How To Choose the Best 3D Printing Resin for Your Projects?

Rather than extruding thermoplastic in layers, stereolithography (SLA) 3D printers cure layers of liquid resin with a laser on the build platform to create solid models. Resins are liquid polymers that mimic the performance of thermoplastics or have a one-use purpose, like jewellery casting. The significant advantage of SLA is the laser is not restricted …

File formats for 3d printers

How To Choose the Right 3D Printing File Format

Some 3D printing file formats hold more information than others, giving your 3D printer more detailed instructions. Whether this is beneficial depends on what you are printing and your desired specifications.  For example, STL is the most common 3D printing file format because it works for simple models but only contains external surface and shape …

Topology

How Topology Optimisation Creates 3D Printing Opportunities

3D printing unlocks unequalled rapid prototyping opportunities but getting caught up in the iteration cycle creates bottlenecks. With fewer iterations you can reduce time to final part and time to market, but it’s easier said than done with traditional, numerical workflow. The traditional process sees engineers applying loads to already-manufactured parts and evaluating where they …

Part orientation

6 Effects of Part Orientation on 3D Printed Parts

Many factors determine the accuracy and surface finish of 3D printed parts, but part orientation is up there with the most important.  Part orientation refers to how you print parts on the build platform, which dictates the print head’s travel. The cusp of it is that FFF 3D printers produce parts with anisotropic properties where the X, …

What is a Lattice Structure? – Optimise your 3D Printed Parts

A lattice is a repeating pattern of strips, an arrangement so practical that you can find it in everything from apple pie to 3D printing.  In 3D printing, lattice structures make parts lighter and stronger, solving strength and rigidity challenges. They are also relatively simple to produce, enabling most 3D printers to maintain high print …
