How to make designs for 3D printing: a complete guide for businesses
3D printing has evolved from a tool for rapid prototyping to a real and scalable manufacturing method for sectors such as automotive, engineering, architecture and medicine. However, to realise its full potential, the process must start with an essential step: 3D design optimised for printing. Designing for 3D printing is not just about creating an aesthetic part, but also about adapting the design to the additive manufacturing process, reducing costs, development times and errors during production. In this article, we explain how to design for 3D printing from a business perspective, what professional tools you can use and how to optimise your parts for maximum technical and economic performance. What it means to design for 3D printing 3D design for printing is the digital stage of the additive manufacturing process. It involves creating a three-dimensional model using CAD or 3D modelling software, which is then exported to a printer-compatible format (usually .STL or .OBJ). The difference between a traditional design and one designed for 3D printing is that 3D printing is conceived from the outset with layer-by-layer manufacturing in mind, eliminating the limitations of conventional methods (such as injection moulding or machining), and taking advantage of complex geometries, material lightweighting and customisation without cost overruns. Why companies should design with 3D printing in mind More and more companies are redesigning their products and components with DfAM (Design for Additive Manufacturing) criteria. Why? At Additium 3D, we apply this philosophy to every project: design becomes a competitive advantage, not a limitation. How to design 3D parts professionally Designing for 3D printers requires precision, technical knowledge and a different mindset to conventional design. Define the function and requirements of the part Before modelling begins, identify what role the part plays in the product or system. This information defines the material, technology and tolerances for the design. 2. Choose the right technology Not all 3D printing technologies behave the same, and each has different dimensional limitations, tolerances and resolutions: Designing without taking into account the chosen technology can lead to structural failures or printing cost overruns. Each technology has a minimum recommended thickness: Avoiding walls that are too thin or details smaller than the laser dot size ensures accurate printing and resistant parts. 4. Design to reduce material and time Optimising material is essential to improve economic performance. With smart design you can: At Additium 3D, these optimisations have reduced manufacturing times by as much as 70 % and total costs by 50 % on some industrial projects. 5. Add tolerances and adjustments On parts that need to fit, it is recommended to leave 0.2 - 0.5 mm clearance, depending on the type of material and printer. CAD tools allow you to simulate assemblies and detect interferences before manufacturing, avoiding repetitions or rework. Professional 3D printer design software In business environments, the choice of 3D design software is key to ensuring accuracy and compatibility. These are the most commonly used tools: Designing 3D models for resin printing When the priority is precision and detail, resin 3D printing (SLA, DLP or LFS) is the most suitable technology. Design considerations: 3D models for resin printing are common in jewellery, dentistry, medical devices and high-end industrial design. Optimised design = cost-effective manufacturing A properly designed part designed for 3D printing not only prints better, but also reduces post-processing costs, improves durability and speeds functional validation. Some benefits we see every day at Additium 3D: In other words: intelligent design multiplies the efficiency of the entire production process.

How to prepare and submit your STL file for 3D printing in Additium 3D
If you already have your design ready, the next step is to make sure that the file is perfect so we can print it without any problems. Here I explain everything you need to know to prepare and send your STL file to Additium 3D and get the best quality in your printed piece. What is an STL file and why is it essential for 3D printing? The STL file is the standard format we use for 3D printing. This file converts your design into a mesh of triangles that the printer can interpret to produce your part layer by layer. At Additium 3D, we almost always work with STL because it is the most reliable and compatible with our equipment. What should you take into account when preparing your STL file to send it? What if you have the design in another CAD format? How to convert it to STL? If your design is in CAD formats such as STEP, IGES or DWG, you have to export it to STL before sending it. CAD programs usually have the option “Export as STL” or “Save as STL”. If you have doubts with this step, you can also send us the CAD file and we will help you to convert it so that everything is ready to print. Why is it better to send an STL instead of other formats such as OBJ? Although OBJ stores more visual information, what matters for printing is the geometry of the part, and there the STL is the king. At Additium 3D we optimise your STLs so that the print comes out perfect without losing detail. Where can you find resources to review or improve your STL file before sending it? If you want to make sure that the file is perfect, you can use free programs like Meshmixer or Netfabb Basic to fix possible bugs in the mesh. If you prefer, we will check the file before printing and let you know if we detect any problems. How to send the STL file to Additium 3D? You can send us your STL file through our contact form or by email. If the file is very heavy, we can coordinate a file transfer platform such as WeTransfer or Google Drive. When sending, always include: This helps us to give you a quick and accurate quote. Do you want to convert your STL to other formats such as DXF? If you need a 2D drawing or profile for cutting or milling, we can help you convert your STL to DXF with programs like Fusion 360 or AutoCAD. You only have to ask for it when you send us the design. At Additium 3D we take care of every detail of your file so that the printing is a success. We don't just print; we control the whole process so that the final part is exactly as you imagine it. We check the file, optimise the print and accompany you throughout the process. If you have any doubts or are not sure how to prepare your file, ask us without obligation. We are here to make your project a success.
