Printing Details
Bring your vision to life with high-precision SLA 3D printing. SLA, or Stereolithography, utilizes lasers to cure liquid resin layer-by-layer, creating incredibly detailed prototypes, intricate designs, and even functional end-use parts. creating incredibly detailed prototypes, intricate designs, and even functional end-use parts.

- What you need to know about our resin 3D Printing service
We offer an SLA resin 3D printing service in Crouch End, north London. SLA printing is capable of building extremely fine detailing. Most FDM and SLS 3D printers print at 0.1mm layer heights, our SLA printers print as low as 0.07mm.
The surface finish is the smoothest of all 3D printing technologies, it most closely mimics injection moulded products therefore it’s the closest thing to the finished product. It’s ideal for producing silicone moulds largely because the surface is smooth. Our resin doesn’t inhibit the curing of most tin and platinum-based casting silicones so its suitable for most moulding applications.
Microworkshops SLA resin 3D printing service, can offer quick turnaround times (1or 3 working days) and were competitively priced.

- What is Stereolithography
First patented in 1986, by Chuck Hall. Sterelithography machines use an ultra-violet light. They build models by changing liquid resin solid, as well as, photopolymerization. This process is repeated layer by layer until the solid model is complete. This forms each layer. Furthermore, highly intricate detail, can be achieved in a short space of time. There are two types of SLA printers: bottom-up and top-down. In our case we use DLP/MSLA 3D printers which are not technically the same as SLA printer, but for all intent and purposes they are the same. MSLA/DLP printers use a LCD screen to project the 405nm lights rather than UV lasers used by SLA machines.
Post Processing
SLA 3d printing requires the highest level of post processing. unlike other printing technologies the material starts as a viscous liquid which is cured by UV light into its solid form. When prints are finished supports must be removed, it must be washed in 100% IPA solution, further curing required to move the print from 'green state' to its final hardened form.
UV Curing
Additional UV curing is required to process the freshly printed part into its final form. The extra exposure to light increases the strength of the molecular bonds made and forms new ones. day light also cures prints but we use curing light to control its strength & stiffness more accurately.
Support Removal
Support structures are printed to suspend the print in place, without adequate support the print will fail to build. These leave small uneven surfaces where the supports contact the print, so extra care is needed to remove and sand off markings.
Sanding
SLA printing provides the smoothest surfaces of all 3d printing. Layer lines are virtually invisible to the naked eye, however layers thicker than 0.07mm benefit from a high grit wet sand to give it a perfect super smooth polish surface.
Washing IPA
SLA printed parts are made in vat or ‘pool’ of liquid, when they emerge from the machine they’re covered in sticky viscous resin. Cleaning this resin takes the strongest alcohol solution, it’s not nice to work with were here to take the headache for you.
- Part Orientation
Part orientation defines where the supports will be placed which makes it a important factor for the final finish. Usually if there are any surfaces that have a tight fit with another part, it is important to orient the part so no supports are located in these mating areas, otherwise the marks left by the supports could interrupt the tolerance of the fitting. If the print is purely for show, or ‘cosmetic’ then the part should be orientated so that the most visible surfaces do not need supports.
In theory if all the supports have been removed and it’s printed at the finest layer height setting then there should be no visual difference whatever orientation your part is printed. In general, we pick the orientation of prints however if you need a specific orientation, let us know when you send the file and we’ll certainly oblige.
PLA Plastic
Overview
PLA is a strong, stiff biodegradable plastic. Its processed using a FDM printer, meaning it enters the printer in filament form, its heated to melting point and extruded out the print head as it prints into its final shape. It has properties that we have found are suited well for a range of difficult geometries including forms prone to warping.
It has a remarkably low shrink rate of 0.1-0.2% which is how we produce forms within tolerance and free of warping.
The filament diameter is highly accurate (+-0.03mm) so parts are free of inconsistencies. All our PLA is kept dry boxes always, this ensures the plastic absorbs no moisture which would decrease print quality in ways you can and can’t see with our eyes.
Its elongation at break is 20% which prevents it from becoming brittle, provides a little flexibility and improves impact resistance.
Our default print settings apply a wall thickness of 1.2mm and a hexagonal infill pattern of 20% density. Our maximum infill density is 50%, anything more than that clogs the machinery and adds almost no extra strength.
Typically, its best suited for prototyping purposes, its cheap so it’s more affordable when many iterations are required. Its lower detail than SLA resin and the build lines are visible, but its accurate and more than detailed enough for a huge variety of applications.

Properties
Cost Effective
PLA plastic the most used filament in FDM printing as its cheap and has a great balance of mechanical properties that suit many uses. PLA is a great choice when you need large batches given its low unit cost.
Strong & Stiff
Its strong and impact resistant like ABS. Its lots more rigid than ABS and more environmentally friendly. Parts thicker than 10mm can withstand large forces without any permanent bending.
Accurate
PLA has an extremely low shrink rate (0.1-0.2%) which makes its great for functional parts that require high dimensional accuracy. Generally speaking if the part is less that 100mm long then it will be within 0.1mm of its target size.
Environmentally friendly
PLA plastic is derived from corn starch which categorizes it as a biomaterial. It’s not just recyclable, its compostable too. It can last some time in standard compost but commercial composts with elevated temperatures fully break it down in as little as 30 days.
Tolerance/Accuracy
The vast majority of our prints are within +-0.2mm (or +-0.2%). We offer a guaranteed tolerance of +-0.4mm (or 0.4%), however 95% of our parts are significantly more precise than the minimum tolerance we offer.
If the part is less that 100mm long, then it will be within 0.1mm of its target size.
In rare cases some geometries are prone to warping which can lead to results outside of the guaranteed tolerance, if this is the case, we can usually reorientate the print direction to compensate.

Look/Feel/Finish
Below you will see pictures of the PLA prints fresh out of the printer. Unlike resin PLA comes as it comes and not much can be done in the way of surface finishes. By default, we remove all printing supports. The surface is a little glossy. Build lines are visible up close when printing with a 0.2mm layer height setting.
