HIGH SPEED EXTRUSION FAQS

October 02, 2018

 

1. How can the HSE move so fast?

We got rid of the traditional stepper motor-belt-and-pulley system and we replaced it with a linear motor system. Movement speed and Printing speed are two different things. Movement speed is how fast the printer nozzle can move on its own. Printing speed is how fast the nozzle can move while printing a good part. We have achieved movement speed because of our linear motors. We are able to print at those high speeds because of our non-slip hobs and powerful extruder.

2. How can you thoroughly melt the plastic enough when you print so fast?

We can bring the temperature of the nozzle from 20°C to 600°C in less than three seconds. Our ability to raise the temperature so high and accurately is what enables us to melt the plastic thoroughly by the time it exits the nozzle.

3. How does it reach 20°C to 600°C so fast?

Traditional 3D printers use a lot of energy when heating a large heat block to bring the nozzle to temperature. We decreased the thermal mass of the heat block, decreasing the amount of time it takes to heat.

4. How can you maintain accuracy at such a high speed?

By implementing linear motors we have reduced the number of moving parts. Our closed-loop-feedback positioning system not only allows you to print accurately but consistently. Our high-performance extruder ensures there will be no skipping or slipping during extrusion.

5. If you’re heating it up that fast, will you need a lot of power?

The HSE will have a universal power supply, so it can be plugged in to any outlet, 110V or 220V. The HSE will draw between 5-10A so the circuit breakers and outlet load need to be configured accordingly.  

6. Won’t you experience a lot of part warping by going so fast?

Our HSE will be a closed chamber with a multi-modal heating experience so you have minimal warping. Note: Warping is typically caused by a significant difference in temperature between the part and the environment. A closed chamber and heated build plate allows you to keep the environmental temperature consistent.

7. What is a linear motor?

In a stepper motor, the shaft rotates using magnets arranged in a circle. To move the nozzle back and forth, you have to use belts and pulleys, but a linear motor can move a nozzle by arranging the magnets in a straight line. Imagine unwrapping a servo motor and laying it flat.

8. When will the HSE start shipping?

Initial orders will begin shipping in Q4 2018 in order of reservation.

9. What is the current lead time?

Initial orders will begin shipping in Q4 in order of reservation. We are currently taking orders for mid-Q1 delivery.

PRINTING DIMENSIONS:

1. What are the footprint dimensions of the HSE?

2.6 x 1.2 x 1.6 M

2. What is the build area size?

740 x 510 x 650 mm

29 x 20 x 25.5 in

ACCURACY:

1. What layer heights can be printed?

< .1 mm

2. What is the accuracy of the machine?

The machine accuracy is <40 microns, 0.001 mm with the ability to hold 0.01 mm, X & Y = 0.001 mm resolution and can hold +/- 0.05 mm in motion.

HOZZLES:

1. What type of nozzle the printer have?

The HSE Platform will come standard with an all sapphire tip hot-end nozzle called the “Hozzle” – Essentium’s proprietary nozzle and heating unit.

2. Why do you call it a Hozzle?

Our Hozzle is a combination of a heater unit and nozzle in one efficient design.

3. How many nozzles does the machine have?

We will have three nozzle sizes: .4, .8, and 1.2 mm. There will be a single extruder, with a dual extruder available in mid-2019.

4. What is the maximum nozzle/extruder temperature?

600°C

5. Can the printer run filled materials? Is the hardware upgraded to minimize wear?

Yes, the printer can run some of the highest loadings available. There is no need to upgrade the system as it comes standard.

BUILD PLATE AND CHAMBER:

1. What build surface material is used?

It will be a high temperature, industrial glass bed.

2. Is the build plate heated and what is the max temperature?

Yes. The maximum temperature is >200°C, multi-surface heated bed.

3. Does the build plate need to be leveled manually or is it automatic?

You can do both - it has active automatic leveling, but you can also manually level the build plate.

4. How hot will the HSE chamber be?

It is a fully-enclosed, multi-modal heated chamber with an operating temperature of >110°C. This means you will be able to print high-temperature materials such as PEEK.

MATERIALS:

1. Is material supplied from you or can any material be used?

We will have materials certified for the platform, but you are welcome to use any materials.

2. Does the printer have a way to keep filament dry?

Yes, we will have a machine-mounted dryer system on the bottom of the platform that can hold up to four 15kg spools.

3. What filament size is used?

The machine is designed for 1.75 mm. You will be able to print materials on the full material pyramid from PCTG up to PEEK/CF.

4. If material comes from you will the settings be preprogrammed into the software or will the system be open?

The system will be open, however the materials will be certified to perform on the platform.

SOFTWARE:

1. Can process settings like temperatures be adjusted by the operator?

Yes, the system will be full open.

2. What slicing software is used? Is it a third-party software or something developed internally?

Customers will be able to use standard software like Simiplify3D and Cura, anything that works with Marlin style of G-code.

4. Will the software be upgraded periodically and will there be a cost?

Yes, there will be updates but it’s under user control. There are no additional costs unless the customer choses to upgrade to a premium software.

SERVICE AND SUPPORT:

1. Will a repair technician be available to come onsite to fix/troubleshoot the machine should there be problems?

Yes. However, the machine only has seven moving parts, with no belts or pulleys and it is built to SMT standards. In addition to onsite repairs, we will be able to answer questions by email and phone.

2.  Will there be a routine maintenance schedule for the machine where someone comes to service the machine?

Yes, this will be standard with the annual service contract

3. Is there online or telephone support for troubleshooting or printing help?

Yes.

4. If there is new or upgraded hardware on future machines will that be offered to existing machines? Will there be a cost?

Yes, future updates on the hardware will be available. There will be a range of costs and some updates will be free.

5. What is the initial warranty? And can additional warranty/service agreement be purchased to cover future service and repairs once the warranty expires?

One year. Additional warranty/service agreements are available for purchase.
