Print Request

Hello


My name is Jean-Charles and I'm currently an engineer student from France. 


I'm working for a company which is looking to invest in a 3D printer. The problem is that we need to print a part with a specific design in order to check the possibilities of the printer as we require high precision. 


So I need to find somone who possess a Cretr'14 kind enough to print and send this part to me. :) 


The firm can cover the fees.


Thanks

hi, Jean-Charles. My name is Karis Letelier and i'm a engineer student too.

Mi research center is looking to invest in a 3Dprinter, but we are not sure wich printer to buy. Do you have any experience with 3d printer?


Tha

nks!

In fact I am not an expert and the applications I am looking for are really specific. But I did some researches. Depending on your financial investment and performance expectations there are many possibilities. 


You can mail me at jean-charles.pelletier@ens2m.org for more informations. Leapfrog is providing good printers but let's not debate it here. 

Jean-Charles,
Your requirement of "high precision" is very vague.
Could you be more specific? (Part size, tolerances, etc.)

 

I am looking for a precision of X-Y axis 10-20µm and Z axis <10µm. 

The Creatr'14 shall fulfill these requirements. 

No. I'm not an expert but I don't know of any FDM style printer that will do that even commercial. (Leapfrog guys, correct me if I'm wrong.)
The high end objet printer we have at work is rated at +/- .001" (25.4 um)
Hope you have deep pockets.

 

Well in fact there's one recent model that is supposed to handle it, <2k€ moreover. 


Furthermore, the Creatr'14 supposedly have a positioning precision of : XY: 16.9 microns Z: 10 microns

You can check it in the specifications part of that printer's presentation. 1.2k€.


Truth is I doubt these claims so I'm trying to figure out by printing a testing design to measure it. 

Hi guys,

What I do know, is that either the printbed or the rods holding the carriage in the Leapfrog Creatr HS are not perfectly straight. So if you want to do a large print which covers like 75% of the bed length, then you cannot take a first layer of .2mm because at some points the nozzle will be too far from the bed while at other points it will be too close. I think that the deviation is some tens of millimeters.

Also, because the nozzle width is .35mm, the lines you are laying down are bigger than .35mm. So the minimum feature size is always larger than .35mm, independent of the minimum steps of your x and y axes. The z-direction is different because the layer thickness is independent of your nozzle diameter.
You can however buy a smaller nozzle with a diameter of for example .20mm.

I hope I helped you somewhat.


Kind regards,

Marcel

 

I saw the specs. Positioning accuracy is the easy part. I'm sure the spec is correct. 

FDM printing is like squeezing toothpaste out of a tube. The nozzle has a diameter of 350 um. (More like 400 um after it exits the nozzle) Each layer has to be squeezed against the previous layer and inner and outer layers perfectly.The amount of extrusion has to be controlled perfectly. Then you have slight variations in filament diameter, temperature, material shrinkage, etc. Each roll of filament will act differently, even from the same manufacturer. At work we have a new Stratasys Fortus which cost 10 times what this machine costs. For those machines you buy their filament in sealed cartridges so they have total control of it.


The Creatr 14 is probably a great machine. I'm saying the FDM process inherently doesn't have the level of accuracy you claim to need. My guess is that with very careful setup of the machine and slicing software you "might" be able to get +/- 100 um. 


Ask Leapfrog what to expect for the actual print accuracy.

Quick Start Guide

Installation clips
The following 3 clips will guide you through the installation process of your CreatrXL. By following these, you will be printing within 30 minutes. First start with unpacking the printer. Clickhere to see how you correctly pick up the printer

Part 1 of 3: Unpacking your CreatrXL

In this clip, you will be guided through the unpacking of a brand new CreatrXL. The unboxing along with the location of tie wraps which need to be removed are shown, as well as the process of a connecting the cables to the printer and computer.

Part 2 of 3: Software and configuration

In this clip, we will show you how to install the required software. The first step is to download and install the Arduino software to make it possible for your computer to connect with the printer. The next step is to download and install the Repetier Host Leapfrog software or that controlls your 3D printer. We have tried to make this as simple as possible and also provided direct downloading links per operating system.

SIMPLIFY 3D SOFTWARE
If you are using the new Simplify 3D software you can follow all the steps except for the Repetier-Host Leapfrog installation and using explanation. Simply download the software via the purchase link and before first use a pop-up will appear showing you the Simplify 3D Quick start guide. You can also download the Quick start guide or access it from the software via help –> Quick start guide. The quick start guide will briefly explain the functions of the software so that you can start your first print.

Please select you operating system and follow the descriptions in the movie.

Operating systemWindows

The first step is to download and install the Arduino software to make it possible for your computer to connect with the printer. The next step is to download and install the newest version of the Repetier Host Leapfrog software as shown in the clip. This software allows you to convert your 3D software file [STL for example] to a printable file [G-Code] and allows you to control your printer. The Repetier Host Leapfrog software contains standard CreatrXL Print Profiles. Just select the extruder, the filament material as well as the color and Repetier will automatically select the ideal print temperature providing you the best print quality possible. There is also a Leapfrog support button implemented in the software. A Mac version will be available soon.

If you have followed the installation procedure, but you can’t control your Leapfrog CreatrXL and the “6 commands waiting” message in Repetier-Host Leapfrog won’t disappear, you have to install the 2.8.28 drivers. Please see Solution can’t connect 6 commands waiting in Repetier-Host Leapfrog how to do so.

For a more thorough description of Slic3s settings please check this guide!

Windows 8
To install the Arduino drivers on a computer with Windows 8 follow these steps after downloading the Arduino software.

- Save unsaved work and write the instructions down
[your computer will reboot into startup options screen]
- Press the Windows Key and the ‘R’ key simultaneously
- Copy the command inside the brackets
–>[ shutdown.exe /r /o /f /t 00 ] – Select ‘Troubleshoot’
- Select ‘Advanced options’
- Select ‘Startup Settings’
- Select ‘Disable Driver Signature Enforcement’
- Install driver as usual via device manager


Mac

In this clip, we will explain you how you can generate a STL file using Sketchup. We show you what to download and how to export your design in STL.

Part 3 of 3: Making your first print!

In this final clip, the process of creating your first print will be explained. This starts with removing the callibration print that is already on the print bed. How to insert the filament and operate the Repetier Host Leapfrog software is also shown, which should culminate in your first 3D Print on the CreatrXL!

Google sketchupHow to export STL files from Sketchup

The first step is to download and install the Arduino software to make it possible for your computer to connect with the printer. You will then need to in stall this driver for OSX to recognize the hardware.

The next step is to download the Repetier software as shown in the clip. This software allows you to convert your 3D software file [STL for example] to a printable file [G-Code] and allows you to control your printer. We have developed standard print profiles for the CreatrXL. Please follow the instructions below to install the print profiles for Mac [not yet included in the video]:

- Download This file
- Go to your Home Folder on Mac and select “Go to Folder” from the Go Menu en type “Library/Application Support/Slic3r/” - Unzip the file you just downloaded and dump the contents in the Slic3r folder, it will replace your existing settings. If you want to keep your current settings as well, take the contents from each folder and put this in the same folder in the Home/Libaray/App../Slic3r folder.
