What Is 3D Modeling?

Monday, February 28th, 2022

3D modeling is one of the most powerful and effective ways to turn 2D eCommerce operations into immersive 3D retail experiences. Unlike scanning techniques, 3D modeling from 2D images involves using CAD packages to manually build digital versions of source materials.

If modelers know the dimensions of products being modeled and have a couple of 2D images which show them accurately, they can replicate them quickly and cheaply.

There’s no need for site visits or proximity to a physical object. Instead, modelers could be anywhere in the world. And if they have the right skills, almost anything can be modeled with impressive fidelity.

The potential is almost infinite. But how should you commission 3D product modeling? There are two options here: outsourced or in-house modeling. Let’s quickly look at them and assess their merits and weaknesses.

Pros:

  • Clients supply 2D images and brief specifications for modelers to follow.
  • Modelers have access to cutting-edge software so that you won’t need to purchase expensive licenses.
  • CGTrader uses the largest database of 3D modelers in the world. Moreover, our community of thousands of experienced 3D modelers has been vetted and approved for quality, while our advanced quality assurance system provides an additional guarantee.
  • Modeling flows can be automated to save time.
  • Clients can provide detailed feedback about every visualization, ensuring they fine-tune the visual elements to arrive at a high-fidelity representation. So quality control is just as tight as when you keep modeling in-house.
  • CGTrader also offers a Digital Asset Management platform which makes organizing your 3D catalog simple.
  • Large batches can be modeled moderately quickly. It’s the ideal way to scale up from small 3D operations to full-scale eCommerce stores.

3D Printing: Which Technology Should You Choose?

Monday, October 11th, 2021

It’s an important question to start with. Essentially, the 3D printing technology you use to bring your design to life will depend on a number of other choices, including the material you want to use; the size of the item you’re creating.

Filament-based 3D printing

Industrial-scale filament printers like ours use a technique known as Fused Deposition Modeling (FDM). It’s ideal for models made from ABS, a material that provides a strong, accurate print. If you are looking to get the best 3D printing and custom 3D designs, then you can take help from the professionals of a 3D modeling agency.

The upside: ABS is great for functional applications. It matches 80% of the properties of real injected production material.

The downside: The surface quality of models produced with ABS is slightly rougher than with other materials.

Powder-based 3D printing

Several other techniques craft models in a bed of powdered material, though each has its unique differences.

  • Laser Sintering

Laser Sintering is perfect for materials like Polyamide, Alumide, Aluminum, and Titanium. The printer’s interior is heated until it almost reaches the melting point of your chosen powder, which is then spread out in a fine layer. A laser beam raises the temperature of the areas that need to be sintered together above the melting point, fusing them together to create your design!

  • Powder- and binder-based 3D printing

Materials like Steel and High-Detail Stainless Steel also rely on powder but are transformed using a technique that differs slightly from Laser Sintering. 

A thin layer of powder is rolled out on a platform before a binding agent is placed at specific points, printing a thin layer of your model that can bind to subsequent layers.
