MakerPi P3PRO crowdfunding project - MakerPi 3d BBS

With the purpose of making a more perfect 3d printer, we have collected a lot of questionnaire surveys from professional 3d printer users and resellers, we found the price and stability of the machine are concerned by most people,so we plan to develop and produce a new 3d printer with the below functions. During the developing, we will share the test data to you and initiate crowdfunding after completed, welcome to join us and share your suggestions.

Expected functions:

1. Stability printing but in low price: People can buy the optional upgrade parts if they need more expandable functions.

2. Smaller size to save shipping cost: Ensuring the printing area, the size of the machine is designed to be as small as possible, within 430*415*510mm

3. Switchable between single nozzle and dual nozzle: the working area of the dual nozzle is often smaller than single nozzle machine. In order to maximize the printing area of the machine, we hope to design the nozzles are switchable. When the users needs a dual nozzle, install the dual nozzle module, and replace the single nozzle module when the user needs a larger working area. 260* 260 * 260mm (Single nozzle mode), 210 * 260 * 260mm (dual nozzle mode).

4. Stable double-head structure:

4.1 Use steering gear and mechanical structure to make a certain nozzle liftable.

4.2 Consider the design and use precision machining to ensure that the relative position of the nozzle is within an acceptable range.

4.3 Use software compensation, obtain the value to be compensated by printing the standard model, and fill in Cura for compensation.

5. Use the dual extruder which can support flexible material: PLA/ABS/TPU/PVA

6. Use high temp nozzle in single nozzle mode(300 degrees),260 degrees standard in dual nozzle mode.

7. Heated bed up to 110 degrees.

8. Built in ABL solution

9. Extendable modules: can be extended with laser head, CNC, and mixed color nozzle, we also hope it can be expanded to .clay, ceramic material and even food.

10. Modular design: the machine is designed into modules, easier to assembly.

If it goes well, the main parameters to achieve our design goals are as follows:

1. Working area: 260 * 260 * 260mm (single nozzle mode), 210 * 260 * 260mm (dual nozzle mode)

2. Machine size: 430 * 415 * 510mm (estimated)

3 .Transport size: 610 * 510 * 260mm (estimated)

4. Lifting dual nozzle structure.

5. Nozzle temperature: 300° (single nozzle mode), 260° (dual nozzle mode).

6. Support materials: ABS, PLA, PVA, TPU and other materials.

7. Hot bed temp: 110°.

10. Can support extended functions: mixed nozzle, laser head, CNC, etc.

11. Power off resume.

12. Material break alarm.

13. Touch screen operation.

14. CPUs: STM32 F429

15 .Nozzle diameter: 0.4mm

Project Overview:

This is MakerPi.It is a 3D printing company with more than 8 years of experience.In the past 2020, under the influence of COVID-19, let us have more time to think about the development direction of the industry. As an innovative company that is deeply involved in the industry, we feel that we need to do something for the industry. After conducting an in-depth analysis of the market, we found that we need a more perfect machine, which can meet the needs of the current stage, and at the same time can provide new choices for customers who need to upgrade. What kind of machine meets the requirements? After investigation and analysis, we feel that at least four conditions need to be met: A has new features; B is more stable; C is more scalable; D is available to more people.
So there is this project: a multi-functional hybrid 3D printer-P3 PRO.
If you want to use a few keywords to describe P3 PRO, I think it should be: mixed head, liftable double head, all-in-one, scalability.

Below are some of the upgrades we have made to the machine, and we will continue to update them in the future.

About z banding issue,

We use CNC machined parts to fix the motor on top of the aluminum profile instead of the original sheet metal parts. In addition, we added a fixed limit device on the top.

Hello everyone,

Last week we have tested new firmware, we mainlytest the parameter printing speed, and the test record oof printing speed is asbelow:

Using the firmware (firmware version:20220311 V1.3.3 V1.2) and other parameters unchanged, we tested 60mm/s,70mm/s,80mm/s.

1.60mm/s: The printing time is 5:17:13

[attach]87[/attach]

2.70mm/s: The printing time is 5:01:42

[attach]88[/attach]

3.80mm/s: The printing time is 4:49:16

[attach]89[/attach]

Using the firmware again (firmware version:20220331 V1.3.5 V1.2), we tested 90mm/s with other parameters unchanged

1.90mmm/s: The printing time is 4:12:40

[attach]90[/attach]

It can be seen from the above data that from theinitial time from 5:17:13 to 4:12:40, the time has been shortened by 1 hour and5 minutes, which has greatly improved the printing speed. Of course, our testis still in progress. More progress, we will update later.Thank you!

Hello Everyone,last week we have upgraded configure the offsets for E2.

How to configure the offsets for E2? We originally did this by printing a caliper. Now we have upgraded by putting a cross markings on printing platform and moving the printhead directly to align it. It's easier and faster.For more content, please stay tuned for next Monday's update.

Hi everyone,

Optional PEI print plate,size 310*310mm,flexible, removable, can stick to magnetics very well. High strength and heat resistance.can use front and back side.
The flexible steel PEI sheet is made of high quality spring steel that won't kink or warp when you flex them, they just return back to shape!
Easy to adhere to the printing surface, easy to remove the prints, flex slightly to pop your print right off.