3D printing of religious images: a new era for sacred art
3D printing technology has arrived in the world of sacred art to offer new ways of preserving and reproducing religious heritage. Thanks to advances in high-precision scanning and printing, it is now possible to make 3D replicas of religious figures that faithfully maintain all the original details, respecting both their artistic and spiritual value. In this article we will explore how 3D printing of religious images is transforming the conservation, restoration and reproduction of religious pieces throughout Spain and elsewhere in the world. What is 3D printing of religious images? 3D printing of religious images is the process by which physical copies of religious sculptures, figures or symbols are created using additive layering technology. Materials such as resins, plastics, ceramics or even metals are used, depending on the desired finish and strength. This type of printing makes it possible to manufacture customised pieces, make exact reproductions of historical sculptures or even create new figures adapted to contemporary tastes and needs, always respecting the essence of the original work. 3D scanning to preserve heritage forever One of the great revolutions brought about by this technology is 3D scanning to preserve heritage forever. Using high-precision scanners, it is possible to digitise religious figures and objects with an extraordinary level of detail. These digital archives not only make it possible to produce copies, but also to preserve for future generations the visual memory of pieces that would otherwise be exposed to wear and tear, the passage of time or possible damage. Thus, 3D scanning becomes an essential tool for museums, churches, brotherhoods and private collections interested in protecting their legacy. 3D printing of real objects, pieces, figures and religious objects The versatility of this technology makes it possible to tackle a wide variety of projects: from the creation of large 3D replicas of religious figures to the reproduction of small liturgical objects. 3D printing of real objects, pieces, figures and religious objects is particularly useful in restoration processes, where it is often necessary to manufacture parts to replace damaged or lost elements, while respecting the original form. Moreover, as it is a highly customisable process, it is also possible to make adaptations in size, materials or finishes, always under criteria of fidelity and respect for the religious work. Personalised religious figures The possibility of creating personalised religious figures opens up new avenues of expression for both religious institutions and individuals. Thanks to 3D printing, it is now possible to reproduce images of saints, virgins or biblical scenes adjusted to specific sizes, artistic styles or specific needs. This customisation also makes it possible to add unique details, specific facial expressions or to incorporate symbolic elements that reinforce the spiritual connection of each work. Exact replicas of religious sculptures with unprecedented fidelity Traditionally, making copies of religious sculptures was a laborious process and, in many cases, inaccessible to small temples or individuals. 3D printing of religious images has democratised this possibility, making it possible to 3D print identical copies of any size with great fidelity. Every fold of the robe, every facial feature or every small ornament can be replicated with a level of detail that makes the reproductions virtually indistinguishable from the originals. Applications of 3D printing and 3D scanning in sacred art The possibilities offered by this technology in the religious field are manifold: Thanks to 3D scanning to preserve heritage forever, many images that might have disappeared today continue to transmit their beauty and meaning to new generations. An opportunity for art, culture and faith 3D printing of religious images not only facilitates the reproduction of sacred figures and objects, but also opens a door to creativity, preservation and cultural dissemination. In a world where technology is advancing every day, respect and passion for sacred art find in 3D an irreplaceable ally to continue to move and accompany people through time.

