What is 3D printing?

How does it work?

3D printing is a manufacturing process in which a part is built by adding material layer by layer, by opposition to subtractive methods where material is being removed to create an object. First, you need to create a 3D file using a 3D modeling software and choose the material that you want  There are actually different manufacturing methods, it depends on the materials and techniques that you choose and need for your project.

There are powder-based methods, creating parts additively by sintering fine polymer powder particles, to fuse them together locally with a laser. You can get 3D printed plastic parts using this method. There are also processes to create 3D printed resin parts, using a liquid that is solidified by UV light layer by layer to create rigid and highly detailed parts.

All these technologies also offer the possibility to print with different 3D printing materials. The opportunities are really numerous, that is why 3D printing can be a really convenient manufacturing technique for diverse projects. If you want to use 3D printing you will also have to choose the 3D printing materials really adapted to the parts that you want to create.  

 

What kind of projects is it possible to create with 3D printing?

3D printing actually allows to use a wide range of different 3D printing materials and techniques, leading to really impressive projects: 3D printed homes, 3D printed jaws, 3D printed prostheses or 3D printed fashion accessories.

This technology is now useful and essential for diverse industries, from healthcare to fashion and architecture! It is even possible to create electronics projects, such as 3D printed robots.

What is laser cutting?

How does it work?

You actually have the choice between two different techniques: laser cutting or laser engraving. Laser cutting is a technology using a high-powered laser beam to actually cut the material, while laser engraving will simply engrave your part. This manufacturing technique will turn your 2D design into a real object.

 

What kind of projects is it possible to create with laser cutting?

If you choose to use this manufacturing method for your project, you will access a wide range of materials, from acrylic to wood. What is it possible to laser cut or engrave?

Thanks to our laser cutting service, you can laser cut or engrave acrylic, plywood, MDF, cardboard, POM. This will offer a lot of possibilities to create your projects, especially to create large parts at a lower cost, but still with interesting details. Laser cutting will be the perfect solution to make original custom items, such as custom visit cards or decorations.

3D printing or laser cutting: What is the best for you?

 

Both of these manufacturing techniques are efficient and quick to make good prototypes or even great end-use products. Some of your products might be doable with both! But one of these techniques is always more adapted than the other, it always depends on the nature of the project, the material, the size and the final use of your parts.

You will have to ask yourself several questions. Is your project doable by assembly of different laser cutting parts? Will your part be adapted to the 3D printing process or will they take too much space in the build chamber?

The benefits of 3D printing

Prototyping and production: Everything is possible with additive manufacturing

Additive manufacturing will really allow you to produce high quality prototypes. Using a 3D modeling software, you will be able to create simple or complex designs, and make as many iterations as you need at a lower price.

Additive manufacturing will really help you to create high quality prototypes but also finished products, at a lower cost than with techniques such as injection molding. By using 3D printing, you will definitely save time, money and improve your product development process.

Create complex designs

3D printing could really be a great asset for your company. Indeed, everything is now 3D printable from fashion accessories to mechanical devices. Professional 3D printers are now able to create any items, even with complex design, impossible to make in just one part with any other manufacturing technique.

Make the most of the various 3D printing materials

It is an interesting methods if you need to manufacture complex and resistant objects made in one part. Among the variety of materials available, you will certainly find one with properties meeting your expectations. Does your part need to be heat resistant? Flexible? Do you need special finishings? Find the perfect materials and all the options available for your project on our material pages!

If you are working in the medical field and need a biocompatible material, 3D printing is certainly the best choice. For instance, you can use our biocompatible resins to create prosthesis or other kinds of medical devices. That wouldn’t be possible with laser cutting, that is why, for these kind of project, additive manufacturing will be the perfect solution!

If you need to create a metal 3D object, 3D printing is the perfect method for you. For instance, you can 3D print stainless steel, or aluminium.

 

The benefits of laser cutting

Work on bigger parts and flat surfaces

The main difference between laser cutting and 3D printing is that laser cutting only allows to work on flat surfaces. If you need a 3D objects, you will have to assembly laser cut parts. It can still be a solution to give life to your projects, it will be cheaper, especially if your are planning to make big sized project. Indeed, laser cutting is great to work on bigger surface than additive manufacturing.

As this manufacturing technique is convenient to create large parts, at Sculpteo we used it to create tables for an exhibition.

You can choose your dimensions, and it will create your object with a really high precision. Keep in mind that some projects will be cheaper to produce using laser cutting, as they might be a little bit too big to be 3D printed and thus, they would be quite expensive. The price is really one of the biggest advantages of laser cutting. It is really becoming a convenient and efficient manufacturing techniques if you need to create products such as furnitures.

Many materials available for your laser cutting projects

Thanks to the various materials offered by this manufacturing technique, laser cutting will be perfect to create diverse custom items, such as custom visit cards, boxes, decorations, furnitures. For instance, to created our tables, we used MDF material (Medium-Density Fibreboard). You could even make circuit boards. Watch this video to see how it is possible to make laser cut circuit boards:

Like 3D printing, it can be great to produce amazing jewelry, but it will allow you to use different materials like wood. Check out our last blog post about the most impressive projects made using laser cut wood, it could be a great inspiration for you!

If you need to work on wooden parts, you will have to choose laser cutting instead of additive manufacturing. Indeed, it is not possible to work on wooden projects with professional 3D printers yet, laser cutting is way more adapted. You will get laser cut objects with a high quality.  

But wood is not the only material that you can laser cut. Acrylic is also a great material, offering a lot of possibilities in terms of transparency and colors.
