3D Printing Certification

3D printing and common production processes


Lucie Gaget on Jul 16, 2019 |

Originally made as a technique for fast prototyping, 3D printing certification, which is also referred to as Additive Production certification, has grown into a accurate manufacturing procedure. 3D printing certification is offering engineers and businesses the skill to both prototype and manufacture finish-use solutions and it offers substantial benefits above conventional producing procedures. These advantages contain enabling mass customization, rising style and design independence, letting for the reduction of assembly, and can provide as a charge-effective reduced quantity manufacturing method.

This page will support you to fully grasp the big difference involving 3D printing certification strategies and other production approaches to support you make your mind up which procedure is ideal for you. The page has been split into the next classes:


3D Printing certification and Conventional Production Approaches: Overview


3D Printing certification Approaches


There are various 3D printing certification processes: Selective Laser Sintering (SLS), Binder Jetting, Stereolithography (SLA), Poly-Jet, Fused Deposition Modelling/Fused Filament Fabrication (FDM/FFF), etc.


To know extra about the various 3D printing certification solutions, you can refer to our 3D Printing certification Processes webpage.


Standard Production Solutions

There are 4 most important family members of conventional producing processes: injection molding, machining, forming, and becoming a member of. Comparable to 3D printing certification, just about every manufacturing method has positive aspects and restrictions. For extra details, simply click on the processes summarized down below.


Production Course of action Comparison chart

The above facts is non-contractual, these are regular specifications for system assortment functions. True specifications rely on the device, device maker, and material variety. It is your duty to make sure that the course of action you decide on is tailored to your product.


Deciding upon the Proper Method

To support in the collection of a manufacturing process that finest fits the desires of an software, it is crucial to 1st detect your specifications. There are several essential issues you should check with yourself when determining on the proper process.

Quantity: how substantial is the manufacturing operate?

Conventional manufacturing procedures like forming and injection molding are much more suited for huge scale manufacture, whereas 3D printing certification might be far more economical for small volumes. The chart beneath compares the believed charge for each unit of a GoPro cope with when created by way of injection molding (Quickparts) as opposed to Selective Laser Sintering (Sculpteo). In this scenario, 3D printing certification continues to be an economically legitimate selection for the very first 486 units.


Guide time: how shortly do you have to have your pieces?

The standard manufacturing technologies need molds to be produced and factories to be ramped up to velocity. As a consequence, it can get upwards of 15-60 days (and occasionally far more) to have the first element in hand. For 3D printing certification, the element can be printed on demand from customers and shipped without the need of any ramp-up or tooling, ensuing in a guide time as quick as 2 or 3 times. In the scenario of the Go Pro take care of, Quickparts quotes a guide time of 15 small business times for any volume from 25-1000 models, whilst Sculpteo estimates that 25 models with a direct time of 3 times and 1000 models with a guide time of 7 times.

Form/Complexity: what is your item condition?

For significant complexity pieces, fully assembled components or components that have to have to be personalized, using a Qualified 3D printer is the very best decision. Without a doubt, the selling price of these merchandise would be pretty large and from time to time they would just be not possible employing conventional production technologies these types of as molding, machining or forming.

Materials selection: what product do you need?

Classic manufacturing solutions like injection molding and forming can provide a superior product variety. When it comes to 3D printing certification, product collection is significantly sparser. FDM is minimal to extrudable thermoplastics, SLS requires thermoplastic powder that is equipment-particular, and SLA and Poly-jet purposes are constrained to photo-curable acylate and epoxy-dependent resins.

Complex things to consider

As the 3D printing certification technology matures, a bigger wide range of products with varying qualities are being released. The chart underneath introduces a variety of products and their comparative tensile strength. The legend on the correct identifies which systems are able of processing that substance.

As the chart demonstrates, thermoplastics these types of as ULTEM and Abdominal muscles can be processed by FDM/FFF printing as very well as injection molding and forming, demonstrating the skill of 3D printing certification to process high-power engineering plastics. However, SLA and poly-jet involve picture-curable resins, they are not able to process these particular varieties of materials. To compensate, expert 3D printer manufacturers’ have created products to replicate the overall performance of selected engineering plastics (like Digital Stomach muscles and Accura PEAK) and introduce supplies exhibit…
