neutral shades you would expect from industrial equipment, and lime is the only bright colour among them. If you plan to reuse the parts, the large proportion of greys and black is practical, since those colours fit into almost any project, from vehicles to buildings. The parts list shows exactly which elements come in lime, which can be handy for signage or accent details in your own models.

Outside the regular themes

Set 40502 is filed among special editions rather than in a mainstream theme. We leave aside questions of how it was distributed, as there is no reliable information to rely on here. What matters for your collection is the inventory. The parts list lets you check which pieces you already own if you want to recreate the model, and the What can I build? tool on this page compares your bricks with other sets to show what else you could put together.