But, before we start delving into these topics, let's cover the basics by answering some questions such as what exactly is 3D printing in dentistry, how long does a dental impression last or how a dental impression is made. We believe they will help you better understand how this innovative technology is changing the practice of dentistry. 3D printing for dentists 3D printing in dentistry is an advanced technique that uses 3D printers to produce accurate, customised dental models from digital images. This technology makes it possible to create dentures, crowns, aligners and other dental devices quickly and efficiently. 3D printing technology has revolutionised many industries, and dentistry is no exception. Thanks to advances in intraoral scanning and digital fabrication, dental treatments are now faster, more accurate and more personalised than ever before. 3D printing in dentistry enables the creation of dental models, aligners, crowns and other devices with an exact fit, optimising treatment time and improving the patient experience. What is 3D printing in dentistry? 3D printing in dentistry is an advanced technological process that replaces traditional moulds with highly accurate digital models. It uses intraoral scanners to capture a three-dimensional image of the patient's mouth. This digitised image is converted into a CAD (computer-aided design) file, which is then used to fabricate customised dental devices using 3D printers. This process eliminates the hassles associated with conventional moulds, which can be uncomfortable and lead to fit errors. In addition, the digitisation of the procedure ensures greater efficiency in manufacturing and reduced material waste. What is a dental digital impression? A dental digital impression is the 3D representation of the patient's oral anatomy using digital scanning technology. This innovative method provides an extremely accurate model of the patient's mouth, allowing dentists to plan treatments more effectively. Unlike traditional methods, which require the use of silicones or alginates to take physical impressions, digital printing offers significant advantages: How is a 3D dental impression made? The dental 3D printing process follows a series of well-defined steps. In this article we explain the step-by-step process of creating 3D printed dental models from 3D scans. In short, the process would be: How long does a dental impression take? The time needed to make a dental impression depends on the method used. Digital impressions with an intraoral scanner usually take only a few minutes to complete, whereas the fabrication of a 3D printed model can take several hours or even days, depending on the complexity of the design and the material used. Thanks to the evolution of high-speed 3D printers, it is now possible to produce crowns, bridges and aligners in significantly shorter times, reducing the wait for patients and allowing dentists to optimise their workload. 10 uses of 3D printing in a dental practice Dental 3D printing offers a wide range of applications in dentistry that improve treatment accuracy and the patient experience. Here are 10 outstanding uses of this innovative technology in dental practices and how it is changing the way dental professionals work. 1. Customised dental models One of the most common uses of 3D printing in dentistry is the creation of accurate dental models. These models are used for treatment planning, showing the patient the procedures to be performed and for designing orthodontic appliances. With a dental 3D printer, practitioners can produce detailed models that accurately reflect the patient's oral anatomy. 2. Dentures and bridges 3D printing of dental prostheses is another key application. Thanks to this technology, it is possible to produce partial and complete dentures that fit perfectly in the patient's mouth, ensuring a comfortable and precise fit. In addition, dental 3D printers make it possible to significantly reduce production time and costs compared to traditional methods. 3. Crowns and veneers Dental 3D printers enable the production of high-precision dental crowns and veneers. These parts are digitally designed and then printed in biocompatible materials that are both aesthetic and durable. With dental 3D digital printing, dentists can offer quick and customised solutions to restore the aesthetics and functionality of their patients' teeth. 4. Surgical guides for implants In the field of implant dentistry, 3D printed surgical guides have greatly improved the accuracy and success of procedures. These guides, designed from digital scans, allow dentists to place implants with great accuracy, minimising errors and reducing surgery time. 5. Orthodontic appliances 3D printed orthodontic appliances are becoming increasingly popular due to their ability to provide a precise fit and superior comfort. Clear aligners, for example, are manufactured using 3D orthodontic printers that ensure an exact fit to the patient's tooth structure. 6. Customised dental implants With dental 3D printing, customised implants can be manufactured for each patient. This ensures better integration with the bone and a reduced risk of post-operative complications.
