Introduction

3D printing is a simple technique to produce just about anything you think. You can make practically anything using a 3D modeling tool and a desktop 3D printer. However, 3D printing has remained relatively out of reach, with only a few firms and people developing the requisite equipment.

Thus, JLCPCB is making things easy for you. JLCPCB's service leverages industrial 3D printing machines, allowing clients to acquire high-quality prints at cheap pricing with quick lead times.

Types of 3D Printing

ISO/ASTM 52900 additive manufacturing - general concepts - terminology has classified 3D printing techniques into seven classes.

Binder Jetting:

Binder jetting puts a thin layer of powdered material onto the build platform, such as metal, polymer sand, or ceramic, followed by droplets of adhesive applied by a print head to bind the particles together. This constructs the part layer by layer, and after completed, post-processing may be required to complete the construction. Metal pieces may be thermally sintered or infiltrated with a low melting point metal such as bronze as examples of post-processing, whilst full-color polymer or ceramic parts may be saturated with cyanoacrylate glue.

Direct Energy Deposition:

Direct energy deposition employs focused thermal energy to fuse wire or powder feedstock as it is deposited, such as an electric arc, laser, or electron beam. A layer is created by traversing the procedure horizontally, and layers are piled vertically to make a portion.

Material Extrusion:

Material extrusion employs a spool of filament that is fed into an extrusion head equipped with a heated nozzle. The extrusion head warms, softens, and puts down hot material at predetermined spots, where it cools to form a layer of material, and the build platform then slides down to prepare for the next layer.

Material Jetting

Comparable to inkjet printing, material jetting involves depositing layers of liquid material from one or more print heads rather than ink on a page. The layers are then allowed to cure before the procedure is repeated for the following layer. Although support structures are needed for material jetting, they may be created of a water-soluble substance that can be removed after the construction is finished.

Powder Bed Fusion

In the process known as powder bed fusion (PBF), heat energy melts portions of a powder bed to produce layers, which are then layered atop one another to make a component. PBF includes both sintering and melting processes, it should be noted. All powder bed systems operate in essentially the same way: a recoating blade or roller applies a thin layer of powder to the build platform; next, a heat source scans the powder bed surface, selectively heating the particles to cause them to bond.

The platform lowers to allow the process to start over on the following layer once the heat source has scanned a layer or cross-section. The finished product is a volume with one or more fused components encased in unaffected powder. The bed is fully elevated when the construction is finished so that the pieces can be extracted from the unaffected powder and any necessary post-processing may start.

Sheet Lamination

Laminated object manufacture (LOM) and ultrasonic additive manufacturing are two distinct techniques for sheet lamination (UAM). UAM attaches thin sheets of metal using ultrasonic welding, whereas LOM employs alternating layers of material and glue to form objects with a pleasing appearance. Aluminum, stainless steel, and titanium may all be processed with UAM, which uses low temperatures and little energy.

VAT Polymerization

The two methods of VAT photopolymerization are stereolithography (SLA) and digital light processing (DLP). Both of these procedures employ a laser to selectively cure the liquid resin in a vat, building pieces one at a time.

With a wide range of manufacturing technologies, JLCPCB also uses SLA technology which...
