Importance of polystyrene in Prototype Development on CNC Machines and 3D Printers



Styrene Insulation

Every home should be insulated, and there are dozens of options available, ranging from styrene insulation to recycled denim insulation. All of these insulating products have advantages and disadvantages. Like polystyrene insulation green insulation, some of the greatest insulators are all-natural or created from recycled products.

Polystyrene insulation is a form of foam insulation used in both residential and commercial settings. Unlike its fluffier cousins, polystyrene insulation is highly stiff. It is a noise reducer and an insulator that can endure temperature fluctuations. It is waterproof and long-lasting, unlike other insulation materials. All of these factors combine to make polystyrene insulation a standout product.

Benefits of Insulation

  • External walls have been strengthened to prevent rain from penetrating the interior.
  • CO2 emissions are reduced as a result of reduced heat loss.
  • Lower energy/heating bills
  • Draughts through walls and around window frames are reduced.
  • Sound resistance has been improved, and the look has been improved.

3D Printer

A manufacturing method for producing three-dimensional (3D) solid objects. It allows for the creation of physical 3D models of items utilizing a layered development framework, in which layers are laid down in order to create a complete 3D object.

The construction industry must now follow in the footsteps of the manufacturing industry. The construction development has begun with digital technologies such as BIM (Building Information Management or Building Information Model) and VR (virtual reality), and a new large-scale additive manufacturing technology such as 3D printing could be the next stage. Additive manufacturing is defined by ASTM standards as the method of layering materials to produce products using 3D model data. In this way, binder jetting, direct energy deposition, material extrusion, powder bed fusion, and other manufacturing methods can be used.


Advantages of 3D Printing

  • 3D printing allows for the efficient use of materials and the creation of complex and custom shapes that are tailored to the needs of the user and the limits of the field (topologic optimization)
  • Complex part geometries can be created at a cost that is affordable.
  • Automation and robotics aid workers, resulting in a reduction of arduous human labour.
  • Architects have more creative freedom.
  • Building acoustic and thermal properties optimization.

CNC Machine

Computer Numerical Control(CNC) machines employ software incorporated in a microcomputer attached to the tool to automate the control of machine tools. It’s often used to machine metal and plastic parts in the manufacturing industry.

CNC hot wire 3D Foam cutters can be used to cut a wide range of materials. They can cut almost anything out of expanded polystyrene – EPS foam, for example. Hotwire CNC foam cutters use cutting-edge technology to create virtually any product with the most complex design in a quick, accurate, and cost-effective manner. Hotwire CNC foam cutting machines are used to make display letters, logos (3D logos), graphics, large-scale architecture models, signboards, P.O.P. displays,  decor elements, fair stalls, store props & displays, theatre or cinema decorations, labels for indoor and outdoor ads, mock-up products, all types of packaging, amusement, pipe insulation, architectural shapes, thematic props, and preCast.

On the building site, a CNC foam cutting machine? Yes, because this is the most efficient method for preparing external wall insulation on the job site, resulting in labour savings and superior polystyrene thermal insulation.

Advantages of CNC machining

One of the finest ways to cut high-density foam is with a CNC machine, which has a number of advantages.

  • The use of a CNC machine produces extremely precise results with constant product quality.
  • The procedure may also be easily copied because the same design or template can be used several times
    to make identical items, making it a useful tool for mass production.
  • CNC machines also increase the speed and efficiency of production.
  • Aside from the advantages of precision and efficiency, CNC machining is much safer than manually operated machines since a safety guard protects the machinery.
  • CNC machines work around the clock, including weekends and holidays, 24 hours a day, seven days a week.
    Only when necessary maintenance or repairs are required do they come to a halt.
  • CNC machines can be upgraded by upgrading the software that controls them.

Similarities between CNC Machining and 3D Printing

  • They produce 3D objects using 3D models.
  • They do so by following computer instructions.
  • They can work with both STL and OBJ files.
  • They are on the cutting edge of technology.
  • They’re quite common nowadays.


Even though both procedures are capable and beneficial, the most appropriate one will be determined by the material, geometric complexity, manufacturing volume, and budget. We recommend approaching a local or international provider and asking for their help to choose the ideal for your specific work. If you’re trying to make anything in-house, think about the machinery you have and whether it’s suitable for the job.
