3d printing is becoming mainstream as more industries use this technology to innovate better products with higher accuracy and faster turnaround time. In addition, in recent years, additive manufacturing has become more accessible so that even hobbyists can have their 3d printer and enjoy real-time printing on the go.
For making the 3d printing experience more profound to manufacture robust quality objects, you can fine-tune specific settings to amplify the final product's quality. If you are getting started and already into it, these easy 3d printing tips will help you save time and improve accuracy.
Export CAD file as an STL File
The 3D printing process needs CAD files to print objects, and the design needs to be exported in an STL file format. The STL file contains the complete design made up of small triangles that form the surface of that part, causing faceting. Based on design type and complexity, faceting will vary. Some common aspects that affect the faceting of an STL file are angle tolerance, chord height, polycount, and deviation.
It's essential to ensure higher quality and design intentions while creating CAD files to print the final product. There are several ways to optimise your CAD model to ensure the STL file is highly accurate and the final product prints with perfection. You can fine-tune the complex geometry of the design by adjusting the thickness, file size, and compression to create an accurate STL file. Once you are done with optimising your CAD model, import it as an STL file to ensure the highest level of product accuracy.
Read Design Guidelines
Most beginners ignore the fact that there are several 3d printing technologies, and each one has different design and printing guidelines. Hence, before you start creating a CAD design or a prototype, it's essential to understand and know the standard procedures of that technology. In addition, every additive manufacturing technology has its unique design considerations, and they are vital to know before you start.
Some popular technologies that people use for 3d printing solutions are FDM, SLS, SLA, DMLS, and PolyJet. However, before you begin with CAD designing or printing, do quick research on which technology will deliver the best output based on your product requirements.
For example, the majority of the additive manufacturing methods require support structures for overhangs in the 3d model. On the other hand, the laser sintering method does not need additional design support. The design guidelines will vary based on your end goals and what kind of product you need from this technology. If you need quick prototyping, then FDM technology is the best-fit method to accomplish your goals.
Choosing Right Materials
Picking up the suitable material is as critical as choosing the right printing technology. There are 50+ plastic, metal, and ceramic-based materials available for additive manufacturing. You can pick the materials based on the purpose and functionality of the product.
If you need a prototype, you can pick plastic-based materials with FDM technology to perform rapid prototyping. Once you get the prototype right, you can choose more high-quality and durable materials to print the final product.
Other criteria to select the suitable material are durability, strength, and rigidity level that you need in your product. You first need to define whether you will use the printed object outdoors or indoors, and it will come in contact with chemicals, heat, water, and so on. Based on your requirement, you can quickly get the best-performing materials for your design. Whether you 3d print in Brisbane, Melbourne, or any other area, you will find a wide range of materials.
Material Usage Optimisation
Bigger CAD models take a longer time to print and consume more materials that increase the product's final cost. However, several ways can help you reduce the excessive material without hampering the aesthetics or functional properties. For example, you can use the hollow tool to optimise the overall structure of your product and get perfect results.
Whether you opt for a 3d print online service or you plan to do it by yourself, ensure you first understand how much optimisation you need for the design. You can also opt for professional 3d printing services in Brisbane or where you live to optimise your 3d model for best results.
Post-Processing Methods
Using a 3d printing service to manufacture a product is one thing; you also need to pick the suitable post-processing method to attain the desired surface finishing. Similar to 3d printing technologies, there are several post-processing methods that you can choose for your product.
Some popular functional finishes are bonding, sealing, sanding, tumbling, and blasting. Or, you can also choose cosmetic finishes that include electroplating, clear coating, painting, vapour polishing and texturising. While you select a surface finishing, you need to ensure it's not affecting the product's overall functionality. Once you understand the different types of surface finishing options available, you can pick the right one to bring the desired results to your product.
As the popularity of additive manufacturing is growing, several companies now offer affordable 3d printing in Brisbane, Sydney, and other places to cater to all your requirements. In addition, you can easily opt for preferred printing technology & post-processing methods to make your product stand out.
Final Thoughts
Follow these easy DIY tips to save time and improve the accuracy of your product. 3d printing is broad, and you must pick the correct 3d printing technology, materials and consider other essential factors before you start printing your designs.
