New Top-down Industrial DLP 3D Printer,
DM400A
■ Carima launches DM400A, an industrial DLP 3D printer
Carima has finally launched the DM400A after an ongoing effort to develop a large build size DLP 3D printer with fast printing speed and high precision. DM400A introduced a top-down printing system to print large-sized output. The large-build size of 400x330x500mm ensures high stability of output. To irradiate high-resolution DLP light sources with high accuracy in area, two 2K resolution light sources were also installed at the top of the DM400A.

■ Advantages of the Top-down printing method
DLP 3D printers are generally built bottom-up. With its resin vat on the bottom, the output is printed upside down. This method prints small-sized output in a fine and stable method, but as for large output, it has weight limits. The supporters cannot hold the weight, which causes the output to fall off and fail.
The DM400A has the capacity of holding a maximum of 220 liters. Dual 2K DLP light source is mounted on the bottom and the DUAL 2K DLP light source is mounted on top of the equipment, irradiating light from the top. The light source, the digital projector screen, flashes an image of a layer from the top, curing a layer at a time. The cured layer is then lowered back into the vat and is repeated. Each time the build plate is lowered, the recoater, mounted on top of the vat, moves back and forth over the resin to level a new layer. While the Bottom-up method of the existing DLP 3D printer was designed to tilt against gravity, the DM400A is built Top-down to print stabile, large-sized output just like an industrial SLA 3D printer.
The additional benefit of the Top-down method is that replacing the vat film isn’t necessary. The Tilting process and repetitive printing causes tears and leaves marks on the film, but DM400A being a Top-down 3D printer, no longer requires film replacements. Only the large built-in build plate needs to be cleaned, and it can be used over the long term.
■ Take a closer look at the DM400A
The biggest advantage of a DLP 3D printer is that it prints fast. Its ability to cure the entire layer at a time allows fast printing speed out of all the available 3D printer types. Besides its Top-down method, DM400A has many more advantages such as great output stability, fast printing, large build size and convenient function.
1. DM400A 'Strong Point'
① Large Build Size, Fast Printing Speed
● Cures a layer at a time and with a large build size of 400x 330 x 500mm, it can print 57 dental models
② Multi Engine Technology (MET)
● Technology that controls multi-engine screen in order to print precisely on one large build size
● Dual 2K (2560 x 1600px) resolution UV Light Engine
③ Image Data Partitioning Process (IDT)
④ Overlay Synchronizing Technology (OST)
● Dual 2K DLP light source interpolation control technology for overlapping images
● Prints successful output by interpolating overlapping light
⑤ Excellent Light Uniformity
● Consistent light uniformity of 99% prints smooth surface and has an excellent reproducibility rate.
⑥ Loose Type Vat System
● Easy-to-change vat allows to easily change the resin.
⑦ Compact Vat Function
● Save resin by switching mode when printing small output. This function allows the printing of small output with little resin.
⑧ Built-in Temperature Controller
● 50℃(max) heated chamber to heat resin allowing printing of high viscosity resin of 6,000cps.
⑨ 11” Touch Screen Control Center
● User-friendly, large-sized touch screen for convenient usage.
● Monitor output in real-time with easy-to-use icon.
● Check resin availability and check the refilling process through the screen.

3. Compatible Resin
DM400A prints Elastic ToughRubber(ETR)90, a hard, rubbery material that is used for end-use parts. This material has high viscosity which requires high heating. DM400A's top-down method has a heated chamber that can heat up to a maximum of 50°C/122°F, making it the most suitable 3D printer to print rubber-like materials. Elastic ToughRubber prints the toughest rubber-like material throughout the industry. Additionally, the Elastic ToughRubber has high durability for actual usage. With a tear strength of 30 kN/m, 200% elongation and ultimate tensile strength of 20 mPa, ETR mimics leading injection molded thermoplastic polyurethanes. If you make parts from technical foams, rubbers or polyurethanes, ETR is your solution to additive manufacturing end parts and products.
