3D resin printing is a great process for creating prototypes, manufacturing small batches of production parts, and producing end-use parts that are not suitable for casting. Resin 3D printing works by converting liquid resins into solid objects. It’s an accessible and affordable technology that is perfect for performing fast and detailed prototypes or low-volume production of functional parts. If you’re new to the world of resin 3D printers, let this article serve as your one-stop guide. Keep reading to learn everything you need to know about resin 3D printing, as well as its benefits, limitations and best uses cases.
3D resin printing is also known as polymer or liquid resin 3D printing. It is a type of additive manufacturing that uses a liquid resin as a build material. It is similar to selective laser sintering (SLS) and fused deposition modelling (FDM) but uses a liquid resin rather than a powder. 3D resin printing uses photopolymers that are cured by light. A photopolymer is a mixture of a monomer, a photoinitiator, a chain transfer agent, and polymeric chain shuttles. They work by converting liquid resins into solid objects. The photopolymers used for this form factor come ready-topped so they need only be cures by light during operation-- no heat required at all
Resins can either contain solvents like water mixed together along with hour ultra thin coats/layers which helps reduce shrinkage when casting object Labour intensive
3D resin printers are used for prototyping and production of functional parts. Rendering 3D models into physical objects is achieved through a process known as photopolymerization. These days, 3D resin printers are used for more than just prototyping and production of functional parts. With them you can even render physical objects into existence! Resin works by photopolymerization - meaning that light is needed in order to cure it into a solid form. A UV rays source does this magical work which creates an object from nothing but transparent gooey substances once enough time has passed."
There are several types of resin 3D printers which are used for manufacturing end-use parts, prototypes and functional prototypes. These include: - SLA: This process uses an ultraviolet (UV) light source to cure a solution of liquid resin. This method is used for low-volume parts. - DLP: This method uses a conventional projector to cure a liquid resin. Parts manufactured using this process have high resolution, but are expensive and used for mass production. - LCD: This process uses a laser to cure a liquid resin. LCD is used for low-cost production of functional prototype parts at high volumes. - UV Curable resin: This process uses a light source to cure a liquid resin that is sensitive to UV light. UV curing resins are used to get high-quality parts at high volumes. - Photocurable resin: This process uses a light source to cure a liquid resin that is transparent to light. This process is used for creating parts out of materials that are not UV sensitive.
- Time and money savings - You can create large parts in a single build through the use of resin 3D printing. This is a great advantage for small businesses that produce a batch of small batches of parts every day. - Get the right design - Use this 3D printing process to iterate and modify your design until it is perfect. You can create multiple parts at the same time, which helps you save time. - Material selection - You can create parts out of different materials using resin 3D printing. This is an added advantage when you need an outsourced part in a specific material. - Functional, detailed parts - Due to the low-pressure environment, resin 3D printing creates high-quality, functional parts. These parts are often stronger than cast parts. - No need for moulds - You don’t need to make moulds for resin 3D printed parts, which saves money and time. - Small volume parts - This process is ideal for creating small quantities of parts and prototypes.
- Manual process - This process requires time, effort, and skill. It is therefore recommended for small quantities. - Low accuracy - This is common when you 3D print parts with a low-resolution model. - Short life - Resin 3D printing parts have a short lifetime and require regular maintenance. - Low strength - Although resin 3D printed parts are sturdy, they are not suitable for high-stress applications. - No colour - Resin 3D printing only allows you to print monochromatic parts. - Long production time - This process has a long lead time, which is mainly due to the curing process.
- Prototyping: Create low-volume, high-quality prototypes or functional prototype parts for your end-use parts. - Low-volume production: This is a great process for low-volume production of functional parts. - Engineering and design validation: You can use this process to design and validate your design before going into production. - Custom parts: Create custom parts for your business or for an outsourced project. - Tooling: Create parts for tooling in the early stages of designing your product. - End-use parts: Create end-use parts with a custom design and material.
When you are choosing the right resin for your printer, you should consider the following factors: - Environment: Choose a resin that is UV-sensitive. Make sure that the room where you are printing is well lit. - Part size: Select a resin that can print the part that you need. Small parts require a smaller amount of resin, while larger parts require larger quantities. - Layer thickness: Select a resin that can cure layers of the thickness that you desire for your part. The thickness of each layer depends on the required strength of the part. - Part type: Select a resin with a formula that is compatible with your printer. - Quantity: Choose a resin that comes in a quantity that you need. - Price: Choose a resin that is within your budget.
