Product Summary and Analysis: Form 3 Industrial 3D Printer

3D printers help businesses and smaller-scale manufacturers to save money by printing real-world products directly from digital files. Today, advances in 3D printing have made the technology even more accessible and affordable while delivering the accuracy and detail needed for commercial production.

Formlabs has taken the capabilities of 3D printing a step further with the Form 3, the latest release of its stereolithography apparatus (SLA).

The review “Formlabs Form 3 Review: Best Resin 3D Printer 2020” (All3DP, 4 March 2020) introduces the functionality and features of the Form 3 and why it is the “best” in comparison with other SLAs in the market.

The SLA is a specially-designed 3D printing machine that converts liquid plastic into solid objects. It enables a superior level of detail compared with fused filament fabrication (FFA) which makes use of a continuous filament of thermoplastic material, but the SLA process is more complex. The All3DP article describes how the Form 3 addresses this issue whilst delivering high quality 3D printing.

One of the unique features of the Form 3 SLA is its Light Processing Unit (LPU) which integrates its laser and mirror for better control and precision. Unlike most SLAs that use a stationery laser, the Form 3’s LPU is able to bounce a laser beam through a galvanometer, mirror, and parabolic mirror to ensure correct beam placement, delivering consistent and precise printing quality.

While the printer has a laser with an 85 microns spot size, the Form 3 is able to move it in much smaller increments with its constant line scanning process. This enables it to deliver parts with much finer 25 micron XY resolution, providing greater accuracy and flexibility when translating the CAD model to a finished part .

But where the Form 3 really stands out is its ability to simplify print management and minimise the time the user spends with the machine.

The process is simple and straightforward. The user designs a 3D model of the product using any CAD software. The printer’s PreForm software divides the model into production slices, adds supports, and does a preprint check of the resin tank cartridge and build platform. On pressing the Start button, the Form 3 does the rest, and the machine can be left unattended until the print has been completed.

The machine incorporates monitoring sensors that micromanage every aspect of a print. If anything goes wrong, the system will send and alert and email to the user.

A touchscreen on the Form 3, paired with a computer, allows the user to view the material cartridge in use, the amount of resin used by a given print, the final print time, resolution, the number of layers and a complete history of each print. Each print job is linked to the owner’s name, enabling companies to keep track of “who, when and what” so that they are able to backtrack to the source when they encounter an issue.

All the above functionalities come in a built volume of 145 mm x 145 mm x 185 mm, which occupies a smaller footprint compared with competitors such as the Original Prusa i3 MK3S which has a build volume of 250mm x 21mm x 21mm. The compactness of the Form 3 makes it easy to shift around and place in smaller areas of the office for space optimisation.

However, this is also the downside to this printer – it limits the size of the printing output that users are able to achieve. To address this, Formlabs has come up with a bigger alternative of the Form 3, called Form 3L. Dubbed “the first affordable large format resin 3D printer”, Form 3L is able to build volumes five times larger than its average competition all while maintaining the accuracy and ease of use of the Form 3.

In conclusion, the accuracy of the Form 3 and its ease of use make it a compelling choice for businesses looking for a detailed and reliable workhorse. It can be set up in minutes, and the hands-off process makes it stand out from other SLAs in the market.

Self Introduction

Dear Professor Blackstone,   My name is Ang Jin Yang and I am currently pursuing a degree in Telematics.   Unlike many of my peers, I do not come from an engineering background. I graduated with a Diploma in Infocomm Security Management from Singapore Polytechnic. While the course covered many interesting areas such as secure programming, defending the network and penetration testing, I feel that one of the most important things that I developed was the ability to apply logical and process thinking skills to solve problems.   After polytechnic, I wanted to further my studies in an area where I could apply these skills. I feel that engineering would give me this opportunity. Specifically, I decided on Telematics as it is an exciting field, with the emergence of autonomous vehicles and other smart transport solutions.   However, while I find technology fascinating, I believe that soft skills such as communications are just as important as technical knowledge. No matter...

Product Summary Draft 2

  As advancements in 3D printing progressively shapes the way businesses approach prototyping and production, the technology has become more affordable and accessible. The article “3D Printing in Manufacturing: Visualizing  A New Mode Of Production”(Adam, 2017) mentioned that “3D printers aren’t just making an impact at the consumer level. Instead, they’re slowly changing the way manufacturers think about design, prototyping and even production”. The article also states that “3D printing has grown into a $6.063 billion industry and boasts a footprint in a wide span of industries”. The growth of revenue from 2016 to 2017 was at 17.4 percent worldwide, which shows how much the world is slowly embracing 3D printing. FormLab is one such company to take the capabilities of 3D printing a step further with the recent release of the 3D printer Form 3. Form 3 is a stereo lithography 3D printer that makes use of a light source such as a laser or projector to cure liquid resin into har...

Product Summary - 3D Printer - Form 3

With the increase in usage and dependency on 3D printing. Fields such as prototyping and manufacturing have begun using 3D printing to aid them in their work. Formlab's recent release of Form 3 3D printer is one such product ahead of its competition.  Form 3's technology enables high quality printing with little maintenance and tweaking. Unlike traditional injection-molded prototype which may be very high in cost and taking weeks to product one single mold, the form lab 3 is able to produce the same product in a matter of hours and at a fraction of the cost. Being able to create prototypes without the need for expensive tools is a more cost efficient and safer method of creating products.  Form 3 has wide appeal with its use of a high precision laser that produces unparalleled printing quality, surpassing competitors that use FDM printers. Being one of the most versatile 3D printers on the market, it is ideal for high quality prototyping, casting and production. .  ...
