SLA - Resin 3D Printing Case Studies

What is SLA 3D printing?

In SLA technology, a laser solidifies a photosensitive liquid resin, building up the model layer by layer. The resulting parts have the best surface finishes and highest resolution of our offer. It is also the ideal technology for the production of scale models and modelling figures, due to its detail and resolution.

Disadvantages of SLA Technology:

Very high quality 3D print finishes at unbeatable prices with SLA technology

If SLA technology stands out for anything, it is for its ability to work with a resolution of up to 25 microns, something unattainable with other technologies. This makes it possible to define surfaces with maximum detail, which can be seen even in the detail of Spiderman's suit in the photos, where even the mesh texture of the suit can be seen.

What materials are used in SLA 3D printing?

At Additium 3D we offer a wide variety of resins depending on the application.

This resin is versatile and is commonly used for prototypes and concept models. It offers a smooth surface and precise details.

Designed to withstand high temperatures, it is ideal for applications requiring heat resistance, such as engine parts or industrial components.

It offers flexibility and impact resistance, making it suitable for elastomeric parts, seals and flexible prototypes. It is mainly used in the healthcare sector. 

This resin is perfect for architectural and design models, as it allows the creation of detailed models with high precision. It is widely used in the dental and healthcare sectors. 

Designed specifically for casting, this resin allows the creation of models that can be used to produce metal parts through casting processes. It is used in jewellery. 

It offers excellent durability and abrasion resistance, making it suitable for functional and mechanical parts. Ideal for medical prototypes.

This transparent resin is ideal for applications requiring visualisation of internal details or for transparent prototyping. It is best suited for transparent prototypes.

FAQS 3D SLA PRINTING

If what the client is looking for is a maximum level of detail and precision, Additium3D always recommends without a second thought the use of SLA technology, or stereolithography. This manufacturing technique, patented in 1984, consists of the photopolymerisation of a resin sensitive to ultraviolet rays by means of a laser, which solidifies layer by layer to form the desired 3D model.

 

In order to offer the best possible service, Additium3D uses Formlabs technology with Form3+ equipment that has unique properties on the market. The Form3+ is the result of a constant evolution over a decade to reach an equipment that offers on the one hand an unsurpassed surface quality thanks to its precision and the 

Improved fine point supports; and demoulding and post-processing that makes it much easier to achieve clean and well-treated models, as long as it is under the control of skilled hands like those of the Additium3D team.

As with any 3D printing process, it all starts with the 3D design of the model to be printed and its export to an .STL format needed to work on the printing platforms.

 

Once the 3D model was made in .STL format, we used the Preform software to configure and maximise the printing space of 14.5×14.5×18.5 cm and minimise the necessary supports that support the print and that do not mark a surface with a resolution of up to 25 microns.

 

Once the printing is configured and after making sure that we have the necessary resin in the tank and we have completed the steps that the printer asks for, we proceed to the printing of our prototypes.

 

Once the manufacturing process is finished, it is time for the appropriate post-processing to obtain the best final quality. This process begins first in the Form Wash, a tank of Isopropyl Alcohol in which the 3D printed prototypes are immersed to remove resin residues and leave a clean piece.

Once this process of approximately 10 minutes is finished, we demould the pieces and introduce the prototypes into the Form Cure, an Ultraviolet oven in which we treat the 3D printed models for 30 minutes. In this way we get the material to reach its optimum properties. From here, Additium 3D applies its techniques developed over a decade of working with this technology to achieve the best possible finish for the parts.

As we told you in the first Blog post about SLA Technology and how Additium3D uses it to make prints with an amazing level of definition and detail.

SLA technology uses photosensitive resins that can vary in composition and properties. These resins are cured by exposure to UV light and are available in a wide variety of types, including standard, high-temperature, transparent, flexible and other resins.

In an SLA printer, a platform dips a layer of photosensitive liquid resin. Then, a UV laser is used to selectively solidify specific areas of the resin layer, creating a single layer of the part. The process is repeated layer by layer until the print is complete.

The main difference between an FDM (Fused Deposition Modelling) printer and an SLA printer is the manufacturing method. FDM uses thermoplastic filament that is extruded and solidified layer by layer, while SLA uses liquid resin that is cured with UV light. SLA tends to offer greater precision and fine detail, while FDM is known for its versatility and lower costs in some cases.
